I came to Dr. Yanni with a severe disc herniation and foot drop that had lasted over a month. He immediately understood the urgency, scheduled me quickly, and walked me through the risks and realistic outcomes. His honesty, skill, and care put me at ease, and the surgery was a complete success. His office staff is also outstanding friendly, supportive, and even helped me navigate the nightmare of disability paperwork. One year later, I'm fully healed, back in the gym, and running pain-free. Dr. Yanni came highly recommended, and now I know why. He gave me back my health and quality of life, and I couldn't be more grateful. read more

I saw Dr. Yanni for a second opinion after back surgery complications. He charged $5 per X-ray just to upload my scans, which no other doctor has ever done. When I asked if I was fused from my spinal fusion he said, "Of course not--you're only a year out." But when I told him my original surgeon said I was fused, he completely changed his answer and said, "Well then, I guess you are." It was obvious he was biased towards the other doctor instead of taking care of the patient in front of him.He avoided my questions, seemed dismissive, and offered no real help until I got visibly frustrated--and grabbed my things. He then gave me rushed "lip service" and casually said well let me check your strength in your hands and arms. Then Flippantly said, Yep you will need a neck fusion. Come see me when you are ready! He came across as arrogant and uninvested. I would not recommend him. read more

Lois G. I have been seeing Dr. Yanni for back pain for a number of years. I have had several procedures and most of them have been successful. I find him to be caring and listen patiently to my complaints. He suggests my options; we discuss them and move forward. I highly recommend Dr. Yanni for pain management. read more

I am an 84-year-old female and in my 11th month post-surgery. At this time I have minimal pain and no after-surgery side effects. I am so thankful Dr. Yanni accepted me as a patient. In his capable hands, I am well on my way to a complete recovery. Thank you, Dr. Yanni, for guiding me through the emotional roller coaster before the surgery. Spending all the time required for me to understand the necessity and urgency of the surgery. I wish someone had said to me before the surgery, "Hear all the possible things that can happen but don't dwell on them. It can drive you crazy. Have you ever read the warnings on your medication? Most of them end (even death)." Why do we take it? If you need cervical surgery, I recommend you trust Dr. Yanni; you can be assured he will do his very best for you as he did for me.

I started seeing Dr Yanni several years ago when I began to experience back pain. I had tried chiropractic care and had several epidural injections but saw no relief. After several consultations I opted for back fusion surgery of the L3, L4 and L5 disks. The surgery went well and after a year I was back to my normal life including golfing a couple of days a week. A year later I began experiencing pain again and tests showed a problem with my L2 disk. Dr. Yanni suggested a less invasive surgery to correct this problem. Again, the surgery went well and I'm happy to report that I'm back to golfing and living a normal, pain free life again, at 74 years young. I highly recommend Disc Comfort to anyone experiencing back problems read more

Great Dr. with excellent skills. Always in good hands with Dr. Yanni. This Dr. tells you what you need to hear and your quality care is his priority. Best results and patient satisfaction. read more

Dr Yanni is the best. He diagnosed my back problems as a cervical issue. He was very thorough and explained the diagnosis and resulting procedure with great clarity and caring. The procedure was a surgery on my cervical area which fused to together 3 of my vertebrae. Needless to say I was very anxious about the the success and any resultant pain that may occur. I suffered absolutely no pain during the healing process and all of my previous back problems were eliminated. I am so relieved that I chose Dr Yanni. He has been great during the follow up process and I highly recommend him for any spine related issues. I actually enjoy my follow up visits. read more

Dr. Yanni changed my life. I suffered for over a decade from pain, tingling, burning, and numbness in both hands & wrists, along with constant severe neck pain. An MRI revealed I had a previously unknown injury: a severely herniated disc and disc bulge were protruding into my spinal cord. Dr. Yanni performed a cervical spinal fusion. I followed all of his guidelines, and now, 18 months later, I'm completely free of spinal pain and feel like "Me" again. I'm incredibly grateful for his expertise and compassionate care. Highly recommend! read more

