Dr. NuiNopsaran Chaimattayompol, DMD, MPH

“Missing teeth consider an oral amputee and decrease quality of life. It’s tragic when people suffer just because they’re afraid to see a dentist. That’s why I’ve dedicated my practice to rehabilitate oral function and esthetics and making dentistry gentle and comfortable.Rest assured that I will provide you with the highest level of oral care. Your satisfaction means everything to me.”



Dr. Wong – Stefanie Wong, DDS

“The bottom line is that I want you to be satisfied with my work. And that’s why I practice ‘people-oriented dentistry.’During each exam I spend a considerable amount of time just listening to the concerns of my patients, and helping them to understand why I’ve recommended a procedure, and what it will do for them.”



Dr. Robert Doherty, D.D.S., F.I.C.D

“Through out the years, in which I’ve practice and taught dentistry, I have seen much advancement in the field but the fundamental thing which remains is the ethics of dentistry.I believe every dentist should treat their patient with the utmost respect and care so every tooth in a person's head is more valuable than a diamond.”
