About Us

Wyoming Diesel Service (WDS) was started as a sole proprietorship in 1968 by James W King (Butch) when he became certified as an Automotive Dealer for Cummins Engine Co. WDS has maintained and grown with this certification to the present day. In 1988 WDS became a certified Caterpillar Truck Engine dealer; this too continues to be a beneficial part of the company’s success. WDS was incorporated in 1994 and still operates as a closed corporation registered within the state of Wyoming.

Butch was joined by his son James M King (Jim) to help with the business in 1985. The company has changed the way it is structured over the years but is still family owned and managed. 1994 marked Butch’s retirement and Jim taking over the day to day management which he is still in charge of today.