If you are looking for a neurosurgeon, don't look any further. Dr. Daniel Yanni at Disc Comfort is the one surgeon you should pick. i'm writing this review to help others who are looking for a neurosurgeon and want honest opinions. I used similar reviews in order to select Dr Daniel Yanni at Disc Comfort as my neurosurgeon. This review has 2 section. For those folks who like bottom line information, please see the Summary. For those folks who like details, please see the Details section. Summary: Dr Daniel Yanni at Disc Comfort is an excellent neurosurgeon who cares about and respects his patients. He will prepare for your initial visit by consulting with referring physicians, if needed. He does not sugar coat information and you will always know the risks involved in your procedure and his thoughts on how to best prepare for a successful outcome. I am walking today because of his expertise and I highly recommend him as a neurosurgeon. Details: I met Dr Daniel Yanni at Disc Comfort in early April 2024 after learning my endometrial cancer returned and it was in my spine. Prior to my first visit, Dr Yanni consulted with my oncologist to start creating a plan for my treatment. At my first visit, he reviewed the scans I brought with me and showed me what was happening with my back. He was very direct about the situation and the risks I was facing. Due to the urgency of my situation, we discussed the best timing for surgery vs chemotherapy. He also recommended additional bone treatments to strengthen my bones and counteract the effects of chemo. Before my first visit ended, I had a surgery date and a list of specialists to see prior to surgery. He allowed me to use a desk in his office to make calls to the specialists so I could setup the appointments. If I was having a problem, he talked to that office to try and help get me an appointment. Otherwise, I was provided with an alternate specialist. He and his office staff were awesome and understood my fear and other emotions on that day. At my second visit, I had not gotten the scans he recommended. I totally spaced on getting the scans but he did not make a big deal of the issue. I knew he wasn't pleased with me and timing was short but he still made sure I knew the importance of the scans and getting them in a timely manner. Unfortunately my back pain had gotten much worse and I was unable to obtain the scans regardless of the pain medication provided by my pain specialist. After trying twice to get the scans and failing due to pain, Dr Yanni ended up sending me to the emergency room the Friday before my surgery so I could be admitted and could be sedated for the scans. During my hospital stay, Dr Yanni's team took excellent care of me and my family. My family was updated during the all day surgery. While I was in intensive care, he kept my family updated and ensured they knew what was happening and why. He also reminded my care team that my new fear of Disney music was due to being under sedation for so long and I did not need a psych consult. He is very logical and knows the impact of everything he does. Dr Yanni and his team were also excellent advocates for me with my insurance. They worked with my insurance and got me into one of the two rehab facilities they wanted me to go to. Anyone who has dealt with insurance knows they can be challenging. Again, I was fortunate to have such strong advocates. Since my cancer was imbedded in my psoas muscle, the nerve root in my L2 and in my spinal fluid, my ability to walk after surgery was not assured. All I can say is that I am walking today and I can climb stairs and this feat is due largely to Dr Yanni and the "A" team he assembled for my surgery and post surgery care. Post surgery and rehab, Dr Yanni has had a conservative approach to my care. He wanted to ensure my wound was healed sufficiently before I restarted chemo. Again, he and my oncologist worked on a plan which has proven to be the correct plan for me. As of today, my PET scan is clear and I'm walking. read more

Dr. Yanni is my number 1 pick for a surgeon. He did 2 back surgeries on me within months of each other and I had absolutely no pain. His office staff is always exceptional. He is so amazing with his after care. He checks on you very often to make sure everything he did is holding up properly. He gives clear directions for you to do after surgery. If you listen and follow his regiment you will heal very quickly and still with no pain. The neck brace wasn't the most fun thing I've ever worn but I made it work. It's all about Dr. Yanni. I wouldn't go to anyone else EVER for back care. There just aren't enough words to describe what an amazing doctor he is! He cares. He really does read more

Dr. Yanni has performed 3 spinal surgeries on me (a partial lumbar discectomy in 2012 and more involved cervical and lumbar procedures in 2023). All of the surgeries went perfectly--they eliminated severe pain and restored full functionality. He came highly recommended as an amazing surgeon and has also proved to be a pleasure to work with. He is realistic and serious (as a surgeon should be) but is also warm and friendly and has a subtle sense of humor. His DiscComfort office staff are also very competent and easy to work with. This is the place to go if you need back surgery. read more

