I found Dr. Treanor to be very knowlegeable and caring. He made sure I understood everything that was going to happen. He is very patient, friendly, and talented person!

I found the entire colonoscopy experience about as enjoyable as anyone could imagine for such a procedure. I was well informed from the the 1st day of contact several weeks ago right up until the lights went out from the anesthesia. Your staff was very prompt and most courteous. My wife was appreciative of the manner she was treated and especially the promptness. If asked, I will speak highly of you and your facility.

This Dr is very caring and takes the time to listen to concerns and explains things very thoroughly so that I can understand.

Initially it took awhile to get scheduled, but once that was done the staff and providers were great. My procedure was exactly explained well and completed swiftly and efficiently. Just waiting for my results. A+++ service
