Dr. Matsunaga should be used as a role model for other doctors regarding communication and interaction. He is attentive to the inputs I provide regarding my care and provides clear and concise explanations when necessary. His personality promotes a relaxed and trusting doctor/patient relationship and he's a darned good urologist also!
