Proudly Serving Your Uxbridge Family

Our highly-experienced team is committed to providing you with a relaxing and comfortable experience each time you visit. Here are some of the friendly staff members you’ll meet when you arrive.


Dentist Uxbridge, Dr. Andrew Gregorio

Dr. Andrew Gregorio, Associate Dentist

Dr. Andrew Gregorio is a 1989 graduate of the University of Toronto. He has extensive professional development training in multiple aspects of dentistry, including orthodontics (braces) and endodontics (root canals).

When he’s not busy working as an associate dentist with Dr. Dave, Dr. Andrew enjoys shuttling his son between karate lessons and soccer practice. In fact, Dr. Andrew is an avid soccer player himself, having played since age 10. He is currently a member of a city men’s league.

Outside of studying new dental techniques, Dr. Andrew enjoys learning about other languages and linguistic patterns, primarily French and Spanish (he took courses in both at the University level). He also understands some Hungarian, as his wife Eni (Eniko) is Hungarian. Eni is fluent in Romanian and works with Dr. Gregorio as his dental assistant.
