Wonderful, attentive, world-class doctor! Dr. Treyzon always makes me feel comfortable and cared for plus the office is really lovely.

Dr. Treyzon is the best Gastroenterologist out there! I mean this! I had my first visit with him after visiting multiple gastroenterologists, and the difference is that he truly cares and spends so much of his time. He answers every single question, gives clear instructions and really understands what you the condition maybe. Dr. Treyzon always has back up plans as well. The best Gastro!

Dr. Treyzon is an extremely attentive physician who keeps you at ease. Also, his office is exceptionally organized.

Because of COVID, I chose to do my first appointment with Dr. Treyzon via Zoom. My husband and I were extremely impressed with him! After asking me many questions about my very complicated autoimmune issues, he came up with a plan to determine what would be the best course of treatment. He was extremely thorough and took the time to listen. He's one of the best doctors I have had in my decades of having numerous doctors.

My 1st of many visits I will have with Dr. Treyzon was wonderful. He is thorough, knowledgable and showed attentive care in my goal to get a long term plan in place for my digestive wellbeing. Dr. Treyzon is a diamond in the rough…he is what physcians used to be like in making you feel that you matter and listening to what is important to your health. Thanks Dr. Treyzon!

Dr. Treyzon is one of the most caring and thoughtful doctors. He takes his time, he understands each issue and cares deeply about each of us.

My actual visit with Dr. Treyzon went smoothly, but everything since that date has been awful. First, he said with "almost certainty" what he thought my issue was, which after taking an at home test, proved not to be the case. However, I understand that's the nature of diagnosis. But my reason for leaving a one-star review is that I was misled about the cost and my insurance coverage, then prescribed a test that wasn't covered and ultimately cost me $600. His office then harassed me for months as I tried to explain to them my issues with their billing process, which they continually ignored, until they ultimately hired a collection agency. I don't know Dr. Treyzon personally, and it seems like others had positive experiences, but I found the entire process to be misleading and scummy.

I can't say enough about what a superb physician Dr. Treyzon is! I've 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.

Dr. Treyzon is not only the best GI doctor in Los Angeles, he is unbelievably thorough, caring and meticulous. Within 20 minutes of my examination he had an idea of a prognosis and when the blood tests came through it proved him to be correct. He reached out to me later that evening to solidify a diagnosis and I feel better already. Don’t hesitate to book Dr. Treyzon. He’s the best.

I am blessed to have Dr. Leo as one of my medical doctors.
I have been seeing him for many years and feel I am in the best hands.

Doctor Leo Treyzon Is not a just a wonderful doctor, but human being. Super knowledgeable, no wonders he is the chief for Gastroenterology at Cedars. He is been wise to adequately prescribe medications, probiotics and even pull me off of medications as he is understands that bodies are different and respond differently. My insurance is not contracted still I drive and hour and pay more, it is worth the visit

Dr Treyzon spent a lot of time with me to review my entire history and had a good handle on all the technical details. I didn’t feel rushed at all, which I cannot say about other Gastrointerologists. If you need more confidence in your condition you will get a frank and detailed diagnosis.

Dr. Treyzon truly cares about his patients. Its very comforting to know that you can always email him with questions or concerns, and get a quick response. Dr Treyzon always takes the time explain everything in detail and is very thorough and thoughtful. The office is clean and comfortable. The staff is excellent. Everyone is friendly and organized.

One of the best medical experiences I’ve ever had. His approach is refreshingly human whilst also being medically thorough. He was kind. He’s clearly an expert in his field. I would highly recommend his practice to a friend or family member. I left feeling very grateful.

Dr. Treyzon is a fantastic physician. He is responsive, diligent, and driven to help all of his patients. He is an astute clinician, but, more importantly, he is a great person.

Dr Treyzon is the ultimate professional and has the best demeanor and follow up. I highly recommend Dr Treyzon for all of your GI needs.

Dr Treyzon is a terrific doctor. He carefully explains everything, taking the time needed rather than running to the next appointment. I just wish he could be my primary care doctor!
