Dr Cohen has been my GI dr for some years now. He is an excellent clinician, knowledgeable, timely, thorough and concerned. I highly recommend him to anyone with GI issues.

My wife and I had colonoscopy screenings with Dr. Friedlander. He is a warm human being and excellent physician. He and his staff made the experience very comfortable. Many thanks!
