Patient Reviews
Sep 10, 2019
He is the most attentive doctor I have ever visited. He not only listens intently to what you are saying but he is not an alarmist that then says "well this could be serious, maybe we need to run some tests." He is also a doctor that does not push medications like most doctors do. I am a firm believer that if I can make lifestyle changes instead of medications I would prefer to do that course of action. He is always willing to tell me what changes to make and gives me time to see if these changes can help my condition. I HIGHLY HIGHLY recommend this doctor and wish more doctors were like him.
