Best doctor I have ever been to. He has it all: knowledge, kindness, efficiency, judgment, and most importantly, he gave me hope that I would get better. I am still being treated by him as we methodically follow his plan for healing. His portal email system is so helpful and eliminates misunderstandings. If you have a GI issue, I would only see Dr. Treyzon.

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!

I have known Dr. Treyzon for 8 years. He took care of my daughter when she was hospitalized and had GI complications after spinal surgery. He was really helpful and warm in our moment of need. We were so impressed with him then, that the whole family started seeing him. My husband, daughter, and I have all had procedures without any problems. it was a nice experience, as good as that can be. Dr. Treyzon is one of a kind in that he listens to my own perspective and my preferences for how to addre
