Matthew has been working with tools his entire life. When he was just 15 years old, he rebuilt his first engine. Since then, he has worked in the diesel mechanic industry, repaired conveyor belt systems, and spent years as a handyman. He has always loved taking things apart and figuring out how they work.
Matthew also spent 3 years working as the only Telebelt mechanic in the Midwest, where he was responsible for fixing anything that broke down. That experience gave him deep hands-on knowledge of heavy equipment and complex machinery.
Matthew is one of those rare people who truly loves tools. If you’re not sure what you need, he can walk you through the entire process — from choosing the right tool to making sure you get the best price.
