Dr.Phil J. Ra Picture


Dr. Phil J. Ra was raised in Southern California and currently takes pride in residing and practicing the art and science of dentistry in Upland and the surrounding areas. His childhood goal of becoming a dentist became a reality when he was accepted into the prestigious six-year Accelerated Dental Acceptance Program Tract (ADAPT) at the University of Southern California School of Dentistry right out of high school in 1994. Dr. Ra is proud of this accomplishment, as only a select group of students in the nation are accepted into this academically rigorous and clinically grueling accelerated program.
After becoming one of the youngest doctors to graduate with a Doctor of Dental Surgery degree in the history of USC in 2000, Dr. Ra spent several years (and still spends many hours) attaining up-to-date continuing dental education and training to better serve the Inland Empire for over 15 years. His unwavering commitment to staying on top of dentistry’s latest techniques and research has earned him the highly prestigious Fellowship from the Academy of General Dentistry. This means he has the skills gained from more post-doctorate education in 3 years than the State of California requires dentists to take in 20 years of practice.

I got to the dental office a couple minutes after my appt and didn't have to wait. Gil was personable, knowledgeable and kind. Because I had periodontal disease he recommended a deep cleaning. Explained everything as well as after care.
