"Dr. Rufner is the BEST! He took a lot of time during my appointment to explain my G.I. issues and devised a plan for treatment and further testing. I found him to be patient, caring, knowledgeable, and thorough. I highly recommend him for any G.I. issues. He is far and above other G.I. doctors, I have seen in the past."

"Dr. Trouillot is a very knowledgeable doctor with a caring professional bedside manner. He listened to everything I had to say and made me feel comfortable talking about gastrointestinal issues. He made me feel like we would find out what was wrong with me, and did not, at any time, make me feel “gaslighted”. I would recommend him without any reservations to anyone needing to see a gastroenterologist."
