Our Dental Hygienists

Our hygienists are very knowledgeable. They assist Dr. Sinclair in designing individual treatment plans, and help provide you with information regarding your dental condition. Beyond helping you to maintain good oral health, they also complete oral exams and review your dental/medical history with you. They are proficient in doing oral cancer screenings and intra-oral and extra-oral head and neck exams. Our hygienists continue to raise the bar when it comes to the non-surgical treatment of periodontal disease.

Kathleen has been with us since 2006.  She graduated from Hudson Valley Community College of Dental Hygiene in 1993.  She also has an undergraduate degree in Psychology from Framingham State.  Kathleen has been a great addition to our staff and has helped lessen the office stress in both a lively and professional manner.