Weird experience. I went to Dr. Yanni as a second opinion, after injuring my neck around C5/C6. I've been in extensive PT since the injury, and have been feeling relatively recovered. I've wanted to see how I could continue recovery, hopefully without surgery. First red flag: 1) The office insists you bring your files on a CD. Fine, that's a pain, but it's obtainable. Second red flag: 2) The office charges you $5 per image that you have on file with them. So, I paid $5 to have an MRI uploaded, and $5 for an X-Ray, because I got those at UCI and not w/in the Hoag system. Seems like a weird cash grab for him to do his job...? Third red flag: 3) I went in, fully expecting to explain what I've been doing for physical therapy, a recovery plan, what we could potentially monitor/do (e.g. would I need steroid shots in the area?), etc. Instead, after briefly examining me for about five minutes, Dr. Yanni gave me two options: - Don't get surgery, and be at a higher risk for severely injuring myself again if I ever got into a car accident or anything, - Get surgery, and get a fusion at C5 and C6. He downplayed the idea of getting an artificial disc during surgery, because it could fail. But a fusion seems permanent for someone in their 30s, who isn't in pain? Fourth red flag: 4) He didn't ask me any questions/get to know my history. E.g. I told him I have more symptoms on my left side, and my PT surmised it's because I have a curved spine, and my left side is weaker. Instead, he randomly asked me if I was a dentist, and said my left side weakness could potentially be an employment issue, and not because of a physiology issue that's pretty obvious? There just wasn't really an effort to get to know ME, and it kind of felt like he just wanted to rush me into surgery. Fifth red flag: 5) He brought in his nurse, to show her my MRI, and was extremely weird about it. He kept conferring with her, when he should have been talking to me. E.g. When he did the patellar reflex test (hitting my knee with a hammer), my right knee jerked. This is not new; both my GP and previous spine specialist noted this. He immediately smirked and looked at the nurse and went, "See?" and didn't clarify to me what was happening. When I asked, he immediately wrote off the reaction as a spinal cord injury, which is not consistent with my MRI. If he had talked to me more, he would have realized that previous doctors have wanted to do more testing, because thyroid disease runs into the family and it could potentially be hyperthyroidism. Long story short: whole place felt weird, and a little cash grab-y. But that's why it was a second opinion. read more

The best Neurosurgeon in the OC. Before I committed to the ACDF surgery recommended by Dr. Yanni, I asked around and talked to several doctors. They all said that he is the best. I am so glad that I decided to go with Dr. Yanni for the surgery. Before the surgery, I was in a lot of pain and could not sleep. The pain went away 2 weeks postop. It has been a year now since and am still pain free. I respect Dr. Yanni's commitment to delivering the best care to achieve the best possible outcome. I would highly recommend anyone who needs spinal surgery to go with Dr. Yanni. read more

Let me start off this review by saying in no way do I doubt Dr. Yannis ability as a surgeon. This review is solely based on how his office operates and what you should expect going into them. I have never dealt with a doctors office who is so focused on making money over patient care. My first office visit I went in for severe neck paid radiating down my right arm. Dr Yanni quickly told me what it may be but I would need an MRI to confirm. He then mentioned it was nearing the holidays so it will be very hard to get an MRI quickly but if I paid his office his concierge fee they would pull strings to get me in quickly (over the course of my two visits I was told about his concierge service atleast 10 times). I said I would take my chances getting an mri for myself as I did not want to go out of pocket so much money to get into an mri quicker. I ended up getting into one same day on my own. I was also told I should wear a cervical collar which I of course was happy to get as it would help relieve some pain and I was told it was $60. After this I went back to his office the next week to review my mri results and he confirmed what he assumed it would be based off my symptoms, a herniated disk that was compressing my spinal cord and nerve to my arm. He then told me he wants me in surgery asap as I would have permanent damage if I waited. I was shown one picture of my mri which looked as if my spinal cord was about to be severed and it was terrifying, of course having no medical experience said ok and he gave me two options of surgery, a neck fusion or an artificial disc replacement. As a 27 year old who knows multiple people who are older and have had fusions I was torn on my decision as they have had many lasting issues since the surgery. Dr. Yanni gave me a two minute explanation then told me to choose what I would like to do. I asked for his opinion and he simply told me it's my choice we can do either. He then stated we should just get something on the calendar for a surgery as it was the holidays but we can always adjust accordingly. I said ok and he said just sign this paperwork so we can start the process. He then once again mentioned if I paid his concierge fee he can get me into surgery faster and get my clearances faster.. This appointment was on December 3rd and he scheduled me for December 17th. After being told it was my decision to make I thought it would be logical to get multiple opinions. The next day I went to another Dr who told me he would never recommend a fusion to someone my age and that he would only recommend someone over 65 get this as it has high occurrence of follow up surgeries 10 years down the line. He told me I should wait about a month to see how my body heals and that it is highly unluckily I would have permanent damage that quickly. I showed him the picture of the mri that Dr. Yanni sent me and we then reviewed all the images of my mri. I was very confused because the images did not look nearly as bad as I had seen, the other Dr stated that the image I showed was by far the worst image and was not nearly as bad as it looked as it was just the angle of the photo that made it look like that. Following this appointment I instantly called Dr. Yannis office and told them we would like to hold off on the surgery for now until after the holidays. I called in and spoke with Amber who told me since the appointment was within two weeks I would have to pay a $750 cancellation fee or a $500 rescheduling fee and this was stated in the contract I signed, mind you this is within 24 hours of scheduling. Of course this is something that was never mentioned to me I was simply told to sign the paper so they could start the process. It is very clear now that they scheduled it perfectly 14 days out so the second I signed the paper I was liable to pay a fee if anything changed. After multiple conversations they said they would waive the rescheduling fee but only if I went to Dr. Yannis personal recommendations of other Drs to get multiple opinions. Eventually we told them we did not want to proceed and they waived the cancellation fee while stating I am only ever able to return to his office if I pay the fine. Fast forward a month I got more opinions and was told the exact same thing I was told by my second opinion that I should definitely not do a fusion and wait to see how it healed. I am now having an artificial disc replacement in the next week. I then received noticed that I had a new balance one month later. Upon opening up the portal I saw I had a balance of $65. I quickly noticed they had billed my insurance $1700 for the cervical collar and owed an additional $65. It was never mentioned to me this would be billed to my insurance nor would I potentially have to pay more. After speaking with Amber about this she chuckled on the phone saying I should have read the fine print and that they would educate their staff. Get multiple opinions as they operate on a don't ask don't tell basis. read more

