About Us

The foundation of Chancellor Dental Group began with Dr. Jim Bonar associating with Dr William Harwood in 1986.
Dr. Bonar purchased the practice in 1987 and brought Dr Alex Pappas in as a partner in 1991. Ultimately they formed Chancellor Dental in 1995 with the construction
of their new office at 343-18th Street, across from Brandon University.

The new office was developed with space to allow for future growth. An increase in business led to staff increases including two additional dentists; Dr. Darci Bonar in 2011 and Dr. Joe Thiessen in 2012.

These changes necessitated a complete renovation in 2012 and significant technical upgrades including digital x-rays, fully paperless charting, CT scanner and state of the art sterilization area.

Chancellor Dental is very pleased with the investment in cutting edge equipment but what has remained the same for over 25 years is their primary focus- their patients.

Chancellor Dental provides patient-centered care for patients of all ages, and includes a broad range of services including cosmetics, implants, surgery and orthodontics in addition to general family dentistry.
