Dr Kao and his staff surpass any possible rating system. Dr Kao was extremely caring and attentive to all my concerns. He was very detailed in explaining his diagnosis. He provides notes for you to take explaining his plans of action. My visit was a first class experience and superior to any other provider. His staff is very punctual, caring, and efficient. Hands down Dr Kao is the best and has my highest recommendation.