I have been in the medical field for 45 years and have worked side by side with many physicians. Dr Yanni came highly recommended from within the medical community. I am very thankful that I now have Dr Yanni as my Neurosurgeon. I had severe compression on my cervical spine . He did a vey smooth surgery on me in Sept of 2023 I am pain free and my range of motion in my neck is better then ever!!! He is a very talented surgeon and an all around great guy!! He really cares about his patients. Trust me I know read more

I was a professional athlete competing in motocross for 10 years, and it took a toll on my body. I came to Dr Yanni after being misdiagnosed for 2 years. I had severe sciatic pain in both legs and my right leg would go numb walking around the block. Dr Yanni performed an L5-L4 fusion. I felt relief immediately after the surgery, and was able to stop pain meds in a matter of days. Over a year post surgery I am still feeling great. read more

I went to see Dr. Yanni as a second opinion after being told that I needed an ACDF. The other surgeon was too aloof and cold. I liked Dr. Yanni immediately. He showed me on my MRI why I needed the surgery. I scheduled my surgery that day. I'd suffered from cervical migraines for 20 years (which I was self injecting Aimovig for relief for 5 years ) and had nerve damage down my arm. He didn't make any promises, but I was willing to take the chance. He told me that he was very conservative, and I'd have to wear an Aspen brace for 3 months! I haven't had a migraine since I had surgery! I highly recommend Dr. Yanni! read more

My wife Kathy was referred to Dr. Yanni by another physician for a second opinion. She needed an ACDF surgery on her spine. Making the appointment with Dr. Yanni was the best medical decision she ever made. Dr. Yanni was straightforward and took his time explaining the procedure, what to expect following the surgery and was very patient answering our questions. He is extremely pleasant and friendly. We were so impressed with his manner and his confidence that we decided to schedule the surgery before we left. He was very thorough letting us know what would need to be done prior to surgery. My wife had an unrelated issue with swallowing and he had us scheduled for an appointment with another specialist the very next morning. His staff was friendly and efficient making sure all the clearances and testing were done in a timely manner. We were very impressed with the reputation he has at Hoag. The nurses raved about his talent and stated he was the best surgeon that I could have had and how thorough he was. We are very happy with the surgery. There was no pain at the incision and the surgery has worked. We highly recommend Dr. Yanni. read more

