How likely are you to recommend Dr. Markus?
My husband had been sick for months. He was going through many tests. The waiting lists for an appointment were long throughout the area. With his doctor's help he was able to squeeze him in. He was very nice, very friendly. He called me into the office after he preformed the procedure. Doctor Markus explained the results very well and he really cared. He took many samples of the biopsy. He was sure it was cancer. He listened well to our questions and answered them well. The very next day he called us himself to give us the the bad news. He is professional, friendly and really nice Doctor. My next colonoscopy I will be going to him. I highly recommend him to anyone.
