Meet the Team

Dr. Judyth Lee and Dr. Esther Yun first met as dental school classmates at Tufts University School of Dental Medicine and quickly became friends. After graduating, they went their separate ways until Dr. Esther relocated to the Bay Area and reconnected with Dr. Lee. Their aligned philosophies and complementary strengths made it clear that opening a practice together was a natural fit. That connection led to the creation of Big Little Teeth Pediatric Dentistry, where they now provide thoughtful, modern care to families in Foster City and the surrounding communities.
