Dr. John Sim was a great help. He went out of his way for me. You should give him a raise!
I am so pleased with the care that I am getting from Dr. Sim and his entire department. I feel that Dr. Sim is always aware of my history and provides thoughtful advice. When I have needed to call in, he has always been helpful. I never feel rushed. Thank you.
