I then went on to Boston University from 1981-85 and graduated Cum Laude with a Bachelors of Science in Anatomy of Physiology. I worked for 2 years as an Emergency Medical Technician in Melrose, MA, and then continued my education at the university of Pennsylvania School of Dental Medicine and graduated 2 ^nd in my class in 1990. I then worked in both Lynn and Brockton as a general dentist for 3 years, then in Billerica for 2 more years until I purchased this general practice in Haverhill in 1997. I have continued my education with the introduction of CEREC, (One Visit Crowns).
