Coleman Engineering, Inc. was founded in 1975 in Memphis, Tennessee by T. H. Coleman, Sr. and T.H. Coleman Jr., owners of Vico GM Diesel. In 1975, Vico was sold, with the shareholders retaining the manufacturing division that built portable floodlighting equipment (light towers) and diesel powered AC generator sets. This manufacturing division became Coleman Engineering, which relocated in 1996 from Memphis, Tennessee to it’s present location at 835 Highway 178 East in Holly Springs, Mississippi.
