Doctor knows what he is talking about. It took him about 30 seconds of test, 30 seconds of listening to diagnose me with severe GRD and then a prognosis with info I needed about what to do, diet, and med he was to prescribe. He gave out a coupon for the med, advised if it wasn't covered by insurance to call and he'd get something else going. He listened to me when I advised of a family history item and then scheduled a GRD to check things out, which turned out a non-issue in my case for now. He also gave me a six-month future plan when I went for what he wanted to do. Was quite nice. Was impressed with how quickly he diagnoses and came to a decision. He definitely knows what he is talking about and has quiet a few years of experience.
