    I think that this doctor was one of the best doctors and the most positive experience I've ever had. She is kind, she is knowledgeable, she reads up and can tell you everything about you that's been documented. I cannot say enough good, positive, wonderful things about this doctor. For the first time in a very, very long time, I felt that I had had a real examination and that I was in good hands.
