I've been a patient of Dr. Treyzon since 2014, a year where no Gastroenterologist would "dig deep" enough to find out the root of the problems I was having. No other Doctor has shown the amount of care I have received from him, and still do up until this day. When you don't know what's happening to your body and you have fear of the unknown, having a Doctor that has great communications skills, treats you accordingly, and has amazing bedside manners is the most important tool you can have in order to overcome a health situation. I'm forever grateful for crossing paths with Dr. Treyzon and his amazing staff.

Dr. Treyzon, Leo, is probably about the best doctor I've ever received care from. The operative word is "care", which was immediately apparent from the my first visit. I cannot emphasize enough how smart he is, how companionate he is, what a great communicator and caregiver he is. Anna and Amie on his staff are made from the same "stuff". Think of it, you don't feel well, you don't know what's wrong, you need someone who can help you find answers and give you comfort and peace. I promise you, they listen, they care and they over communicate! I've lived it with Dr. Treyzon for almost two years now. I feel so lucky to have him as my doctor. Thanks Dr. T.

I’ve only had an initial consultation, but was impressed with Dr. Treyzon’s compassion, the time he spent with me and the information he shared regarding what could be done about my situation. He was very professional and affable and I left his office feeling in time I would be feeling a lot better with him as my doctor.

Dr. Treyzon and his assistant were wonderful to work with. They spent a great deal of time with me, listened intently to all the details of my long history with SIBO/IBS-c, and looked over the many pages of medical information I brought in.I felt they were very thorough. They answered all my questions, and Dr. Treyzon even returned my follow-up call to him with-in an hour of me leaving a message!! He has an easy on-line message system where he can communicate with his patients. He's extremely accessible, which I truly appreciate. I'm already seeing some positive results from a medication he prescribed!

I've seen dozens of doctors over the course of my lifetime, and Dr. Treyzon is hands down the most empathetic one I've met thus far. He not only is extremely intelligent, but also is incredibly innovative, and constantly looking towards the most novel methods of diagnoses and treatments, whether they be pharmacological, surgical, etc. Additionally, he is also extremely timely in regards to his email responses, and to that same point, possesses exceptional communication skills. The end product is excellently delivered healthcare, and so you will absolutely be satisfied if you entrust him with your GI care.