I thank God for Dr. Daniel Yanni. Back in July I had an MRI of my lumbar area due to significant pain in my left leg. My orthopedic doctor diagnosed scoliosis. I asked a friend, who is a neurologist and another who is an anesthesiologist for their opinions of my MRI. Both said they were concerned and said I need to see a neurosurgeon. My neurologist friend recommended Dr. Yanni, and I am so grateful he did. When I saw Dr. Yanni, he noticed that I had other neurological irregularities from his initial examination, and he ordered a cervical MRI because of his observations. When we received the results of this MRI Dr, Yanni said I had a severe degeneration in my cervical areas of C-3/4; 4/5; and 5/6. The degree of injury to the spinal cord was dangerous and I risked further neurological injury, which if not treated now could leave me with permanent nerve damage. He said this issue was far more serious than my lumbar issues. Of course, this scared me. I also saw a pain specialist who did a nerve health test and he suggested that I have the surgery because my nerves were showing signs of significant damage (Praise God for such amazing science!). After consulting with my wife, we both agreed that the risks of surgery were worth it compared to the risks of not doing anything. After meeting with Dr. Yanni to set the date of surgery, we worked with his wonderful staff member (Jasmine) to set up multiple pre-operative tests and other doctors' visits. Dr. Yanni required that I meet with a primary care doctor, a cardiologist, and a neuropsychiatrist to make sure I was ready for surgery. Many of these doctors told me how much they respected Dr. Yanni for his skills and his thoroughness in preparing his patients for surgery. This was all very reassuring news, and though many doctor visits and tests were tiring, I can say I am very glad for all of Dr, Yanni's carefulness from beginning to end of the surgery process. Also, it is helpful to know that Dr. Yanni only does surgery if absolutely necessary. My surgery was at 11am at Hoag Hospital. Of course, my family and I were nervous, but the pre-op went smoothly with the hospital staff. Dr. Yanni checked in with me to reassure me. The surgery took about 4-1/2 hours. After being in the recovery room, I was taken to my room, where I saw my family at about 5:30pm. I was told the surgery was successful and the plan was for me to stay in the hospital one night and be discharged the next day so there would be less risk of infections from the hospital. I was indeed discharged 1 day later after meeting with Dr. Yanni, who checked me and said I looked good. On returning home I was surprised to find that I had only moderate pain and a lot less pain than I expected. I had little pain in the incision area, and moderate pain in my throat, which I was told to expect since the surgery to fix the discs and insert the rods is near my throat. I was fitted with a neck brace which I will have to wear for 3 months to allow for my neck to heal and new bone to grow over the rods. I just saw Dr. Yanni for my two-week check-up where he examined me and removed my dressing from the surgery. He said I was doing remarkably well, and I that I just need to be sure to stay on course with the careful lifestyle he recommends as well as wearing the collar daily. I will continue to follow up with Dr, Yanni for the coming year. Then, if my lumbar issues continue to cause me pain, I will not hesitate to have Dr. Yanni treat me as needed. I hope this review will help anyone seeking a neurosurgeon to consider Dr. Daniel Yanni. God has gifted this man greatly, and I highly recommend him if you have needs for neurosurgeon or spine surgeon. read more

I am shocked to see how many great reviews are for this office. If I could give a zero star review I would. From my first appointment the office was a mess and everyone was running around in circles. Nobody had the answer to my simple question. I gave them benefit of the doubt that they were having a off day. Unfortunately as I continued to make my appts they referred me to it was nothing but problems. I guess a "surgeons" office can't get prior authorization for the imaging script they gave me. Even though, my insurance and the radiology department both told me over and over she should be able to get the CPT code because they are the office which gave me the imagining script. I had a three way call between the office manager (christina), the insurance and the radiology department separately where each time Christina spoke over everyone talking, acting rude, only caring about how "She isn't going to let anyone speak badly about her office." ... sadly it's her making the office look poorly, not anyone else. Without my suggestion, the radiology department and insurance company both submitted complaints based on her behavior and attitude. I have wasted hours and weeks just to get a simple MRI / X Ray because of her. Do yourself a favor and let this review be the longest time you spend on this drs office. If you do choose to go anyway, the only small hope in there is Michelle. She was always sweet no matter how difficult the situation was. Unfortunately all higher problems get pushed to the office manager where the problems start escalating. I wouldn't trust this dr on surgery on my back if their office can't even do a simple prior authorization for MRI imaging with a cpt code WHICH THEY RECOMMENDED. read more

I walked into the office and immediately noticed all the accolades for Dr. Yanni in Orange Coast Magazine! He is what one calls a Drs Doctor. What I really like about him is that he educates you and does NOT push you to surgery. I really enjoyed talking to him and have a return appointment already! I feel so fortunate to have found him... read more

Rude, uncaring, asks questions, attitude about what I had was decided before I walked in, he was walking me out before I knew it. He asked me to walk, soon as I started he asks me if I had a tick? I'm thinking who asks that? Especially knowing I had spinal cord damage and I was paralyzed neck down. I would rather have Trump as my surgeon than have this Dr touch me. At least he thought he looked sharp in his Armani suit. Maybe ? I usually speak my mind but I promised the dr who recommended this so called Dr with God like attitude i wouldn't. I've sat and listened to his video and felt good. After I met this Dr Yanni I assume that video was done when he was humble. He lost his way. Lost soul. I feel sorry for him and the staff , those work for him. They were nice. I hope they will learn from him... which is not to be like him. read more

