Having a colonoscopy is not something I look forward to, but the entire staff made the process easy and as pleasant as it could be. Due to the recent ice storm they were a little backed up and I was still out of there in about two hours. Dr. Rives came to talk to me before and after the procedure and was willing to answer questions. The entire staff made the procedure as pleasant as it could be.
