Dr. Derrick Chua

Membership chair

As a member of the American Dental Association, California Dental Association, and San Mateo Dental Society, I join other dentists to secure quality care for generations. Participation in these groups, allow me to fulfill my commitment to continuing education and improve my clinical skills aiding my constant evolvement as a dentist. I regularly attend meetings of the Bay Area Aesthetic Masters and annual meetings of the American Academy of Cosmetic Dentistry to improve my skills and be able to offer my patients the best practices for improving their smile. My goal of excelling as a dentist has required me to train with leading experts in dentist-patient relationships, cosmetic dentistry, implants and advanced endodontics. Working with my mother and sister in our family practice has been also proven very fulfilling. I spend countless hours perfecting the art of dentistry and I strive to learn on a daily basis and be the best I can be in my personal life and for my patients.

My wife and child bring further balance to my life. Both my wife and I are avid tennis players. I also enjoy snow skiing and golf. The paramount purpose in my life is being a “great dad.”
