Dr. Peter Ngai

Dr. Peter Ngai

Dr. Ngai received his DMD from the University of Pennsylvania in 1991, graduating valedictorian of his class with numerous awards. He then completed two years of Advanced Education in General Dentistry residencies, 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. When Dr. Ngai is not busy with his practice and kids, he enjoys teaching high performance driving at race tracks around Northern California. He also enjoys photography- some of which you will get to see when you come to our office.

Ultimately, she hopes that with a sense of balance between her personal and work life that she can maintain that joy through work for many years to come.
