Dr Mario holds a special interest in treatments like crowns, bridges, root canal therapy and cosmetic dentistry. Over the course of his professional career he has completed over 600 hours of continuing education, specifically in areas such as oral implantology, pain control/hypnosis, and sedation dentistry.

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. His guidance allows him to promote a shared vision throughout not just our own practice, but the dental industry as a whole. He tells his trainees to “be the dentist the patient needs; don’t try to create the perfect patient for yourself.” Through his coaching, he trains practitioners on how to better communicate 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 amazing,” he says, “I like people…I try to understand what they need, want and where they’re coming from.”
