TMC Transportation - NOT TN/Career Site

In 1972, Harrold Annett purchased the dormant trucking company, The Mickow Corporation. On March 6, driver Wally Harrah delivered TMC’s first load from Chicago to Des Moines. With six power units and an office staff of two, Harrold and his team of professionals built TMC into the largest privately-held flatbed carrier in the nation.

TMC’s headquarters in Des Moines, Iowa are set on a picturesque 50-acre campus which includes state-of-the-art training and maintenance facilities, Black and Chrome Truck Sales and the up-scale Baymont Inn and Suites, the industry’s first driver hospitality center.

The industry’s premier flatbed carrier, TMC is known for its integrity, innovation, highly-trained drivers, impeccably maintained late-model equipment, superior safety record and unwavering dedication to quality and customer service.
