What I could say about Dr. Brennan is he's right on the ball when he talks to you and awesome guy down to earth explains things very easy on layman terms I should say and I'd highly recommend him. I went to other hospitals in the past and I felt like a number there. I'm very pleased with him and Exeter Hospital.
