Dental practice of Dr. Zhao is run most efficiently. Entire operation runs like a clock work. Dr. Zhao is caring and a perfectionist. Grace as an overall office manager is simply fantastic. Dr.'s assistant works with Dr. Zhao like a hand and glove. She is caring and anticipatory and always has a smile. Its a pleasure to be a patient of this office. My wife will soon become the patient of this office too. We are simply delighted. Thanks.
