Registered Restorative Dental Hygienist


Nancy began her career in 1991 when she graduated as a dental assistant from Cambrian College. She then returned to Cambrian three years later to proceed with the dental hygiene program in 1995. Into her 10 years now as a dental hygienist, she maintained her passion to provide dental hygiene care by returning to school at Algonquin college to obtain her Restorative Dental Hygienist certification in 2005.


She has a nice personality with her clients, she is caring, calm and has soft touch.

In her spare time, you will find Nancy taking Latin or social dancing with her boyfriend a couple of times per week. When she's not dancing, she is either on the water or traveling with her boyfriend and her two wonderful kids to the warm climate down south.
