The worst experience I've ever had with a MD!!! He completely missed diagnosed me for years while o was paying lots of money. And when after years, years of struggling I was diagnosed by another physician and told him that, instead of being kind and supportive he started scaring. Stay away from this doctor. He come across very nice and professional but he had the biggest ego. read more

First meeting with Dr Treyzon was fantastic. He was exceptionally thorough, and better than any other physician I have seen in LA. He does not take insurance, but he's reasonable to get into and see, & also the wait was no more than 5-minutes. Time is money. He is also very respectful & likes to educate his patients. I wish all my Dr's were like him. read more

Not sure where the negative reviews come from?? Leo is great! I've been seeing him for years. Wouldn't go anywhere else. He's quick to respond, his staff is efficient, he's transparent with treatment and pricing. Can't find folks like him these days. 6 stars! read more

Dr. Treyzon prescribed me Cipro for SIBO, which caused fluoroquinolone toxicity, tendonitis, and neuropathy in my arms and legs, which is likely permanent. Dr. Treyzon did not disclose or discuss the black box warning from the FDA that comes with taking this drug Cipro with me when he prescribed it. When I messaged Dr. Treyzon about my condition developments, he never responded to me and ghosted me completely as a patient, which seems unkind at best and unethical at worst. I messaged him 2-3 more times, expressing my concern that he had never responded to my message, where I asked him to please warn future patients that he proscribes this medication to of the FDA black box label and I never received a response from him. I waited months to see if he'd respond with any care, advice, or compassion before writing this review, but he has not. Dr. Treyzon will treat you with kindness until he makes a mistake then he will inappropriately and unethically leave you to deal with the negative developments of his treatment on your own. To be ghosted by a doctor you're looking for advice and compassion from is deeply revealing and utterly disappointing. Hopefully this review leads you to seek a second opinion or to take a second thought before trusting Dr. Treyzon unequivocally. There are much more caring, ethical, and considerate doctors as my almost 3 decades of dealing with doctors, combined with my personal experience written here makes evident. Dr. Treyzon also does not take any insurance and charges extremely high prices for any additional testing or bloodwork, which his office did not provide a superbill for, despite my repeated requests. Please heed this warning. read more

Dr Leo Treyzon sets the bar very very high. He's a brilliant diagnostician,is held in high esteem by his peers, and is a perfectionist in the OR. Cedars was rated number 2 hospital in the NATION for GI Dept, that was when he was the chief of Dept. 2017-2018. He also is warm, kind and likes to decipher a complex case. He diagnosed me with MCAS, I had been sick for my entire life. Mayo missed it, everyone else just treated me for their individual specialty . Dr Treyzon looked at me not just as a GI case, but as a patient with a complicated history. This is his super power ! He went all out to help me, spoke with numerous other Drs, found specialty labs to do a test usually only done at Mayo or Brigham and woman's hospital in Boston. He's a very rare breed, intellectually gifted and a true healer. I know Dr Treyzon well, he took care of my elderly father with compassion. He is worth waiting for. If he is unsure about an issue, he will tell you. But by next visit he will be almost an expert. I rarely trust anyone but I trust, respect and like him without reservation. Wendy read more

During our consultation Dr. Treyzon asked me questions that were both intelligent and thoughtful. I most valued in him what I was least expecting from a hot shot Cedars specialist: being that his office did not work w/ my insurance provider, he was extremely considerate in ordering just the amount of tests I needed and preemptively told me ways I could get pricing information. He was not condescending, he was in no rush, and more than happy to answer all of my (million) follow up questions right then and there. The testing processes could not have gone more smoothly or rapidly. I was diagnosed (w/ what he had suspected) about 48 hours later. The doctor took additional time to research some of my past symptoms and share useful results w/ me. His office referred me to a phenomenal pharmacy that helped again w/ insurance, and in the following days the doctor patiently--and immediately--fielded all my follow up questions through the online portal. All in all totally outstanding. read more

