I saw Dr. Nassos for a disability evaluation of my right knee. I have been seeing doctors for the past 4 years about my knee, pre- and post-surgery. The difference between seeing Dr. Nassos and the other doctors is that you can tell he still cares about his patients! He asked me some questions and gave me his medical opinion of the status of my knee. He also answered questions I had on next steps, as I am still in constant pain. As a first-time patient and a nurse, I found Dr. Nassos to be professional, knowledgeable, and caring. He is easy to speak to, and I only wish that I had met him before my surgery. I would definitely refer other friends/family members to him for their ortho needs. read more

Disgusting treatment of new patients, why waste people's time? Hard if not impossible to get in touch with anyone, so fell free to get disrespected! read more

Dr. Nassos is the BEST, couldn't have asked for a kinder, more attentive and professional doctor to take care of me. And gosh have I had my share of incompetent (read factory chain offices), rude with no bedside manners and yell at me doctors because I dare to ask questions and want to understand what the surgery entails. I wasted 3 months with one Dr. who ended up closing shop (due to some legal issues, escaped that one narrowly!) and another month looking frantically for a new doctor and coming across one who was so old school, he yelled at me for daring to speak and ask him questions... no names shall be named (but PM me if you want to know). What a relief to have found Dr. Nassos! Not only does he take more than 5mins to sit, examine and answer all your questions, he always has a comforting smile that puts you at ease. I needed that especially since it was my very first surgery, and was a total nervous wreck. The night after surgery, I had to reach him and totally appreciated getting a call back within the hour late at night. And he even took the time to call in a prescription at the nearest 24-hr pharmacy. Post-op appt. went well, he removed sutures, went over some deets and off I go to focus on recovery, physical therapy and physiotherapy for the next 6 weeks until the next follow up appt. If you are looking for an orthopedic doctor you can trust and who really cares, I'd highly recommend Dr. Nassos. read more

This office is always impeccably clean, the staff courteous and polite. The bathrooms are consistently tidy. My only recommendation for the ladies' room is to have a small table where we can place our purses while we wash our hands. The general waiting area is most accommodating, refrigerated water a selection of freshly brewed coffee, espresso or tea beverages of your choice. Additionally, there's a variety of snacks to enjoy. I particularly enjoy the vanilla latte and peanut butter pretzels. Dr. Nassos is always extremely pleasant and professional. I highly recommend this office. read more

Today was my first appointment to see Dr. Nassos and I'm so glad I did! The office in Pomona was easy to find and the office staff was so helpful and professional. The Doctor was very courteous and took time with me to answer my questions. Dr. Jonathan Nassos is one of the best Doctors in Los Angeles. I'm very grateful for his staff for a smooth visit. I highly recommend this office in Pomona, Ca read more

LA is the type of town that has some of the best doctors in the world. The problem is, it's such a massive town that finding them is like searching for a sharp needle in a haystack of dull incompetency, undeserved arrogance, and vanity. I'm lucky to have met Dr. Nassos, because he's that rare hard-to-find breed of doctor who is intelligent, incredibly skilled, and personable. He was formally a partner at a very prestigious practice in Chicago, and moved out to LA just recently after spending time working as a doctor for the Lakers. Simply put, the work he has done for me is nothing short of a miracle; I have only felt compelled to write reviews for two doctors, and he's one of them. The fact I was even able to see him I can only chalk up to fortuitous timing, because I'm sure in about 5 years as he gets settled here, he will grow more and more popular to the point that it will be impossible to even book an appointment with him! For the time being, however, I was able to see him right away, and he was attentive, thoughtful, and extremely, extremely capable. After completing a procedure with him, I can say confidently that he has done what no doctor before him has been able to do. I'm not exactly sure what else he treats, but if you're having any knee issues (as I had), there is no better doctor than Dr. Nassos in Los Angeles to work with you from start to finish and take care of your problems. read more

