Serving the area since 1977, our doctors and staff care about you and your dental needs. Highly skilled and trained in several areas, including general dentistry, orthodontics, periodontics and cosmetic dentistry, most of our staff members have been with the practice for over 20 years.

General Dentistry

Dr. Trieu Nguyen and Dr. Megha Shah offer many general procedures, including routine cleanings to thoroughly exam your mouth, fillings, crowns to replace and restore your tooth structure and root canals to extract the decayed tooth pulp.


Our in-house, board-certified orthodontist, Dr. William Harrison, provides orthodontic treatment that not only results in an attractive smile, but also correctly aligns teeth to provide ideal jaw function. He offers his patients Invisalign, clear brackets or mini brackets.


Dr. Kevin Lee is board certified, specially educated and trained in the area of periodontics. He provides periodontal evaluations to detect and treat gum disease.  If a patient loses a tooth to periodontal disease, Dr. Lee can place a dental implant as a permanent, natural-looking solution.

Cosmetic Dentistry Procedures

From chipped or missing teeth to discoloration, our experienced team works together to provide you with veneers, teeth whitening, bridges, bonding and implants in order for you to have a great smile.
