Our dental clinic has played an important role in Sainte-Catherine for over 40 years now. First managed by Dr. Pierre Brisson for nearly three decades, the clinic built an excellent reputation in the community and many patients remained loyal over the years. The clinic was then purchased and renamed after its successor, Dr. J. Y. Lareau, who managed it for nearly 10 years.

The next generations of patients followed in the footsteps of their family members, placing their trust in the clinic and contributing to its success. More than a simple dental clinic, it’s family, one that truly cares about your well-being.

This year opens a new chapter in the history of the clinic. It has been purchased by Dr. Petronela Petrosel, a dentist with an impeccable reputation, and has been renamed the Clinique Dentaire Ste-Catherine.

Welcome to the Clinique Dentaire Ste-Catherine, your family dental clinic for over 40 years!
