About Us 

    Like many other businesses, Dufferin Diesel Works began with one man, a truck, and some tools in 2009. Since then, Dufferin Diesel Works has grown into a full-time truck service and repair facility with several employees in the heart of industrial Orangeville. 

    Having grown up here, we are proud to be serving Dufferin and surrounding areas! We specialize in diesel truck service and repair but offer many beneficial services. 

    Our goal here is to work hard, provide honesty and integrity in our work, and treat your vehicle with as much care as you do. We strive to maintain a clean and positive work atmosphere and provide our customers with experienced and qualified workmanship. 

    We are grateful to our loyal customers who continue to provide positive word-of-mouth. Our suppliers provide us with quality parts and serve us in a way that benefits our customers. We appreciate our dedicated employees who work hard and show both care and pride in their work. In all this, we are thankful to God for giving us supportive family and friends and for guiding us in this venture.

In 1999, he married his wife Hetti and earned his 310T Truck and Coach Technician Certificate of Qualification. Hetti grew up on a dairy farm near Hillsburgh, one of seven children. She has a background in business administration and works behind the scenes. In 2009, after Jeff had gained many years of dealership experience, they started Dufferin Diesel Works as a part-time venture. Since then, the business has grown and now operates full-time as a truck service and repair facility in Orangeville.Jeff has worked countless hours and fixed many trucks. He spends most of his time on the phone with customers and suppliers these days, but will still turn wrenches if the job has to go! Hetti continues to be active part-time in the administration of the business.
