This was my first colonoscopy and not high on my bucket list of things to do. They were very professional and made you feel very comfortable with the hole procedure. From the office staff to the nurses in the procedure room, they were all simply awesome.

My mother has to see Dr. Tanenbaum for her first colonoscopy recently and him and his team made it so easy for her to handle. She was very worried and stressed with the procedure but Dr. Tanenbaum has such a vibrant personality and makes it so quick and easy to understand the process. I love how exuberance and the care team’s diligence with helping my mother before, during and after the procedure. Would highly recommend!!
