Full Biography



Marie Perella-Sullivan


Marie Perella-Sullivan, Dr. Fiore’s office manager, has been with the family owned practice since 1972. She started working part time after school as a clerical assistant and was hired as a full time dental assistant after graduating from the University of Massachusetts with a degree in Biology.

Dr. James Fiore mentored all of his employees, and Marie credits her wide spectrum of dental skills such as laboratory technician, dental assisting and front desk management to his patience and tutorial expertise. She recalls being hesitant about conversing with patients when she first started working in the dental field. She thanks both Dr. John Fiore and his father with encouraging her to expand her knowledge and the scope of her duties.

The office is very much like a family. The care and consideration that is extended to every patient stems from the respect and thoughtfulness that the staff have for each other. And truly an appointment at Dr. Fiore’s office is like a visit with old friends!
