Our History DMI traces its roots back to the J.L. Healy Construction Company, which incorporated in South Dakota in 1932. For 57 years the company concentrated on Highway Construction, and Utility work within the Midwest. In 1982, Pat Healy, J.L.’s son and CEO of the company, formed the Equipment Distributorship now known as Diesel Machinery, Inc. (DMI). The construction company was sold in 1989 as development of the equipment distributorship advanced. Pat Healy continues to direct the progress of DMI, and customers benefit from his knowledge of equipment and experience in the construction industry. With the help of his son Dan Healy, (President) and Don Mosey (V.P./G.M.), DMI continues to stay focused on achieving its mission.
