Dr. Dai has done my colonoscopies for the past 17 years. I had a major problem this past spring, and he was one of the few doctors who looked beyond the pictures to evaluate me as a person. His personal intervention got me transferred to a more comprehensive facility immediately, and provided me with an analysis that made me question what other doctors were telling me. I would be alive today regardless, but I am completely functional thanks in some part to Dr. Dai. All of my doctors cared, but he treated me as a whole person.
