This was my first time with Dr. Madievsky. I have a colonoscopy every year due to a genetic condition and I had to change doctors due to scheduling issues.
Dr. Madievsky specializes in my genetic disorder, has great bedside manner, friendly and available. The only thing that kept me from giving him five stars was the fact that his office didn’t call me when I was told they would to confirm the time and slso to give me the bowl prep instructions for the Sutab (he doesn’t use that method to prep, and that is the method I was used to, so there were no instructions readily available for me)
