MY HANDS BUILT, MY EYES INSPECTED, AND MY EXPERIENCE SECURED STRONG FOUNDATIONS.
Here’s my Story Personal Journey:- My journey in construction officially began in 1995, but my love for building started long before that. As a kid, summers in my hometown of Lac-Megantic, Quebec, were spent hammering away at treehouses with my best friend, using old barn wood we salvaged ourselves. That’s where I first discovered the joy of creating something with my own hands.
In high school, I realized that building wasn’t just about wood and nails—it was about people. I wanted to help others by creating safe, strong homes, which led me to pursue a career in construction. From pumping gas in my early days to becoming a certified home inspector and mold consultant, every step of my journey has shaped the professional I am today.
Now, with decades of experience, I’m more committed than ever to delivering quality, integrity, and expertise to every project.
REFLECTION, INSIGHT, AND CONTINUING GROWTH
Reflecting on my journey, I’ve come to appreciate the profound impact that mentorship has had on my growth as a construction professional. From my father, who first introduced me to the joys of building, to the seasoned contractors who generously shared their knowledge and expertise, I’ve been fortunate to learn from some of the best in the business. With expertise across two provinces and two countries, I have become a trusted source of knowledge in the industry. I bring an innovative approach to waterproofing and project management, combined with a focus on intensive customer service.
In high school, a teacher once asked me, “What do you want to do with your life?” My answer was simple: help people! I do this by using my knowledge and skills to benefit others. My expertise stems from years of learning from others and putting in hard work.