My experience was great. Allow me to explain: I was at work, did something stupid and blew out my knee. Man, the pain was excruciating. I couldn't walk. I literally heard a popping sound and practically had to crawl to my car. It swelled so bad I thought I'd need knee replacement surgery or orthoscopic surgery, laser surgery, a polygraph, something! - I dunno, whatever the hell it is they do that's what I needed. I couldn't walk! My mother n law refers me to Dr. Nassos. Now, I love my mother n law but quite frankly the prospect of her choice scares the hell outta me. I figure I'm gonna lose a limb and pay through the nose. But I schedule an appointment anyway. Deep breath. After all, I hate doctors' offices. No, I loathe doctors' offices. So, I hobble to Dr Nassos office in Sherman Oaks and at first was really impressed with the environment; a large and roomy waiting room, and a very friendly staff. Plus they pretty much took me right away. Huge points right there. The examination rooms and the décor inside is great and instantly put me at ease. (did I mention I was having anxiety) This is no stuffy doctor's office but rather something out of Restoration Hardware. Wood floors, leather chairs... I liked it very much, and then it got better. Dr Nassos comes in. I real young-looking dude, warm and friendly, very professional, and as nice as can be. Seems to really know his stuff. He puts me at ease immediately. (In fact, I had read a previous review bashing him and it was SO off the mark that I went back to it and clicked on the name to see the "author's" OTHER reviews. Sure enough EVERY review written by that person was some one-star scathing diatribe. A true malcontent. I'm glad I dismissed them). Whoa, big digression. Where was I? Oh yes, Dr. Nassos comes in and sees the panic on my face. After all, I was never going to walk again, right? He gently feels around on my knee and sends me to the next room for xrays. They come back quickly and are unimpressive. Apparently, I have some laxity in my ACL, quite common, not debilitating, and the worst part about it is I've been exposed as a big wuss. After some reassuring words Dr Nassos recommends an MRI to be sure, and frankly, I appreciate the attention to detail. His office was very helpful helping me set up the MRI. Also, his office takes Blue Cross/Blue Shield and my out of pocket for the office visit was like a 25.00 copay! After a few weeks of adhering to Dr Nassos instructions of using a knee support, icing, resting, and slowly stretching, etc., I'm all good, up and about, and the only thing still bruised is my ego. I'd recommend him anytime. He really put me at ease and helped me fix the problem. Thx Doc. read more

I was referred to Dr. Nassos by a friend, and I am so glad I took her advise! He is a great doctor with compassion and empathy. Its rare these days to find a doctor who will take the time to LISTEN, (i might have vented a bit) lol. Thank you Dr Nassos for the great service you provide everyday. read more

Dr. Nassos is exactly what you want from your surgeon. As smart as it gets and meticulous with his work. He is very knowledgable and this is obvious every time you speak to him. The best part is the surgical center he operates out of is top notch. Immaculate, clean and very private. Highly recommended he gets my two thumbs up! read more

I was recommended to Dr. Nassos by a friend & it may be the best recommendation I have ever been given. I have been to numerous doctors for my knee pain and they all said the same thing...wait as long as you can and then have a knee replacement. I am in my 40s and was also told that I would need a second replacement if I got it now. Previous doctors told me to take ibuprofen and hang in there. Dr. Nassos is the first orthopedic surgeon to offer me an alternative treatment. He told me about injections that I could receive in my joints to help alleviate the pain. I opted to try it and my pain was gone. I will still need a replacement eventually, but in the meantime, I don't have to be suffering. Dr. Nassos listened to what I had to say, spent time with me explaining my options in a way that made sense to me and followed up with me to make sure I was okay after the injections. I 100% recommend Dr. Nassos. He is an excellent doctor!! read more

Dr. Nassos is Great!! I would highly recommend him. He is an expert at Orthopedic surgery, he has great bedside manner, he genuinely cares about his patients, he listens to you, and will go above and beyond for his patients. Thank You Dr. Nassos read more

Dr. Nassos is an amazing orthopedic surgeon! He really spends a lot of time and goes out of his way to help you out! He listens carefully to his patients and has wonderful bedside manners. He explains the injury, treatment options, and answers questions very clearly. My daughter and I had a wonderful experience! read more

Thank goodness for Dr. Jonathan. I was in so much pain due to a knee injury and he was able to help me after the first visit. He is intelligent, kind and really knows what he is doing. I am also so pleased that his plan for action did not involve medication. Every doctor I've seen in the past just wanted to prescribe something for the pain but that left me exhausted and depressed. I highly recommend Dr. Nassos to my friends, family and the Yelp community. read more

I had a ankle fracture and I when in with an another orthopedic to get treatment and he told me it was only a sprain. I found out about Dr. Nassos from a friend of mine, his a really great doctor. Once I came in to his office they did an X-ray and he say that it was a fracture. He took good care of me his professional ,prompt ,nice his just the Orthopedic your looking for to help. I would highly recommended him to all my friends and family. read more

Outstanding Orthopaedic Surgeon. Explained the procedure that was he was going to do. Very caring Doctor. Would recommend to others. Very knowledgeable and checks on you after surgery. read more

Dr. Nassos is excellent! After dealing with shoulder, back and neck pain for years and being bounced from one doc to the next, Dr. Nassos quickly and efficiently helped diagnose my issue and put me on the path to recovery. Not only that, but he took the time needed to listen to my concerns and make me feel totally comfortable with my options - a rarity in my experience! Now, six months out from shoulder surgery I feel the way I've wanted to for years! Having seen more than my fair share of Orthopedists over the years, I couldn't recommend Dr. Nassos any more highly. If you need an ortho, this is the guy! read more

