Customer testimonials

A few of the nice things our customers have to say about SMT

Hands down, SMT is the best intra-tx carrier in our arsenal and it is always a pleasure working with them.
SMT's service, transit time, and pricing is accurate and consistent. The ability to speak directly to their dispatchers or managers provides a sense of reliability.
They allowed us to pick up our freight at the dock. It was fast and convenient. Everything was in great shape and the employees were so nice!
