An excellent doctor who showed much patience with my many questions. He gave very thoughtful answers. The colonoscopy procedure went very well. He was very professional, as were all of the staff members at Duke.

I saw Dr. Zachariah for a second opinion on a borderline gastroparesis diagnosis I was given by another doctor. Dr. Zachariah confirmed I did in fact have gastroparesis and spent a lot of time with me answering all of my questions and going over the various treatment options. He did not seem rushed like a lot of other doctors. The front office was also extremely efficient, as I only had to wait a few minutes to be seen. My only complaint is it took 5 weeks to get an appointment, but I think that's pretty standard for a specialist, especially during COVID.
