Our Hygienists

Studies show that over half of the U.S. population has some form of periodontal disease. Prevention is the top priority for our hygiene team. Our registered dental hygienists are highly trained professionals who have earned college degrees and passed licensing exams. Everyone in this office believes in good oral health and our hygienists are a very important part of our patient care. If you have any questions about how to care for your teeth, please ask your hygienist for suggestions.
