Dr. Dever is very knowledgeable and professional. He takes the time to talk to you about the exam and after the procedure he spoke to my wife about the results in detail. The procedure was painless and happened quickly. I am very happy how everything went and highly recommend Dr. Dever for your next exam.

He was over 1 hour late and gave me 9 minutes of his time. Did not feel I got what I needed out of the visit.

Extremely focused on my G.I. problems. Excellent at explaining test results and discuss discussing treatment options. In my extensive experience, the best G.I. doctor I have ever seen.
