Dr. Merrill is a vanishing breed. He was prepared for the appointment and actually had reviewed my patient records. He spent more time looking at me than the computer, and he offered some solutions that I can work on now before further testing. He was personable and treated with an ease that is rare. Keep this doctor in patient care and away from administration!!
