my new dental clinic in Gatineau
is here for your smile
After practicing for nearly 20 years at a dental clinic I loved, a little voice reminded me of my lifelong dream: to create a clinic that reflects my vision, where patient care, people, and the environment are at the heart of everything.
As they say, it's never too late to make your dreams come true—so I went for it!
Mon Dentiste Lajoie (yes, the name says it all, this clinic is yours as much as it is mine) is a welcoming, unpretentious space where respect for patients and my co-workers is the top priority—a place where you'll feel comfortable, a bit like a home away from home. Here, every smile matters, every action is purposeful, and every detail has been carefully considered for your well-being, that of our team, and of our planet.
Our clinic was designed with ecological values in mind: sustainable material choices, responsible resource management, and a conscious approach to our daily impact. Because a beautiful smile shines even brighter when it's part of a sustainable approach.
I have a very approachable personality and, I've been told, a great sense of humour. I love to travel, cook, and spend time with family. These passions inspire me every day to create an environment where light heartedness, kindness, and a sense of community prevail.
It is with great enthusiasm that I welcome you to Mon Dentiste Lajoie — a place where taking care of your smile is truly a pleasure.
