Enza, RDH

Enza brings an international flavor to the Dr. Mark Groskin dental practice. Her parents immigrated to North America from Italy, and it was in Toronto, Canada, that Enza was born and lived for the first five years of her life.

The family next moved to the borough of Queens in New York City and remained there for four years, before finally coming upstate to make their home in Rochester, New York.

Enza attended Greece-Olympia High School, which is where her interest in medicine and medical care began. She decided to go into either hygiene or nursing, and eventually entered the Hygiene program at Monroe Community.

She’s spent fifteen years now providing hygienic care to people and patients – the last nine of those years, at Dr. Mark Groskin Dental Practice. Enza feels there’s more to good care than only cleaning teeth.

“We need to educate people,” she feels.

“Groskin runs a good office and hires good people. The people working there seem conscientious and focused on the patient. I definitely recommend him and his staff, they really seem to do things right and do the best for their patients. There is a down-to-earthness about his practice.”
