How likely are you to recommend Dr. Gronowitz?

(Select your rating)
This was to be my second colonoscopy. Wait time for the office was only about ten minutes. My consultation visit was relaxed and he answered all my questions and the procedure was scheduled. I happened to be the first that day. The staff was boom boom, checking me in, prepping me, etc. I was wheeled in the room on time and Dr. Gronowitz was there all ready. When I woke up, he came over and told me the results and took another few minutes to answer a question or two I had. I was out of there in no time. Everything went like clockwork. I would give this doctor TEN stars if I could!
