TT&D Trucking was formed in 1996 by David L. Houston. The company started hauling pulpwood and tissue paper in West Alabama. In 2000, Tarrence Houston joined the organization and the company began to focus on dedicated transport. TT&D was then retitled to Sigma Logistics Inc. In 2003, our company added refrigerated transport to our portfolio. The first dedicated contract was with Peco Foods, hauling poultry from Tuscaloosa, AL to all major ports in the South Eastern United States. With a high level of customer satisfaction, Sigma Logistics has grown to be a $7M carrier with 30 trucks covering the Midwest and Southern half of the United States. Our core customers are Royal Foodservice, Golden State Foods, Perrigo Pharmaceuticals, and Meat Commodities, Inc.
