How likely are you to recommend Dr. Smiley?

(Select your rating)
He's a very good doctor, he's very friendly and cares about his patients. Takes time to talk to you about your health and listen to his patients concerns. He honest and sincere about your health just as much as himself. I would certainly recommend him for a kidney doctor.
