What People Say About Dr. Mary Sine, MD
I had gone to Dr. Sine for many years, and left merely because I had moved out of the general area. After seeing a doctor that was closer to my home, I decided to return to Dr. Sine's practice, even though it was a bit further away. She remembered me well, and welcomed me back with open arms. She is very easy to talk to, informed on the latest medical information, caring, and very down to earth. I will continue to recommend her to anyone.
