Clinic History

For more than 30 years the Winnipeg dentist clinics at Garden City Shopping Centre and St. Vital Centre were part of Dentrix – a national dental company owned by Dr. Roger Watson. They were some of the first retail dentistry locations (mall-based dental clinics) in the country.

In 1989, Dr. Mark Johnston, a recent graduate of the University of Manitoba’s dentistry program, became an associate at the Garden City location. In 2006 he became a partner, and in the same year he bought both locations from Dr.Watson, renaming them as Dental Image Therapy Centres. Dr. Johnston operated the clinics under the philosophy that if you treat your staff right and treat your customers right, business will take care of itself. He thought it was important to be active in the communities surrounding the clinics – to build a connection and to lend a helping hand whenever possible. 

Those philosophies are carried forward to our staff today through our current partners, Dr. Donald Dziewit, Dr. Linda Simpson and Dr. Patrick McManus.

A Word About Our Fees

We get many compliments on our clinics. They’re outfitted with the latest dental technology to give the best possible care and to make our patients as comfortable as we can.

Occasionally someone will ask if we charge higher fees in order to pay for the advanced technology. The answer is no. We follow the Manitoba Dental Association’s suggested fee schedule. That means our fees are almost identical to most other dental offices in Winnipeg.

We believe strongly in keeping our fees low, and we also believe we should be investing in our clinics to ensure we can offer great patient care. If you ever have a question about our fees, please don’t hesitate to ask.
