Dr. Lee was amazing! My dental cleaning was completely painless, and she was incredibly kind and caring throughout the entire visit. She took the time to explain everything thoroughly and made sure I understood each step. I truly appreciated how attentive and detail-oriented she was. She’s an excellent dentist, and I highly recommend her!
