Dr. McGuinness is excellent. He is professional and friendly and answers all your questions thoroughly and takes the time to explain any and all concerns you have. I have a rare form of cancer which involved a small bowel resection. I have numerous blockages which Dr. McGuinness monitors closely. I highly recommend Dr. McGuinness! He is the best Colorectal Surgeon around!
