About Us

Family Owned & Operated Since 1985

Opening the doors at Diesel Pro in 1985, Lance Donaldson saw a need for quality diesel service in South Central PA. Diesel Pro began as a small fuel system re-manufacturer in Glen Rock, PA. Over the past 30 years we have experienced expansive growth. We now have three unique Diesel Pro locations to offer a variety of services for our customers. Diesel Pro continues to have a firm belief in honest and loyal relationships with our customers.

With over 30 years in the diesel industry, Diesel Pro has gained a strong following with our superior customer service. Diesel Pro continues to follow our formula for success: Constantly expanding to accommodate current advances in diesel technology. With thousands of parts in stock, test stands, and service bays, we are all you need for the repair and service of your diesel application.
