5/5
Dr. Tiffany Chien is an incredibly meticulous and thorough endodontist. She takes the time to explain every detail of the treatment process beforehand. Despite being young, she has a very steady hand and demonstrates great professional expertise. Her approach to anesthesia is extremely careful—I didn't feel any discomfort during the procedure. I highly recommend Dr.Tiffany for root canal treatment
