Dr. Ashley Chan is proud to serve the community she grew up in. A San Mateo native, she attended North Hillsborough Elementary School, Crocker Middle School, and Aragon High School before earning her B.S. in Biomedical Engineering from UC Irvine. Her journey into dentistry began as Dr. Dely Young and Dr. Chrystle Cu’s dental assistant—an experience that inspired her to pursue her Doctor of Dental Surgery degree at the University of the Pacific, Arthur A. Dugoni School of Dentistry.
Passionate about enhancing quality of life through better oral health, Dr. Chan is dedicated to educating her patients and empowering them to achieve confident, healthy smiles.
Outside the office, Dr. Chan loves exploring new cultures and cuisines. Some of her favorite trips have taken her to Myanmar, Morocco, and Italy—but her favorite place in the world is Maui. She doesn’t have pets or kids yet, but she is a certified plant-mom.

That same year, she founded Young Dental Group—a practice built on compassion, education, and a love for creating beautiful, functional smiles. Her early passion for orthodontics and dentofacial orthopedics shaped the comprehensive care philosophy that still guides our team today.
Dr. Young continues to share her wisdom and mentorship with Young Dental Group. When she’s not inspiring future generations of dentists, she cherishes time with her grandchildren.
