Our history

Mr. Diesel Inc., founded by Bill Sevigny in 2007, draws on over 30 years of experience in the trucking and diesel engine industry. Bill’s career began in 1992 with prominent truck manufacturers like Mack, Freightliner, and Detroit Diesel, where he honed his skills in transmission and differential troubleshooting. His expertise was further expanded during his tenure at Waterous (now Wajax), focusing on engines and power units. With just a service truck and a solid mechanical background, Bill launched Mr. Diesel Inc. in 2007. Since then, the company has built a reputation for excellence, servicing trucks, mobile cranes, and oilfield equipment.
