Dr.Santharam has been my GI Dr for several years now. I am an Aurora patient referred to Pro Health by a friend, with a situation that I needed a different perspective on. He is very thorough responding to your concerns quickly with avenues to be administered until he can see you.His office staff, the best! I trust him with my health and his commitment to it!

The office staff at 1111 Delafield were friendly and helpful, they scheduled my colonoscopy with Dr. Santharam. I received prep instructions through the mail in a timely manner, and they were easy to understand. Two days before the procedure I received a call from RN Sue (very nice) about the procedure. Day of, I forgot the name of the nurse who started getting me ready (sorry), Nick and then Sue, they were great!! Made me feel relaxed. Dr. Santharam is a very good MD, communicated well and nice bedside manner. He is so on top of things that I went back for procedure 30 minutes early!
