Founder & orthodontist
Dr. Sally Chaekyung Lee
Science-led care, refined with an eye for natural balance.
Dr. Lee graduated summa cum laude from Yonsei University College of Dentistry, receiving the top award in her class. She completed her orthodontic residency at Severance Hospital and a PhD in orthodontics at Yonsei, and trained abroad through an exchange residency in orthodontics at the University of Southern California and an exchange program at UCLA.
She is a member of the Edward H. Angle Society of Orthodontists (Northern California Component), where membership is earned by presenting one's own treated cases to fellow orthodontists. She also serves as a peer reviewer for the American Journal of Orthodontics and Dentofacial Orthopedics (AJO-DO), the official journal of the American Association of Orthodontists and one of the leading journals in orthodontics.
Her approach combines precise diagnosis with careful attention to the bite, facial harmony and long-term stability. She explains the reasoning behind each decision in plain English, so patients understand their treatment at every stage.