Who wants Back Surgery? NOT ME! I was in shock when I learned I had Severe Spinal Stenosis. Thank goodness my brother (a retired physician ) recommended Dr. Yanni. It was truly my lucky day! Dr. Yanni was meticulous in getting testing to evaluate my situation. I am beyond happy to report my surgery was completely successful! Dr. Yanni is a gifted neurosurgeon! He gave me my life back! I will be forever in your debt Dr. Yanni! read more

I was referred to Dr. Yanni in December 2019 after exhausting all prerequisite treatments (chiropractor, therapeutic massage, and physical therapy) without any relief for my pain and numbness. At my first visit, I was impressed with Dr. Yanni's professionalism, knowledge, and thoroughness in evaluating my condition. Before making any recommendations, he ordered additional testing and referred me to a pain management doctor for an EMG of my arms and legs and epidural injections. He also made a referral to a rheumatologist to conduct a bone scan. On my second visit, Dr. Yanni informed me I needed both a cervical fusion, C4-6, and a lumbar fusion, levels to be determined, to address my issues. We agreed that we'd address the cervical issues first and I had surgery in June 2020. When I was in the hospital, I remarked that my sore throat was minimal and I was not having swallowing problems like I'd read about. The nurse responded, "That's because you have Dr. Yanni!" That was a year ago this month. I've recovered well from this surgery. I trust him explicitly. He has recommended postponing the surgery on my lumbar spine as I participate in treatment for my osteoporosis. We are just now beginning to discuss lumbar fusion surgery in the near future. Again, I am impressed that Dr. Yanni is not rushing to do surgery but, rather, is concerned with my physical well-being first and wants to make certain my spine is in a condition to withstand the procedure. Remarkable! Last, Dr. Yanni's office staff is just as awesome. They always greet me with a friendly smile, are helpful, and take the time needed to answer any questions. Thank you all! read more

DONT GO HERE I should have read the other reviews. I also should have gone with my gut after my initial visits. The office staff (besides Michelle) are not only rude but incompetent. This office cannot obtain and upload simple radiology documents or images for their clients in a timely manner. They called me the day of my appointment to let me know that they did not have my images (which I got done 2 weeks prior) and then told me I can either do my virtual appointment (to discuss the images they don't have) or cancel and pay the same day cancellation fee. They have no problem wasting your time and/or burdening you. I hope one day you're able to get your "stuff" together. I won't be back. read more

Some Dr's are good, some are bad, but some are exceptional. Dr Yanni is exceptional. Dealing with patients he is caring and super professional. I'm impressed not only for his knowledge but also for how much he care and how perfectionist he is. I'm very happy with him and can easily recommend him. read more

Dr. Yanni - WOW!! Thank you so very very much for giving me a life I never had before. I wake up every day feeing the sensation of endorphins rather than pain. I look forward to my new more active life, rather than a wheel chair. Dr. Yanni is very thorough and made sure other possible causes of my pain were ruled out before planning surgical intervention. Less is more with Dr. Yanni, so we focused on the area of most pain deciding on spinal fusion of L2-5 and C 3-5. He also uses minimally invasive techniques, which is a HUGE factor in faster recovery. Instead of months (9-12 as estimated by other Drs using traditional large incision techniques for lumbar fusion), my recovery was well on its way within 2 months. I was working from home, walking the park without a walker or cane. I experienced very few of the potential risks and side effects of the surgeries that were explained could happen, and those that did resolved in a few weeks to a month or so. 12 months out, I hardly remember the recovery. I truly feel 30 years younger; my new spine is wonderful. The hand of God works through Dr. Yanni. I have recommended him to many of my family and friends and give him the ultimate platinum highest recommendation. read more

My surgery was on 1/9th. All I have to say is the care I have received, both pre and post opp surgery is phenomenal read more

Well I finally had surgery on October 8 at Hoag Hospital in Newport Beach. ACDF 3-levels. C5-6, and T-1. Lead by this amazing surgeon I happy to say that everything went very well and I'm home on the mend. A little discomfort with back pain, swallowing, soreness, nausea, but no actual pain at the incision. Just the normal symptoms associated with major surgery. Happy to report that Dr Arie Gluzman, Pain Mgmt specialist in this same office, got my symptoms under control quickly. He's another highly qualified professional in this group. In truth everyone associated with Disc Comfort Inc. is professional, friendly and caring. Especially Christina the office manager. This busy office could easily become hectic and chaotic if not given her talent for managing people and processes. She rocks! Friendly, warm and efficient, imagine that. Good luck read more

