About Us

Founded in 1976 by Doug Wayne, D&W Diesel was originally named D.W. Auto Electrical Inc. and operated out of a rented one-bay garage. The business was focused on diagnosing and repairing electrical problems on cars and trucks, and rebuilding rotating electrical components. Three years later Doug’s brother Dave joined the company.
