History

Thompson Electric Company was founded by Alfred C. Thompson in Sioux City, Iowa, in 1933.

He dedicated his company to the simple principle of providing quality services and products to his customers, his employees and his community. With his vision, the company developed into a strong, well-financed corporation ranked among the top Midwest electrical contractors.

Throughout its history, Thompson Electric has always advanced as an industry leader in the introduction and implementation of new technologies such as Autocad, 3D CAD, BIM, Revit, Design-Build, Prefab, Infrared Thermal Imaging, Arc Flash Risk Assessment, Alternative Energy, project coordination, comprehensive safety programs, and integrated computer estimation, accounting and management systems.

These advancements and philosophies earned Thompson Electric the trust and loyalty of a growing customer base. To support this growth, the company expanded and maintains permanent offices in Omaha, Nebraska, and Sioux Falls, South Dakota, in addition to Sioux City.

Today, Thompson is still dedicated to providing innovative electrical contracting, technology, electrical safety, automation, and robotics expertise to a wide variety of markets throughout the Midwest.
