Meet Our Doctors

Dr. Stephen-Gangbar

Meet Dr. Gangbar

Dr. Stephen Gangbar graduated from the University of Toronto, Faculty of Dentistry. Upon graduation, he did a general practice residency at Health Sciences Centre Hospital, the University of British Columbia. Returning to Toronto in 1986, Dr. Gangbar practiced general dentistry for one year before returning to the University of Toronto for graduate studies.

In 1989, Dr. Gangbar received his specialty certification in Periodontics and began practicing with Periodontal Associates. He is also on staff at the Faculty of Dentistry, University Of Toronto as a Clinical Instructor in Periodontics.

He is a director of the PA Study Club and has lectured to many dental groups. Dr. Gangbar is also a member of the Ontario Dental Association, the Ontario Society of Periodontists, the Academy of Osseointegration, the American Academy of Periodontology and many other national and international dental societies.

When I started practicing in Oakville, I sought out specialists for perio and implants that I could form a long relationship with. I decided Periodontal Associates and Dr. Stephen Gangbar was who I wanted to work with. The excellent treatment outcomes, the ability to communicate and work together on treatment plans, and helping me learn through their study club, has all been instrumental in my success with patients. Periodontal Associates is not close to my practice, but they are my only real choice when my patients want implants, cosmetic perio or just routine perio treatment. And I send my family to them as well!