We haven't even met this Dr yet..,and will not! We made an appointment for a telehealth appointment that would cost $700.00! (30 min call)! We had to put down a 200.00 deposit and forfeit it if we could not keep the appointment! Absolutely disgusting! We HAVE the money.. probably more than he has... but it's all about principal. A Doctor who took the Hippocratic oath and isn't abiding by it.., all about the money I don't care how "fabulous" this MD is... not accepting Medicare with a supplemental Insurance ... limiting his patients to concierge... is despicable. Dr... call yourself a "concierge" MD... Because that is what u are We have a Primary care physician who is a Concierge... we pay her yearly for that service... and she still takes our Insurance ! You should be ashamed...! read more

Quite disappointed with my two visits to Dr. Treyzons. Upon second visit, the doctor was late and distracted. He suggested that my digestive problems were due to anxiety or "organic coffee" and sent me off. The digestive tests we did were sent to the wrong office and I had to wait two more weeks to find out that I was diagnosed with giardia. The folks at the front desk said they did take my insurance, yet I was still billed $300 per visit, a year later, finding that they 1-wouldn't take my insurance and 2-wanted me to pay directly. For such an expensive doctor, I was hoping for more assurance, attention, and help. read more

Dr Leo is a great Doctor. Has a lot of Knowledge and he truly cares to give you the best advise about your digestive system. Yes it is expensive but honestly when thinking about my gut I rather pay. There is some issue with insurance, that I don't much get it. I wish that was better handled. He also combines some natural remedies and knows a lot about healing foods. One day after coming back from a trip to Los Cabo. I got food poisoning they advised all sorts of antibiotics really harsh, and I took them for a day, feeling awful, arriving in LA he said I think you already got rid of bacteria and he explained why, I also got some lab work and he reviewed it and said: Don't take them any more as they are affecting you instead of helping I did that and got well in a few days read more

I booked a consultation with Dr. Treyzon to explore if I may have SIBO that could be exacerbating endometriosis symptoms. Although he appeared to be very intelligent and up to date on the medical literature relating to SIBO, I chose not to work with him because I found him extremely patronizing and arrogant and preferred another doctor with a more holistic approach. "Maybe you have an education problem" was his response to me when I politely refused his recommendation to simply take birth control for my pain - but I did not want to spend any more time during that $700+ appointment explaining why I felt his recommendation was a shortsighted ineffective choice for my body (or that maybe he has a women's health education problem?). That being said, I found his staff to be pleasant and organized and the intern who did my intake was very thorough and compassionate. In a nutshell, Dr. Treyzon appears to be competent in his specialized SIBO practice area with a methodical approach to treating it, but his bedside manner needs some work. read more

CAVEAT EMPTOR- BUYER BEWARE! I'm posting this review to relate my personal nightmarish experience with respect to Dr. Treyzon's questionable billing practices. Hopefully, it will serve as a preemptive cautionary tale to prospective patients to be alert to this office's nefarious business tactics. Here's my story: I made an appointment, via phone, for an office consultation with Dr. Treyzon, prior to scheduling a colonoscopy. His office manager, Aimee Kim, stated that Dr. Treyzon did not participate in my insurance network, and that I would be responsible for Dr. Treyzon's fees ($250 for the office visit, and $1100 for the procedure) both of which I paid for, up front. At the time of the office visit, Ms. Kim stated that, "as a courtesy" the office would bill my insurance, and forward the reimbursement to me. Cut to the chase- In reviewing my insurance statements, I discovered that Dr. Treyzon had been reimbursed by my carrier IN ADDITION to collecting his fees from me! I've called his office numerous times, and spoken to his assistant, Dalia, who offered a multitude of responses (including the time- worn" the check is in the mail " excuse). I contacted my insurance carrier whose various representatives have also received the run-around. Failing to attain any resolution, my insurance carrier initiated two grievances against Dr. Treyzon. As I have not received reimbursement of MY MONEY, my insurance company has referred my case to their fraud department. I, in turn, have filed a complaint with the Better Business Bureau, seeking reimbursement. Whether mere negligence/ ineptitude by Dr. Treyzon's staff or willful illicit business practices, double-dipping is never acceptable. We Seinfeld fans can attest to that! read more

