I was made to feel very comfortable before my colonoscopy. The nurse on site was very accommodating, approachable and easy to talk to. The Dr. came to visit before my procedure and, he, also made me feel at ease. All was explained in lament terms before and after my colonoscopy. I will use this institution and hopefully, along with the same staff, over again. All were very professional and my fear of it all quickly faded to comfort and relief of what was to come.
