Meet the Doctor

Joyce Y. Chang, DMD, MS practices in her solo orthodontic practice in Windsor, California. She attended Stanford University and majored in Biological Sciences.

She then graduated from Harvard School of Dental Medicine with a DMD degree. Unlike most other orthodontists, she worked as a general dentist with the US Public Health Service on the Hualapai, Hopi, and Navajo reservations for four years. As a result of her experience, she understands all aspects of dentistry and has expertise in coordinating complex cases with other dental professionals.

After her stint with the USPHS as a general dentist, she attended the esteemed University of Michigan where she earned her Certificate in Orthodontics.

In her spare time, Dr. Chang enjoys endurance cycling, yoga, traveling, and knitting.

“We’re different from high-volume clinics. We prioritize personalized care, individual attention, and quality orthodontic experience.”

– Dr. Chang
