Meet Our Team

Dr. Peter Ngai, DMD

Dr. Peter NgaiDMD

Dr. Peter Ngai received his DMD from the University of Pennsylvania in 1991, graduating valedictorian of his class with numerous awards. He then completed two residencies in general dentistry, one at the University of Pennsylvania and one at the University of California, San Francisco. Although Dr. Ngai originally planned to continue in periodontics, he realized he would miss the variety that general dentistry has to offer.

Outside of dentistry, Dr. Ngai loves cars – specifically high performance cars. When he has the opportunity, he likes to teach high performance driving schools at the race tracks. He also enjoys photography- some of which you will get to see when you come to our office.

Dr. Penny Phipps, DDS

Dr. Penny Phipps received her DDS from the University of California, San Francisco, in 1994 with an award for her work in pediatric dentistry. She then completed a residency in general dentistry, also at the University of California, San Francisco.

Because her family is such a high priority, Dr. Phipps limits her practice to the time when her children are in school. In addition to spending time with her children, she enjoys hiking and skiing.
