Best dentist in Tri-Valley! My family has been coming here for 25 years. All 5 of us love Dr. Wong and his team. Katie, Marie, Nancy, Sholpa and Maggie are all wonderful and caring. You can trust them to do an excellent job, whether it is for cleanings, cavities, crowns, braces, implants or teeth whitening. We have had it all done here by Dr. Douglas Wong.
