“Dr Kahn and his staff are AWESOME. He is thorough, kind, listens and puts you at ease. The staff are patient and very helpful. I was so afraid of having a colonscopy. Dr Kahn was wonderful. My procedure went so well. It was over and done with in what seemed like a minute! The worst part about a colonscopy is the prep. So expect that! Dr Kahn is excellent, I trust him completely. And I recommend him, and his staff.”