I came here last year and got a stool test and blood work done. They were out of my insurance so the appointment alone was $400. Dr. Treyzon was sexist, rude, arrogant and unhelpful. Not only did I find out after the stool test that I was just inflamed which I already knew they didn't even give me my blood type after the blood work. All in all this one appointment with this unhelpful doctor cost me over $1000 to basically get no answers. Waste of time. I will not be back and I do not recommend this doctor to anyone. Thank goodness for this Korean acupuncturist that I went to. He was $300 and gave me more advice on how to held my stomach pain than anything Leo ever recommended. read more

Dr. Treyzon is the most thorough doctor I've ever met. Not only did he completely fix my acid reflux and digestive issues, but he diagnosed another problem that wasn't even GI related. Other internal medicine doctors couldn't even pinpoint the issue and Dr. Treyzon figured it out. Multiple ER visits and weeks of pain without an answer and 20 minutes with Dr. Treyzon and I had a treatment plan. Within a day I'm feeling better. Incredible top-notch care! He is brilliant, compassionate, truly committed to his patients. I am seriously so grateful he was put in my path. I would be suffering and probably in the hospital without him! Truly an answered prayer. Seriously. Thank you Dr. Treyzon for all that you do. You are absolutely incredible! read more

He told me the procedure would be covered by my insurance, and then later sent me an exorbitant bill. When I disputed it he sent it to a collection agency that jacked my perfect credit. I would not recommend this doctor. read more

Dr. Treyzon is an incredible gastroenterologist. I had had stomach problems and pain for three years. I saw multiple specialists, but no one helped. Then I saw Dr. Treyzon. He read my lengthy history and even asked for more information. Afterwards, he had me do common sense tests others had overlooked. He was extremely thorough. Based on the results of my tests, Dr. Treyzon went down the list of rational treatments until he finally found one that helped. He was determined and patient. I now feel much better. It's remarkable. Because of Dr. Treyzon, I can eat without pain. Dr. Treyzon is also the most responsive doctor I've worked with. He replied immediately and thoughtfully whenever I messaged him. Dr. Treyzon is a great doctor and a kind person. I highly recommend him. read more

Dr. Treyzon is by far one of the very best physicians in Los Angeles. He is completely devoted to his profession and his patients, and he is excellent at what he does. I feel fortunate to be one of his patients. He had treated me once for intestinal issues and when I called back--maybe a year later--in intense pain, he went above and beyond to help. It was after hours, probably 7:30 at night--and I was in excruciating pain. Dr. Treyzon asked me a series of questions; he and I were concerned I would not be able to wait until the next day for medical attention. He said, meet me at my office. I can get there by 8. My husband and I met Dr. Treyzon at his office--he had driven in just for us at 8 at night! He thoughtfully examined me. My pulse and blood pressure were very high, and I was quite week. Dr. Treyzon said I needed fluids immediately and a CT scan. He phoned the Cedar Sinai ER and let them know to expect me. He even wrote out his recommendations--for me to hand the ER--in terms of pain medications (I have some allergies) that would both ease the pain and level out my BP. The ER staff was so impressed by Dr. Treyzon having met us after hours and call on our behalf that they seemed to think we must be VIPs in some way--not realizing that Dr. Treyzon treats all of his patients like Very Important People. I have to say they took impeccable care of me. It was the best ER experience I have had--which seems like a strange thing to say, in that no one wants to be in the ER, but I felt very well cared for at a time when I needed it the most. Dr. Treyzon continued to interface with the ER doctors throughout the long night and into the wee hours. He was very concerned and caring and extremely thoughtful. Having gotten through the worst of it that night, I was better but not well, so Dr. Treyzon scheduled an upper and lower G.I. endoscopy. I was scared to get put under, but the procedure went very well. Dr. Treyzon took several tissue samples to biopsy--he was extremely thorough. I am feeling well again! Dr. Treyzon and I emailed back and forth--he takes the time to answer all of my questions. I was so impressed by Dr. Treyzon. He practices medicine not only with the technical expertise and thoroughness--but he also does so with a great degree of compassion and an absolute devotion to his patients. I can't thank Dr. Treyzon enough. But I can certainly pay it forward in sharing my experience, so that anyone in need of an EXCELLENT gastro dr. can have the absolute best level of care! I don't believe even the President of the U.S. gets better care from his doctor! Thank you, thank you Dr. Treyzon for practicing medicine like an art! read more

