I graduated from Bristol Community College in 2009 with my Dental Hygiene license and I have been working in the dental field since 2004. Educating my patients on their dental needs is very important but I also like talking to my patients to get to known them personally. I started working for Massasoit Dental in August 2013. When I'm not at work, I am a busy mom of two boys. I am an outdoor person: I love the beach, bike rides and going for long distance walks.
