Barbara Tosti, RDH, Office Manager


Barbara graduated from the University of Vermont with a B.S. in Dental Hygiene.  She began her career in Vermont working in a periodontal office.  She was fortunate to combine her desire for travel and her career with an opportunity to move to Switzerland where she worked in a dental office for three years. There she really honed her skills and developed a passion for sharing successful strategies with patients.

Missing her friends and family, she returned stateside to work. Upon her return, she was given the opportunity to work in dental management of a team. The transition from clinical to management was not planned, but she found it to be a welcome change.

Her dental management experience makes her invaluable to our team and she is extremely helpful; you can count on her for knowledgeable answers to your questions about appointments, Insurance, financial arrangements, and benefits coordination.

She still maintains her Dental Hygiene license, so you may still see her on the clinical side! In her free time, she enjoys her large family of many brothers, sisters, aunts, uncles, cousins, nieces and nephews. She loves, cooking (and eating!) biking, and gardening. She lives in Framingham, where she is originally from, and loves to travel whenever she can.
