Dr. Hsu performed a root canal on one of my molars that was infected. I would recommend him to any person needing this procedure. His office is immaculate. He uses state of the art technology, including digital X-rays that allow you to see the images on a flat screen TV attached to the chair. He is extremely kind, caring and very thorough. I felt no pain after the novacaine took effect. The office staff is extremely thorough and caring. Every time I called with a question they knew me and showed true concern for healing. I would recommend Dr. Hsu to any person that needs this procedure. If I ever need another one, I will definitely be returning to Dr. Hsu.