Can't say enough about Dr. Treyzon; he literally fixed me in 3 days! I've been experiencing extreme bloating and distention for months and always thought it was something else. Turns out I just needed to be on the FODMAP plan. He is easy to talk to - you meet in the comfort of an office, not an exam room. He took the time to really speak with me; I felt validated in what I was experiencing. And after all that, he even called to check-in and see how I was feeling - even making a referral for a family member. 10 STARS if I could! read more

I could not have been treated with more disrespect and lack of compassion for my medical condition than I was at Dr. Treyzon's office. I was made to wait over an hour for my appointment after having arrived a half hour early with all my relevant medical records and my new patient information having been sent to his office ahead of time. More significant--is the fact that considering my appointment was due to severe abdominal cramping and other pain associated with colon issues there was all the more reason that I should not have been made to wait any longer than necessary. At the very least I might have been offered an examining room to lie down in for more comfort. The staff made no attempt to offer me any apologies or explanations. His assistant expressed annoyance from being bothered by a patient when I asked how much of a delay I could expect after having already waited 45 minutes. She conceded Dr. Treyzon had not been delayed by an emergency. When Dr. Treyzon took me to his office an hour + after my appointment time, he didn't even bring up the fact that he was running behind by any acknowledgement or apology and when pressed by me for any accountability, was arrogant and patronizing. I felt so lousy physically, that I just decided to move forward with him. However, he couldn't seem to move past it as he made several references to how I might be better suited to finding another doctor. Finally, when he was unable to locate my blood work (which his assistant had confirmed to me she had received from my ob/gyn beforehand,) I was on the same chart with Dr. Treyzon that he wasn't a good physician for me. He offered to make some referrals. At this point, thanks but no thanks! I left with more angst in my gut than I came in with! read more

Great Dr ! Helped with my acid reflux. Answered all of my questions. Great staff. Replied to my questions at MIDNIGHT! through the elation passport communication app. I see everyone complaining about the cost on here.. there shouldn't be a price tag on your health read more

Dr. Treyzon is one of the only doctors I've ever met that truly listens to his patients and doesn't give up on figuring out what's wrong. He also isn't your typical 9 to 5 doctor. He's called to give me test results at 8pm and on a Saturday. Highly recommend him. read more

After seeing several different Drs I found Dr Treyzon and he was so kind, so knowledgable and so thorough that within five days of treatment my symptoms started to go away! I can't say thank you enough for giving me my life back. I can not recommend Leo Treyzon enough! read more

Dr. Treyzon is simply the best! I have been seeing Dr. Treyzon since 2009 for various chronic digestive issues. He is without a doubt the best GI I've seen. He is genuine, kind and personable and most importantly, a fantastic physician on the cutting edge of medical research. Dr. Treyzon is warm and empathetic. He always follows up with labs and monitors my care very closely when I have a flare-up. I am aware that others have complained about the cost of his care, even with insurance. Great care costs more. Period. Dr. Treyzon is as good as it gets, and I think the visit fee is reasonable considering the caliber of his care and knowledge in the field. Dr. Treyzon actually goes out of his way - as do the people in his office - to make sure that medical testing and prescriptions are covered by insurance. He also goes out of his way to refer me to the best physicians for other types of care - such as nutritional care, obgyn, etc. It is comforting to know that I have Dr. Treyzon in my corner in light of how complicated access to good medical care has become - even with excellent insurance. In conclusion - great care costs more. To argue with that is to be in denial of what has become of the medical field in this country, especially in California. Dr. Treyzon is a specialist who really knows his stuff and has helped me a great deal and I feel grateful and blessed to be his patient. P.S.: Some of the tests I have had with Dr. Treyzon include a colonoscopy/upper endoscopy, PillCam test and blood tests - which take place in his office through an outside lab provider that takes my Blue Shield PPO. Very convenient!! And parking tip - if you're not in a hurry, park at the Beverly Connection to save $$ because the Cedars parking lot is very pricey. read more

