Meet the Family & Preventive Dentistry's Staff



Trisha is a lifelong resident of Connecticut. She has worked for our dental practice since 2001. Over the years, she has participated in Connecticut's Dental Mission of Mercy, a dental volunteer program treating those less fortunate.



Trish attended the Forsyth School for Dental Hygienists and Northeastern University in Boston, MA. She received her bachelor's degree from Northeastern and began working as a dental hygienist for the Harvard School of Dental Medicine.

She returned to Connecticut and worked for Dr. A. Howard McLaughlin, beginning in 1985 until the practice was assumed by Dr. Marshall, and then joined by Dr. LaRosa. Trish has worked continuously as a hygienist since 1981.

She currently lives in Prospect with her husband and they have two adult children.



Mary graduated from Post Jr College as a medical secretary and received her Associate in Science degree from Teikyo Post University. She accepted a position with a Waterbury surgeon and as the practice flourished and staff expanded, she was instrumental in establishing the first industrial clinic in Waterbury. Mary worked as an office manager for 32 years until the doctor's retired in 1998.

In August of 1998, Mary accepted a position with Dr. Marshall as an appointment secretary and financial coordinator, and in 2002, Dr. LaRosa joined practices with Dr. Marshall and today we are known as Family and Preventive Dentistry P.C.

Mary enjoys cooking and gardening at her home in Litchfield.



Andrea graduated from Suesc University in Brazil with a degree in Business Administration. Here in this country, she was a Manager at Dunkin Donuts for over ten years before joining our practice as Dr. Marshall's dental assistant, caring for patients' chairside. She has been with the practice since 2008 and is fluent in Portuguese and also helps our office communicate with a variety of patients.

While she is not working, she and her husband are busy raising their two children, Rebecca and Alex.



Janette has enjoyed a career in Dentistry most of her life. She previously earned her certification as a Dental Assistant and went on to further training in dental lab work. She then became an Office Manager in a specialist office in New York City before moving to Connecticut. Once in Ct, she attended and graduated from Tunxis Community College in 1993, which is affiliated with UConn Health Center, where she did most of her clinical work. In 1994, she began working with Dr. LaRosa.

Since merging practices in 2002, she has contributed towards creating a practice that offers our patients preventive, professional, and comprehensive care. Janette feels extremely fortunate to be able to look forward to going to work and also to continue to pursue her studies in health and nutrition.

Janette lives in Woodbury with her husband Steve, and has two wonderful sons and daughters-in-law, with two amazing granddaughters.
