Very thorough. Answered questions completely. Anticipated questions. He does talk very fast, however. That and the mask made it a little difficult to catch all of what he was saying. Doesnâ€™t change my recommendation. Still great.

I first went to see Dr. Nealis to get a second opinion, because the doctor I originally went to couldnâ€™t explain why I needed to have another colonoscopy in 3 months. He just continued to repeat the same thing, even though I said I didnâ€™t understand. Dr Nealis was able to explain why in a manner I understood, I still had to have another colonoscopy; actually had 2 more, but understood why each one was necessary. Dr. Nealis answers all my questions and listens to my concerns.
