Southeastern Freight Lines, a privately-owned company, has been a trusted name in South Carolina’s business community since its founding in 1950. Established in Columbia by W.T. Cassels, Sr., the company began with 14 trucks, 20 associates, and a $5,000 loan. From the very beginning, Cassels emphasized a simple yet powerful philosophy: “If you take care of your people, they will take care of the customer, and that will take care of the future.”
Known for its dedicated people and its signature “Quality Without Question” service, Southeastern has grown into a leader in regional less-than-truckload (LTL) transportation. The company is headquartered in Lexington, South Carolina, where over 500 associates support critical functions. From operations, sales, and human resources to fleet services, information technology, real estate, finance, pricing, and beyond – these teams support the field of drivers and associates who keep the wheels of the economy turning.
With 8,500 associates, Southeastern handles around 8.6 million shipments annually and generates over $1.7 billion in revenue. The company’s 89 state-of-the-art service centers span the Sunbelt and Puerto Rico, with partnerships extending across 36 additional states, Canada, Mexico, and the U.S. Virgin Islands. Southeastern also offers specialized Final Mile delivery solutions, catering to unique locations without traditional docks.
Community involvement is central to Southeastern’s culture. Through its SERVES program, associates and their families have contributed over 34,000 hours of volunteer work since 2012, supporting causes such as veteran organizations, homeless shelters, and domestic abuse shelters.
Sustainability is also a priority, with ongoing initiatives to improve fuel efficiency, reduce waste, and increase the use of renewable resources. These efforts reflect the company’s commitment to protecting the environment and supporting the communities it serves.
Proudly rooted in South Carolina, Southeastern Freight Lines remains focused on prioritizing people and delivering unmatched quality year after year.
