I am a primary provider myself, and I have to say that his knowledge is on the leading edge in the field. I felt confident in his plan and comfortable with his professional manner.

It was my first time to see Dr. Madievsky. He showed greater concern for my heart issues than my previous G.I. specialist. I had no idea of the possible dangers of having a colonoscopy without considering my pace maker. He chose to test my stools first and then get a colonoscopy if something shows up in the sample. I trust him 100%.
