Thompson Electric Company was founded by Alfred C. Thompson in 1933, in Sioux City, Iowa. He dedicated his company to the simple principle of providing quality services and products to his customers, his employees, and his community.  More than 75 years later, this basic priciple remains the key to our success.  We are proud to be ranked among the top Midwest electrical contractors. Throughout its history, Thompson Electric has been an industry leader in the introduction and implementation of new technologies such as Autocad, comprehensive safety programs, and integrated computer estimation, accounting and management systems.
