Patient Comments (4)

Makes you wait forever in the room before he sees you. When you ask a question, he brushes you off like you're stupid and he can't be bothered. Acts like you're wasting his time, and you know nothing about your illness because clearly, you are not the Dr.

I have type 2 diabetes. I have been going to Dr Chapin since his office opened. He has listened to what I tell him and we discuss the problem and he tells me what he thinks will help me. I trust what Dr Chapin tell me I need to do. If he thinks what I suggest to him is something that will help me...more
