      I was referred to UCSF dermatology by my doctor and I'm glad this happened since I consider the care provided by UCSF as exceptional comparatively. Dr Yu and her staff were very kind, communicative and showed true professionalism during my visit. Everything about my treatment was clearly explained by residents in training and Dr Yu.
