Dental Hygienists

We have four licensed hygienists serving our patients. Our hygienists are a valuable component of our commitment to quality dentistry. A hygienist is a trained and licensed professional who has completed a college degree in dental hygiene, obtaining either an associates or bachelors degree. Dental Hygienists are specialists in the prevention and early treatment of periodontal disease and are invaluable in assisting patients achieve and maintain optimal oral health. Education and prevention is a critical focus of our office and our hygienists are specifically trained to educate and assist you, our patient, to achieve and maintain your oral health.
We encourage you, when possible, to see the same hygienist each time you come. This approach not only allows you to have a personal relationship with your preventive care provider, but also allows for more complete evaluation of your improvements over time.

Dental Assistants

Our dental assistants are invaluable in the delivery of good dental care and they are the first line of defense against tooth and gum disease. We have a great staff of five trained dental assistants who work with all of our dentists. They help to prepare our patients for dental procedures and can answer questions about oral health.
They assist the doctor chairside in all dental procedures from crowns to extractions. They are responsible for taking radiographs, impressions, making temporary crowns, arranging laboratory cases, the maintenance of supplies and equipment, and keeping strict adherence to OSHA sterilization/disinfection protocols.
