Dr Su repeated my entire implant procedure including the bone grafting at no cost to me or my ínsurance company when my body didn't grow enough bone to support the original implant.I have never experienced a more competent and professional specialist before Dr Su.

“My daughter had surgery with Dr.Su, at first I was skeptical and worried about how the surgery would go, but it went very well and Dr.Su did a fantastic job. She is an excellent dentist. I was very lucky that I discovered her, and I would highly recommend her. Also the staff were very helpful and friendly.”

“Recently got a surgery completed at Periodontal Associates. Dr Su is exceptional and extremely caring. Not only did she perform my surgery with great precision and skill, but she also demonstrated a level of compassion and attentiveness that truly set her apart. Dr. Su made sure I felt cared for. She took the time to answer my questions (I had a lot!) and concerns so that I completely understood what my options were.
