Very personable from start to finish. Everyone is professional and friendly. Excellent job of explaining what they are doing, why they are doing it. and results. Demonstrated exercises for hand. Made it very clear about what to expect. Best U.C in area.

Dr. Greger is very professional and descriptive with helping me understand my pain. He addressed the underlying cause instead of just prescribing meds.