The first time I met Dr. Treyzon, I was blown away. Clearly part of a very busy practice, I thought I'd get maybe 5 minutes of his time to quickly try and explain to him what was going on with me and determine a strategy on how to move forward. I couldn't have been more wrong. He sat across from me asking questions and gathering information with a laser-focus on my health and me. I never felt rushed and was astounded by the amount of time he spent with me. He took time to explain everything and the genuine concern I felt coming from him put me at ease. He had just met me and yet I felt like getting me to feel better was his top priority. Since that first visit, he came up with a diagnosis and treatment plan that has served me well for the most part. The part that hasn't is self-inflicted because let's be honest....who wants to do the FODMAP diet for the rest of their life?!? Half my favorite foods are on the elimination list! My company also changed insurance 3 times since I started seeing him and his assistant Amie has been so helpful in determining my coverage and letting me know what to expect. There's a real desire on their part to get me the best medicine for the most affordable price. In fact, when one of my insurance companies denied the very expensive antibiotic I needed, they put me in touch with another pharmacy that helped me to obtain the medication needed through an assistance program...and they delivered it to my home. Amazing! It hasn't been a smooth road in the year and a half I've been seeing Dr. Treyzon as there have been additional developments with my health. His unwavering support and concern have been proven over and over by his availability to me at all hours, and always with such a calming influence. He answers his own emails and always much more quickly than I would expect anyone with a practice the size of his to be able to do. I honestly don't know how he does it, but I'm grateful he does. This must be what it feels like to have a doctor in the family...and at the end of the day, isn't that type of care we all hope to get?!? Well, look no further because that's what you get with Dr. Treyzon and his staff! read more

Well so far so good. The whole staff was amazing and was quick to get in once I showed up for my appointment (maybe 5 min wait). The intake DR or resident did a full breakdown of all my issues so Dr Treyzon was well informed when he walked in and he definitely looked over my forms I sent in early because he already knew my background which was AMAZING. How many Dr's make you fill out all your history but then just ask you everything again because they didn't look it over? He took a lot of time to explain everything and was super knowledgable and didn't waist time going over all the info in my sheets I filled out already and went through all my tests on cedars app before hand. I hope it all goes as planned but so far I can say without a doubt that this was a 5 star experience. The plan has been laid out so I hope for the best but feeling great about it. read more

Dr. Treyzon is amazing. His office is warm and inviting. It does not feel clinical, nor does it make you feel like you're going to see an "almighty doctor." Dr. Treyzon asks about the whole body, lifestyle, diet, as well as the problems. He's up on the very latest cutting edge research and has no problem breaking it all down. He's open to discussing alternative remedies and referring when necessary to people with more specialized training such as dietetics. I felt listened to and valued and I am so happy to be under his care! read more

Best Gastro Dr. in Los Angeles Wonderful compassion for his patients, excellent diagnosis,calm, amazing bedside manner, really knows his stuff, easy to chat with and extremely thorough in every way possible. This is a GREAT DOCTOR !!! read more

My client had been given a G a tube due to aspiration pneumonia , she would have had it the rest of her life . Her friend found that Dr Treyzone was a very highly rated gastro Dr. we went to see him, he said if she could do certain things she could get it removed . There were quite a few things she needed to do first , she did them and the G tube was removed . She has been off for several years and she is doing great. She is 84 yeas old . Without Dr Treyzone she would have been still been Sporting the tube. read more

