5 out of 5 stars

This was my first visit with Dr. Duncan, and it was truly a 5 Star experience. From my arrival at the office to my departure I was treated courteously and efficiently by the staff. Dr. Duncan listened to my concerns and took the time to explain and illustrate possible causes. He was caring, informative and comforting.


Dr. Duncan has been in practice since 1997 when he joined the Hartford Hospital Medical Staff.
