About Us

Lajoie Bros. was founded by brothers Charles “Chuck” and Aimee Lajoie in 1967. In the 1970s, Chuck’s sons—Mark, Ken, Jim and Jeff—began working alongside them, bringing another generation into the business. Mark, Ken and Jim later took over ownership and continued the day-to-day operations. That history remains an important part of our identity today.
