Celebrating over 70 years in business In 1938, Charles Britzius opened Twin City Testing in St. Paul, Minnesota. By World War II, Twin City Testing was helping the war effort by testing everything from Navy rope to gun mount bearings.
Reaching across the midwest In 1999, Twin City Testing became part of a network of integrated, independently-operating laboratories, the Stork Materials Technology group. Facilities acquired in Wausau, Wisconsin and Des Moines, Iowa joined Stork Twin City Testing to form a critical hub of testing and inspection activity in the Midwest.
Stork Twin City Testing scientists now provide testing to clients across North America and Canada, while continuing to lead the Midwest in capabilities, experience and diversity.
