Dr Treanor is a very fine Doctor whom has been so kind and engages in conversation of questions ask and take time to explain to me what I need to know. I moved out of state and still want to keep him as my Doctor.

Dr Treanor took time to visit with me before and after the procedure, explaining what he was going to do and then what he had found. He, along with his staff were courteous and caring.
