My first colonoscopy and Dr Treanor made me feel very comfortable and his explanation of what was going to happen was spot on

J.H. Google

Good discussion of my symptoms or concerns. Spoke faster than i would like, but did further explain when asked to elaborate. Very difficult to get an appointment for initial meeting. Phone rang over 4 minutes on multiple attempts to schedule initial visit. Staff were helpful and pleasant.

D.C. Google

I was very pleased with how the procedure went and what the outcome was.

I.B. Google

Dr Treanor was courteous and was willing answer any and all question.
