"I had an amazing experience with Dr. Michael Madievsky at Unio Specialty Care. Right after the staff took my blood pressure, I didn't even wait two minutes before the doctor walked in. When a doctor opens the door with a warm smile, you automatically forget all of your stress! He took the time to explain everything from A to Z about what to expect leading up to my colonoscopy. Thank you, Doc, you really are the best!"

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)
