Hi, I'm Dr. Erinn Chang !

Board Eligible Orthodontist

Dr. Erinn Chang was born and raised in the Bay Area, where her own orthodontic journey began at age 11. During treatment, she became fascinated by how something as simple as a metal expander could create such dramatic changes in her smile. After experiencing firsthand the confidence a healthy smile can bring, she was inspired to help others achieve smiles they feel proud to share.

Dr. Erinn earned both her Bachelor of Science in Biology and her Doctor of Dental Surgery degree from University of the Pacific in Stockton and San Francisco. Knowing early on that she wanted to specialize in orthodontics, she continued her education at Roseman University of Health Sciences, where she completed her orthodontic residency. Throughout her academic career, Dr. Erinn demonstrated a strong commitment to leadership and service. She led organizations including Student Community Outreach for Public Education and Orthodontic Study Club, helping organize free dental screenings for underserved communities and educational seminars focused on orthodontic case studies. In recognition of her academic achievements, she graduated Summa Cum Laude.

One of Dr. Erinn’s greatest goals has always been to return home to the South Bay and give back to the community that shaped her. She is passionate about building meaningful relationships with her patients and creating confident, healthy smiles in a warm and welcoming environment. She believes that patient education is an important part of orthodontic care and strives to help each patient understand the purpose and benefits behind every step of their treatment journey.

Outside the office, Dr. Erinn enjoys staying active through running and hiking, exploring new restaurants, and spending time with her fiancé, family, and friends. She also continues to play the piano, a skill she has dedicated more than 10 years to mastering, completing 11 levels of the Music Teachers’ Association of California Certificate of Merit Program. Whether she is singing karaoke with friends or finding new creative outlets, Dr. Erinn brings energy, positivity, and enthusiasm to every aspect of her life.