Never thought I'd be reviewing a colonoscopy, but somebody's got to do it. Long story short: Dr. Treyzon made pleasant a most unpleasant situation. I knew he was the guy when after I said, lying on the table, "You know, there's nothing I like better than being in a clinical environment and having my narcotics administered by a licensed professional", without missing a beat he says, "You mean, we're supposed to be licensed? Uh oh..." Great doctor. Great crew. Cannot recommend more highly! read more

had a colonoscopy with Dr. Treyzon and his staff. Dr Treyzon was very thorough with his explanation to me and had a very nice bedside and caring manner about him. His staff of michelle, Maryam and Dr Thom the anathesiologist where are great, helpful and caring as well. read more

Dr. Treyzon is by far the best doctor I've ever met. I live in Rochester, New York and have had debilitating GI motility issues/pain for over five years. I traveled across country to meet with Dr. Treyzon. He LISTENED to me for over an hour, ordered several tests, found undiagnosed issues and prescribed new meds all in 2-3 days. He follows up regularly to inquire about my symptoms and offer further alternatives/options for improvement. His approach is methodical and thorough. If one thing doesn't work he tries something else. He won't give up on you. He genuinely wants to help and is highly dedicated to his patients. I would give him 10 stars if I could. I can be reached at vickiruff62@live.com for further inquiry about my experience. read more

said diet didn't matter when it came to my stomach symptoms? got charged so much money despite having great insurance. nothing was resolved, i'd suggest going elsewhere read more

This is strictly for appointment making process. I went on website and filled out all information and waited for a response. Never got one so I called and left message still never heard back. While I was told Dr. Treyzon is a great doctor he should have a more efficient staff that makes an effort to call his potential patients back. read more

I can't say enough about what a superb physician Dr. Treyzon is! I have consulted him for some difficult and perplexing problems that have confounded other doctors. He is always highly attentive and very empathetic, really listens, and takes the time to answer all of my questions. He is also readily available through their messaging system. Recommendations for diagnostic tests or referrals to other specialists are always handled quickly and efficiently by his staff. read more

By far, the best doctor I've ever met. Dr. Treyzon spent 2.5 hours with me today, eager to figure out my prognosis. This comes as a relief after 5 years of many painful and exhausting symptoms that no other doctor fully understood. Dr. Treyzon ordered a variety of tests to assess 4 different possibilities, all of which he explained to me thoroughly so I understood why each test was ordered. I did not feel like he was trying to make more money off me, rather he was genuinely interested in my symptoms and truly cared about me. Never have I met another doctor who is this comprehensive with patients and truly cares, and for that I'm eternally grateful! His staff is incredible too - rare find. Kudos to Ana for her patience, taking notes for me to take home so I could listen to the doctor and focus on understanding my symptoms. 100% rockstar team! read more

I couldnt even make an appointment, because the secretary was so difficult to communicate with!

Buyer beware, or more like "new patient, beware." I made an appointment three weeks out for Dr. Treyzon and when the receptionist called to confirm my appointment, she also told me that "there is a one time annual ADMINISTRATIVE FEE of $150." I didn't think I heard her correctly so I asked her to repeat it. Yup. An administrative fee. Obviously I canceled the appointment on the spot and now I have to source a new doctor and wait even longer to be seen. His office should have warned me about this "fee" when I was making the appointment in the first place. He may be a good doctor, so I can't speak to that, I'm only posting with regards to his charges. That deserves a one-star rating. read more

