Meet Our Team

Dental hygienists and dental assistants are a vital part of a good dental team, and work closely with the dentist to provide optimum dental care. They provide treatments such as root planing, scaling and prophylaxis for periodontal diseases. They also teach patients how to care for their teeth, as well as contribute to comprehensive dental diagnoses by providing diagnoses on your dental hygiene.

Our friendly and courteous office staff are always happy to assist old and new patients throughout their dentist visits. They will help arrange and manage your appointments and follow-up visits, and answer any questions and concerns that you may have.
