He has been practicing dentistry since 1990, relocating to Australia and re-completing dental school at the University of Adelaide in 1999. He is a member of the Australian Dental Association. Dr Mario is constantly updating his skills in all areas of dentistry, most recently being implant dentistry.
As a preventative dentist, Dr Mario is keen to promote therapeutic methods that preserve natural teeth and reduce the risk of unwanted side effects such as tooth loss and gum disease.

As the principal dentist in our practice, Dr Mario devotes a tremendous amount of time mentoring and training new dentists in key areas of patient care, preventative treatments and pain control.

Through his coaching, he trains practitioners on how to be better communicators with their patients, fully meeting their needs and expectations.
From his first moment in University, Dr Mario knew that becoming a dentist was the right career choice. “I had no idea that dentistry was going to be so fascinating,” he says, “I like people, and try to understand what they need, want, and where they are coming from, and provide options to accomplish just that.”
