Patient Reviews
Jan 25, 2021
Over the last decade, I have seen GI doctors at some of the finest NH hospitals, but none of them did what Dr. Detweiler did for me in the first visit alone. First, he read my comprehensive medical history carefully prior to our meeting. He didn't think only about GI but about my health overall. He then educated me about the GI system. He listened to me describe my symptoms, and believed me, never rushed me and helped me shape the picture of my health. No other GI doctor I have been to has ever approached my health is this way. He is one of the wisest doctors I have met in my life.