Excellent surgeon for anyone with a spinal condition needing surgery. Cervical myelopathy and stenosis is serious, so we did research and learned a great deal, before moving forward. The first surgeon we saw, wanted to do immediate surgery. Dr. Yanni was our second opinion. After thorough evaluation and considering the MRI, he suggested additional nerve tests. So we had those tests and got a third opinion, returning to Dr Yanni. Good thing we did, because he is definitely the best of everyone with whom we spoke, discussing all options. Once we decided, his staff acted fast, to schedule at Hoag Hospital. My GF checked in at 5:30am, surgery went from 7:30am to 11:20 am as scheduled. Dr. Yanni had a great team, performed with total professionalism, reviewed the post-op CT Scan, and everything was a go result..!! Was awake and talking with good arm movement, right away. etc. There's throat swelling from the impact of the intubation and so it's No solid foods. Only Smoothies, thick soups, etc. at least a week or two. Our post-op Nurse Kelly noted that Yanni does things a bit differently than other doctors, ordering more conservative post-op treatment and release from hospital ASAP. Well recommended, we will return. read more

Doctor Yanni is nice BUT, I sensed it right away the moment he saw me, the first question was, when do you wanna get this done? Wait...you're not even gonna let me go through a step by step procedure first like therapy, shots, chiro or whatever etc. You just wanna cut me up like that? Well...that right there made me sense it's all about money! Dollar$, Dollar$, Dollar$! Guest what guys, I am so glad I didn't fall for it. One year later all my pain and numbness went away! I knew God had a plan for me. Moral of the story is, go with your instinct, and most of all don't jump to quick getting a surgery as that's what most greedy for money OTHER doctors do. Not all. It's so hard to find a doctor that really cares for your well being. read more

Loosing my ability to move, use, or strengthen my right hand/fingers and my hand overtime becoming a claw was a scary ordeal that lead me to an MRI, a refferal and a visit to Dr. Yanni. I had a herniated disc on my C6-C7 causing me to slowly loose my motor skills. My hand was the first to slowly go. My first appt. I immediately felt like I was in good hands. From his warm welcoming staff and Dr. Yanni's friendly demeanor he put me at ease right away knowing he was my doctor. I went into this scared, nervous and unsure. After doing my research on my type of surgery, my doctor, and the risks vs partial/full recovery, I knew he was the right doctor to help me and my situation. I had an anterior c6-c7 partial Corpectomy (anterior due to the type of injury, location of the herniated disc and my age, 30) with a c6-c7 spinal fusion. I had surgery in March 2021 and spent less than 2 days in the hospital. Post op is never easy and the first three months were some of the toughest days, I won't lie. Having a good support system, friends or family to help with the small tasks is highly recommended. The beginning weeks were hard, emotional, physical, mentally, but it does get better and easier and the pain becomes less! I was on a thickened diet the first few weeks (due to the anterior approach through the front of my neck) and a neck brace 24/7, and daily walks when I felt good until July. In July I was able to no longer be in a neck brace and In August I began small PT for my neck along with PT for regaining function in my hand. Post op, there was good days and bad, I had to eat, sleep, and be in my neck brace at almost all times as my fusion of my c6-c7 healed. As the months have progressed I have NO pain in my hand or neck and can move my neck in all four directions with no pain.(If I tweak my neck or do something I shouldn't to irritate it I might have a slight painful few moments but nothing that is constant.) I've been lucky enough to have almost zero to no pain after surgery with my hand function 90% recovered! My herniated disc caused my nerves to be compressed for almost a year before I finally saw a doctor. I highly recommend not waiting to see your doctor, the sooner you find out what is wrong the faster you potential can heal and fully recover those damaged nerves. We are now 10 months post op, no pain, 90% function of my hand, and The incision where my surgery was is hardly noticeable! I am completely and truly forever grateful for Dr. Yanni and his team of amazing individuals. He took the time to get to know me, teach me, and change my future for the better, while communicating honestly and genuinely. If I had to do it all over again (I would have gone in sooner), and I would absolutely trust Dr. Yanni and his team with my whole life again. I now am living a pain free, no longer a claw hand, and avoided potentially ending up in a wheelchair for life. Thank you from the bottom of my heart for everything! read more

Dr. Yanni and his staff were incredible to work with. The level of empathy, professionalism, and knowledge of Dr. Yanni and the kindness and professionalism of his staff were exemplary.

