I've been seeing Dr. Ruff for my skin cancer issues for over two years and I give him a Five Star rating for friendliness and for his expertise in solving my issues with knowledge and consideration of my desires and feelings. I wouldn't hesitate to bring any dermatological problem to him knowing I would receive the best care available.
