Dr Hagaman is a really good doctor. That's why I waited to get to an appointment with him instead of anywhere else. He always listens, cares, and explains things really well.

The doctor was clear about the treatments he was recommending, why he was recommending them and the benefit of trying these treatments/medications in combination with each other.
