Wonderful Care
Dr. Treyzon is providing me excellent care, comprehensive knowledge and he takes the time I need to discuss and understand the road to bettering my gut health. I am so glad to have found him and highly recommend.

Outstanding experience
Dr Treyzon is first rate. Referred by my internist for tests, i found him to be smart, friendly, accessible and communicative. His staff is well organized and efficient. His web site and videos also helped explain procedures and reduced any anxieties. The experience was quite positive and I highly recommend.

Don’t go to this doctor if you have SIBO. He lacks experience and training.

After seeing countless doctors with no explanation to my GI symptoms I decided it was time to find someone who could actually help me. That is how I found Dr. Treyzon. I would definitely recommend him to anyone with a complex GI disorder. Dr. Treyzon is extremely knowledgable. He will take the time to listen to you and help you. He will set up a game plan and make sure you are not alone in the process. I have nothing but good things to say about him and his staff. He is definitely the best!

Hate writing bad reviews but this is justified and I want to contribute to the COVID fund you are promoting. No I would never refer this Dr to family or friends. I paid 500.00 cash for my appointment. He was dismissive of my concerns, which caused me to lose a lot of weight - asked “why does it bother me;”that many people would like to “be like me.” He tried to backtrack when I expressed my surprise that he did not understand my feelings. Told a friend about my bad (and expensive) experience with him, and she told me a client of hers did not like his demeanor with her as well.

Dr. Treyzon is a fantastic physician. After months of poor treatment with a different doctor, Dr. Treyzon was able to quickly diagnose me and provide treatment. As I continue to work with Dr. Treyzon, he has taken the time to answer all of my questions and concerns actionably - within or under 24 hours through the elation passport website - and think about the future development of my gut health. I cannot recommend him enough and have been telling all family and friends with gut issues to see him. Erudite and a class act.

I don't understand how can this doctor sleep at night. He is "out of network" and charges $650 for "initial consultation"!!!! This is immoral and plain wrong! Doctors are supposed to help people and they made an oath to cure people not to get rich from them! Shame!

During our consultation Dr. Treyzon asked me questions that were both intelligent and thoughtful. I most valued in him were 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.

Avoid at all costs ! First off they charge new patients $650 for a consultation upfront! I argued with the receptionist as to why I should pay upfront if I don't know what to expect from the visit. Secondly, the visit lasted at most 30 min with Treyzon, the beginning was with his attendant. He even instructed me to continue with my current care as he does not specialize in my condition when in fact his website states that it's his specialty. I went there to also consult on an appropriate diet but was instructed to read a book on SCD and did not receive any explanation on the matter; something I can do myself by simply typing on a Google Search. For those writing that he is a miracle doctor and giving all these 5 stars reviews please message me and I will redirect you towards the real 5 stars GI & IBD doctors. I've had my fair share of doctors to know who are deemed to merit these accolades. I've been part of clinical trials for some of today's mainstream medications to know a thing or

My visit with Dr Treyzon was fantastic. His office is ran very efficiently and the staff are friendly and helpful. Dr. Treyzon himself was great; he was very clear, succinct and laid out a clear road map of my treatment. He was easy to talk to and I felt comfortable with my treatment plan when I left his office. I also really like how I am able to communicate with Dr. Treyzon through his messaging portal.

My GI issues started when I was 14. That was 20 years ago. Over the years I have been to numerous physicians and GI docs. Dr Treyzon is hands down the best GI Dr I have ever been to and probably the single best Dr I have met. He has helped me treat SIBO, an ulcer, and called in numerous favors with a number of specialists when I had unexplained liver enzyme increases for a month and spent a week in two different hospitals. He is at the top of his field, & yet has a humility and bedside manner

Dr. Treyzon's front office is disorganized and irresponsible. The person who reviews insurance information and office forms/policy neglected to tell my son of the $400 out-of-pocket fee the doctor charges before the initial appointment. A $400 consultation fee is absolutely outrageous, especially when not informed of it prior to arrival at the doctor's office.

Dr. Treyzon has incredible expertise, and is an exceptionally thorough physician. His approach is to treat the whole patient - not just the symptoms. He is a physician who always thinks through all the possibilities, does all the necessary tests, and listens to his patients. He is VERY responsive, and you are never left waiting for results, or a call. His staff is on top of it, and he always makes himself available - despite his busy practice. Our whole family sees him - we are so lucky!
