Lead Dental Assistant

Professional and focused, yet light-hearted, Mary is the quintessential dental assistant. She has worked in general dentistry for over twenty years and has specialized in periodontal care with Dr. Lightfoot since 2005. “I have confidence in what Scott can do for his patients,” she said, the all-business side of her personality kicking in.

Involved in all patients’ treatments and scrupulous about their well-being, she is always available to answer questions and offer knowledgeable recommendations. She enjoys helping patients understand their treatment and making sure they are comfortable.

A dedicated reader of non-fiction and a long-time quilter, Mary lightens up watching The Real Housewives of Beverly Hills, indulging in chocolate, and relaxing with her toes in the sand on Mayflower Beach in Dennis. Trips to the Grand Canyon and Sedona are on her bucket list. Her sage advice: “Butter makes everything better.”


Friendly and soft-spoken, Debbie is the voice of the front office. She strives to meet the needs of all patients and make every visit comfortable and stress-free. Although she has been employed in dentists’ offices for over twenty years, she considers Dr. Lightfoot’s practice special. “It’s enjoyable to come to work. Our team has a strong rapport with each other and with the patients.”

The mother of three grown children and the Gigi to two grandchildren, Debbie runs daily and exercises faithfully. She has kept a runner’s journal throughout her adult life, noting that she’s slowed down over the years, but her youthful appearance and abundant energy would defy that description.

Originally from Windham, Connecticut, she now lives in Pembroke. She has the great fortune of being married to a man who likes to cook.

“It’s been a road I’ve been lucky to be on,” she says, her smile genuine, her compassion sincere.


Sarah enjoys helping people and has made that her professional goal. “I like having a personal relationship with people throughout their treatment. I want to make what can be a sensitive time easier for them.” Sarah is a Certified Dental Assistant who attended Rockland High School and the Porter and Chester Institute for Dental Assisting. She enjoys the outdoors and nature in any form. She and her husband love exploring new areas together, especially when it involves walking their dog.


Dental Hygienist Sheila likes the modern, state-of-the-art office of Dr. Lightfoot where she is part of a friendly and fun team. “I like working with people and helping them.” Sheila attended Marshfield High School and Cape Cod Community College. She specializes in perio-maintenance and oral screening. When not cooking and doing laundry for her two teenaged sons, she enjoys kayaking, hiking, and practicing yoga.
