Scott Doney established Diesel Doctor, Inc. nearly two decades ago in 1999, growing the business from a one-man shop to a fully equipped big truck repair facility with about a dozen employees. In the beginning, Scott rented space from other vehicle repair shops in Havre, and worked very hard until he saved enough money and built a clientele to support building his own shop, which he did in 2005. Over the years, Scott has maintained the high standards he set for himself when he started in the diesel repair business, and expects only the best from his staff.

Today, Diesel Doctor, Inc. operates off Highway 2 in Havre, MT, specializing in diesel engine repair. Our facility has all the tools, equipment, and space you need to service big trucks and modern electronic engines. Scott continues to enjoy what he does, and is proud of the relationships the shop has built with truck drivers, farmers, ranchers, and other small businesses in the area. Scott and his team treat people fairly and honestly, ensuring our customers tell their family and friends about Diesel Doctor. In fact, our business—and our reputation—have grown primarily by word of mouth.
