        I feel that Dr. Cassmeyer gives me great care. He really listens to me. He hears me. He treats me as an individual, and he doesn't rush the visit.

        Dr. Cassmeyer is very friendly and explains things so I understand them.. he is very patient and kind. I appreciate that, as I'm one of those people who gets very anxious at Dr. appointments.
