Outside of dentistry, I cherish spending time and traveling the world with my wife. I enjoy staying active by working out and playing golf. As an avid sports fan growing up in the Bay Area, I love rooting for the Golden State Warriors, 49ers, and SF Giants.

What Our Patients Say About Us
Truly this was the best experience! Dr. Chieng and his assistant explained each step of what they were performing. Also, their professionalism was what really stood out. Going to the dentist can be frightening and sometimes embarrassing, yet they addressed my dental issues with dignity and a clear plan that would put me on the road to proper dental care. This was my first time, I walked out of the office with a full exam AND a deep cleaning! I felt minimal pain. I’m impressed and glad that I switched my family over to this office. 😃
I had a great experience at this Dental office. Everyone is so nice and welcoming, I went in for some fillings with Dr. Lee and had my cleaning done with Clarissa. Both are awesome, very gentle and knowledgeable. Definitely referring my family members.
I had a great experience at The Dental Office of Rancho Cucamonga. The staff was friendly, the office was clean, and the dentist took the time to explain everything clearly. I highly recommend them if you're looking for quality dental care.
