About
Bio
I was born and raised in Hong Kong. After graduating with MD-PhD in Case Western Reserve University in Ohio, I finished my internship and residency in Stanford. I am board certified in Family Medicine. My passion is patient care, realizing medicine is my calling. I have excellent training and years of clinical experience to see patients in all ages. I have been invited public speaker in local radio and public health lectures. I am appointed as Stanford Clinical Lecturer and have seen patients in Kaiser, Stanford Hospital Clinic, and recipients of several certificates and award for extraordinary service and teaching. I am seeing private patients in Saratoga Medical Clinic. My special interest is public education in oral/facial problems, and early diagnosis and behavioral treatments of chronic headaches and obstructive sleep apnea.
