We welcome you to our website, and we’d love to welcome you to our family of patients! Dr. Phil Ra and our entire team at Sierra Dental Group understand that most people are busy, many feel anxious about dental appointments, and budgets are most often limited. That is why we strive to make our practice as convenient, comforting, and affordable as possible for the Inland Empire community (without sacrificing clinical excellence). Plus we offer financing options because we understand that monthly payments can help patients fit the costs of dental treatment into their budgets. We want to make it possible for you and your family to enjoy the dental care that you need and desire.

We know that the way your smile looks can greatly affect your personal and professional life, and the first impressions you make on others. We believe that everyone – adults and children alike – deserves a smile to maximize personal health and appearance. By focusing on oral health and early preventive dental care, we are better able to diagnose and treat problems before they grow to be big, often painful and expensive. We also offer a wide range of restorative dentistry and smile makeover options, because we want the residents of Fontana and the surrounding areas to achieve the smiles of their dreams at our office!

Dr. Phil J. Ra was raised in Southern California, and he’s happy to be living in the Inland Empire as he practices the art and science of dentistry. His childhood goal of becoming a dentist became a reality when he was accepted into the Accelerated Dental Acceptance Program Tract (ADAPT) at the University of Southern California right out of high school (in 1994).
