Having an injury was not as bad as it could have been with Dr. Coran and his staff. Dr. Coran took the time to make me feel like I was the only patient there. He is knowledgeable, attentive and thorough. The lady that took my initial information was fantastic, she made me feel like I was the first patient of the day. I highly recommend DR. Coran and his staff.
