Dr. John is the best doctor I have ever had. I've been seeing him for years and he is the first and only doctor I feel really listens to me. He does not rush you through appointments and really cares about his patients. Dr. John is also very humble. If he doesn't know enough about something you ask, he will say that and get you referred to the correct person/clinic. He doesn't want to risk giving you misinformation, and saying that shows he actually cares about you more than his ego. He wants to make sure you have the best information as possible regarding your health.