Wonderful doctor! He took his time with me, explained in plain terms what my condition was/is, and, instead of taking the opportunity to do X-Rays (which I was prepared to shell out for), he treated me right on the spot and I've seen a major improvement. It's my belief that Many doctors would've done X-Rays anyway, even if they know the situation doesn't warrant it or it's completely unnecessary. The fact that he spared me from this absolutely floored me. He also suggested that surgery was not likely necessary and, being an un-insured patient, this was incredible news. I may still have to have surgery, but it won't be because a doctor wanted to rush in and out of the room and just "get it over with," thus leaving me with the easiest and typically-acceptable solution. Dr Nassos sincerely took time with me, has a great personality, and really knows his stuff. I wouldn't hesitate to go back to him for further needs. read more

This was - quite literally - the single most impactful medical appointment of my entire life! Somehow I tweaked a tendon, nerve, or some other piece of scaffolding that gets REEEEEAL grumpy when it feels mistreated in my upper right back (an odd place for back pain for me). The pain was persistent (I felt it 100% of the time regardless of my position), and quite intense (I was able to go about my business, but had it gotten one notch worse, I don't know what I would have done). Worse, I was on a 9-day business trip to SF, LA, and Burbank from NYC, so I lacked access to my normal caregivers. I went to a very good urgent care in SF where they injected me with an anti-inflammatory and gave me Valium (! apparently it's a muscle relaxant) but unfortunately that did nothing. Ice, rest, and multiple OTC anti-inflammatories and two prescription ones did nothing. In desperation, when I saw I had a 4-hour gap between my last meeting and my flight out of Burbank, I booked Dr. Nassos on ZocDoc (I had feared it could easily take weeks to see an orthopedist!) He is EXTREMELY warm, attentive, easy-going, and UTTERLY knows his stuff. He examined my back thoroughly and efficiently, then gave me a different injection and a different prescription (a more "real" muscle relaxant) and sent me on my way. His wonderful staff hastened things as they knew about my flight. It's now the next day and my back is 90% better and improving rapidly. After a week-plus of mysterious, acute, and worsening pain this is a boundless relief. Almost as bad as the pain was the helplessness I felt to do anything about it, and my fear of what might happened if it got only a little bit worse. Dr. Nassos told me that he tries to leave a few appointments clear & available on ZocDoc every week, even though he has a very busy practice, to be available to folks just like me who find themselves in a sudden, urgent situation. This is an incredibly generous public service (as I'm sure some of these last-minute appointments must inevitably go unfilled, depriving him of revenue), because it IS very hard to get on a good orthopedist's calendar. If there was a sixth-star option on Yelp I would definitely give it! read more

I came in to see Dr. Nassos a couple of months ago to get a second opinion on my lefty knee that I had surgery on about 8 years ago. Dr. Nassos was incredible to identify what the problem might be options as far as moving forward to rehab my knee and avoid further injury. Just recently I came back to see him with a sprained ankle and once again extremely helpful as well as experienced to guide me in the direction to heal from the injury. read more

As I guy in my 30's I like to keep myself in shape and remain active. Well, during a men's league soccer game I felt a pop in my knee and was down for the count. I found out that I had torn my ACL and needed surgery to repair it. I was referred to Dr. Nassos and knew from the start that this was the right Doctor for the the job. Sports medicine is his specialty and since he has worked with the Lakers, Kings, and Dodgers, I figured that was good enough for me. The experience was as pleasant as could be considering I was going under the knife. He is very informative and educated me on the diagnosis, surgery and what to expect that all of my fears were soon gone. The surgery was a breeze and with some physical therapy my knee feels as good as new. Hopefully I never have another need for Dr. Nassos' services but if I do I know I will be in great hands. read more

Dr. Nassos has been my doctor for a little over a year now. He has done everything in his power to help through a very difficult year. Dr. Nassos took care of me and helped me when I needed it the most. He is an excellent doctor with a wealth of knowledge. Dr. Nassos actually gave me faith that there are still really wonderful doctors out there. His approach and how he works with his patients remind me of the good ol' days of medicine. You can really tell that he cares about his patients. I am only one of many that he has helped, but I am certainly grateful for being referred to his care. The other great thing about Dr. Nassos is that if you have an issue that falls outside of his specialties, he will make sure to help you find the best care he can. Although I live about an hour or so from his practice in Van Nuys, I would continue to come to Dr. Nassos for any future orthopedic needs. I feel so blessed to have had such wonderful care and I recommend him to anyone with orthopedic issues, he is one of the very best! read more
