“This is my 2nd time seeing Dr. Yip, and I would definitely recommend him and his staff to anyone. They are personable, helpful and sensitive. I live in Riverside, and I originally went to Dr. Yip because he had the 1st available appointment of all the doctors that I reviewed; I still go to him because he is worth the drive, and is an excellent doctor.”