Let's just start off by saying, if I could, I would give Dr. Treyzon 10 stars!! Which is why I was so surprised to see a few reviews that were less than perfect. I then realized, as a business owner myself, people usually like to use social media and review sites for negative comments. You rarely find people willing to take time out of there day to post positive reviews. So here's my experience: For about 5 months specifically, I have suffered from major symptoms that left my active lifestyle nonexistent. I was in and out of the ER multiple times and sent to many specialists in the San Diego area. All the doctors I was referred to were a disaster! None these doctors were listening to me, my symptoms and the hell I was living! After dealing with the mess of trying new doctors waiting for appointments and each doctor prescribing me random antibiotics for issues they didn't really know I had. I was left being exhausted and losing hope of figuring out what the real problem was. I then was referred to Dr. Treyzon through another doctor (my internal medicine doctor in LA, she raved about this young, amazing GI specialist). I drove to LA with all my medical records and about 2 pages of symptoms I was experiencing for the past 5 months. He sat down with me and listened to EVERYTHING...(which I admit is a lot and would drive any doctor crazy). We came up with a few recommendations for other specialists I needed to see ASAP. Within a few days I was on my way to start testing for underlying conditions. I have to say with the help of Dr. Treyzon I accomplished more in 4 days then I had in 5 months of being miserably sick! (For the record, all my bills thus far have been processed by my insurance and I have not had a problem with any insurance or billing issues. Nor did the staff make me feel like I needed to pay an obscene amount of money for the service I was receiving, which is way more then I can say from other doctors I have seen in the past!).... During this time we have solved my GI issues, which I have been dealing with for years! I just finished my upper endoscopy yesterday and have completely retired my prescription antacid medication that I have been on continuously for 3 years... Thanks to Dr. Treyzon I figured out I never even needed to be on it! I have to say, I'm probably the biggest baby and scared out of my mind to take any medications, have any procedures and do anything that has the potential of making me feel any sort of pain. Dr. Treyzon and his staff made me feel so comfortable, less nervous and actually excited to figure out what was going on with my stomach. After being so sick for the past 5 months I pretty much have turned into a worry wart, borderline hypochondriac and am so so thankful for Dr. Treyzon and his staff for their continued email communication and quick responses to my crazy and frequent emails and calls! (I'm kinda thinking this guy never sleeps!). He actually himself has called to follow up with me, which is amazing! He has also saved me a few times from more pointless ER visits. I cannot express enough how amazing he is! If you're really looking for a great doctor who knows his stuff, willing to listen and pay attention to you, get to the bottom of things and do it with a great attitude I would highly recommend Dr. Treyzon and his staff of professionals to anyone. I have really felt welcome and noticed my health was a priority to him and his staff. read more

Dr Treyzon is an amazing physician and an incredible person. He truly cares about his patients and it shows!!! My father and I have been patients of Dr Treyzon for over 9 years now and couldn't be happier. I felt hopeless with my GI issues and he gave me hope again! He takes his time, listens, and does a thorough exam. He incorporates both traditional and holistic medicine into his care. An incredibly knowledgeable doctor who is up to date on the advancements in medicine, is compassionate, and follows up with care...he's truly wonderful and I'm so lucky to know him! read more

I have SIBO (small intestine bacterial overgrowth) and when I went to see Dr. Treyzon as a desperate last attempt at getting a GI Doctor's help. Not only did he not seem to believe what I was telling him I was feeling but he tried to tell me this might be a problem I will have forever and should see a therapist to accept this is "my new body shape." He told my Naturopath this was a "cosmetic case" meaning it's me being vain and not being happy with a bloated belly and that it's MY issue. I can't believe I wasted $400 on that visit because it made me feel defeated and furious at the western medical system. If you have a straight forward stomach issue maybe he's fine but if it's anything beyond his realm of training, he will make you believe it's not a real thing and it's all in your head. read more

I am a physician in Los Angeles, and I have seen Dr. Treyzon as a patient. I am consistently blown away by his compassion, intelligence, patience, and thoroughness. He always has time for my questions, and he always follows up to see how I am doing. In addition to being a great doctor, he is a caring and sweet person. This leads to him having a very busy practice, but somehow he manages to balance it all. I have had to wait for him, but I have had to wait for every doctor I have ever seen. It's the nature of the business. I know that I am receiving 100% of his attention when I see him, and I never feel rushed. He I have recommended him to many friends, and everyone agrees he is just lovely. read more
