From the moment you walk into our Elk Grove dental office, you will feel welcomed and treated like family. After 24 years in practice together, Dr. Peter Ngai and Dr. Penny Phipps continue the commitment to give you the highest quality dental care you and your family need and deserve.  We have assembled a team of fantastic professionals who love caring for their patients and truly enjoy the work they do. Our commitment to ongoing education allows us to learn about the newest dental techniques and technologies and then offer those services we believe to be the most beneficial to our patients.  Dr. Ngai and Dr. Phipps believe in providing minimally invasive dental care whenever possible. One of our goals is to give you the tools you need to take an active role in your own dental health. We are happy to discuss any dental concerns you have and teach you home care techniques to keep your mouth healthy and your teeth and gums strong.  Call us today to find out more about our office and what it means to be treated like family.

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.

Dr. Penny Phipps

Dr. Penny L. Phipps

Dr. 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 time while her youngest son is in school. In addition to spending time with her children, she enjoys hiking and skiing.  Dr. Phipps does especially well with phobic patients, taking the time to accommodate their needs.  She also does most of the oral surgery and the root canals for the practice.