I found myself on the doorstep of Disc Comfort in June 2019 following an unenviable diagnosis of thoracic osteomyelitis (Google the definition). I had no previous spine injuries or surgeries. My spinal condition was a result of having cancer several years prior which left me to manage lymphedema and repeated cellulitis blood infections. I was referred to Dr. Daniel Yanni at Disc Comfort through the pain management office of Dr. Arie Gluzman. During my visit to Disc Comfort, I was impressed with Dr. Yanni's approachable demeanor, his willingness and patience to answer all my questions and most importantly, his extensive spinal surgical experience. My case would require thoracic vertebrae fusion of T7-T8, fabrication of a new disc using bone fragments and marrow and reinforcement of T4-T10 with plates and screws. After hearing this prognosis, like any consumer I sought out additional medical opinions to help calibrate the procedural options. The surgeons I met with were impressive however, Dr. Yanni had the edge. He was confident in his surgical capabilities (without the ego) and came across more "invested" in the outcome of my overall health and well-being. This gave me greater peace-of-mind as I prepared for a pretty scary surgery! I'm almost 90 days post-surgery and doing great! I had little to almost no pain throughout the process and am wearing a (not so sexy) brace and bone growth stimulator to assist in my recovery. My overall impressions of Disc Comfort: Office Staff - Elizabeth and Kristina were friendly, accommodating and efficient throughout the process. Dr. Yanni - Approachable, compassionate, confident, highly endorsed by his medical colleagues, a surgical expert (magician) that you want on your side. Likelihood to recommend Dr. Yanni - Absolutely!

I was referred to Dr Yanni by my chiropractor. I came to Dr. Yanni with a L5S1 disc extrustion, extreme pain, numbness, and a drop foot. Dr Yanni is amazing. His knowledge and surgical skills are unmatched. He explained in detail what was going on with my disc and what my options were. From the minute I "walked" into his office to the day I walked out of the Surgery Center, Dr Yanni and his staff have provided me with the highest level of care. I can't say enough! I am so thankful to have found Dr. Yanni. I am only 8 weeks out but pain free and symptom free. Thank you Dr. Yanni. read more

Due to my experience, I recommend getting a second or third opinion if Dr. Yanni recommends cervical surgery or even retesting in 6-9 months. So glad I did as I am not in need of this high risk procedure. read more

In late 2019 (Age 57) I developed lower back pain radiating down my right hip and eventually more down my leg. Around March 2020 I gave up and went to see my primary who sent me to get an MRI which revealed that I had a synovial cyst and some disk bulging at L4-L5. There was also other degeneration at L3-L4, but L4-L5 was the target for now. I was referred to physical therapy for several months as a first step to try to provide relief. It was a good try but didn't work except to strengthen my core. Surgery became the only option and my PT referred me to Dr. Daniel Yanni. Dr. Yanni sent me for various other tests like nerve conduction in my legs. He talked to me extensively about my choices (My non-technical descriptions); 1. Remove the cyst and clean up between L4-L5 or 2. Remove the cyst and fuse the L4-L5 joint. Dr. Yanni advised on both and let me decide what I thought was best for me. I decided after careful consideration that I could go back for fusion if needed. In November of 2020 Dr. Yanni performed option 1, minimally invasive surgery removing the Cyst and creating some extra space for my nerve root. The scar is less than 3/4" and faded now. Recovery was just a few months with minimal pain after a few days. I was off pain meds quickly. With some additional PT and now fast forward to August 2021 and I am pain free most of time. I have lost some weight and continue to work out as I was taught in PT., I don't take unnecessary risks with lifting but I can lift most anything I need to. It's emotional as I write this last part because I though my normal activities were over for life. The pain became depilating and now I am back to normal. Thank you Dr. Yanni and a big shout out to Nurse Michelle for her professionalism, kindness and support. read more

Dr. Daniel Yanni equals Perfection. He is extremely caring for his patients, very calm and listens to everything the patient has to convey. Both my wife and myself found his analysis spot on and very comforting and we both felt that we were in the best hands. Post surgery, we were provided instructions and he had informed us what to expect. However we had a few questions on what my body was experiencing and we were expecting to leave a message for the doctor and him to message back, however Dr. Yanni immediately attended the phone and provided all required information which put us at ease. He and his entire team have been absolutely great from the start to finish i.e. prior to surgery, during surgery and even post surgery. He recommended us to a great pain specialist as well for further treatment and physical therapy to avoid reoccurrence. We are so thankful to him and his entire crew. As much as we hope we don't have to go for another procedure but if we ever had to do it, then it will only be with Dr. Yanni. read more

Dr. Daniel Yanni is a superb spine surgery. He performed two surgeries on my spine - neck and lower back - at a point in my life I thought I would not be able to walk normally again. Not only I can walk normally but I'm pain free and looking forward to exercising again. He is not just a physician. He is a scientist ahead of his time that uses his knowledge and top notch technology to help people. He also has a great smile and takes pride on seeing his patients' recovery. I'm truly happy with my new spine! read more
