San Marino Dentistry has a 40-plus year history of caring for the residents of San Marino. In October 2018, Dr. Jonathan Song bought the practice from retiring dentists, Dr. Cynthia Diep and Dr. Tin-Hoag Nguyen, and can’t wait to continue the legacy of the doctors who have served the community in the same location.


Dr. Jonathan Song

Dr. Jonathan Song earned his Doctor of Dental Surgery degree from the University of Minnesota, School of Dentistry and was selected for a one-year rigorous General Practice Residency at the Rancho Los Amigos National Rehabilitation Center (RLANRC) in Downey, CA. While there, he was able to help many patients with special needs and was voted “best resident of the year.”

Dr. Song is committed to continuing education and takes many advanced courses each year to enhance his skills to best serve the dental care needs of his patients. He is a member of the American Dental Association, the Korean American Dental Association, the American Academy of Cosmetic Dentistry, the California Dental Association, the Academy of General Dentistry, the International Association of Dental Research, the American Academy of Sleep Medicine, the San Gabriel Valley Dental Society, the Contemporary Dental Institute, and the Pacific Implant Academy.

He believes the most important aspect of dentistry is the positive relationship between a care provider team and their patients. He donates his time once a week to local hospitals to provide quality dental care to the community and aspires to be the most caring dentist in Southern California. He is eager to spread his belief one smile at a time.
