Susquehanna Truck Service was founded in 1981 by William W. Greek and David M. Greek in Holtwood, Pennsylvania. William Greek, owned a trucking company where David Greek, (William's Son), worked on his father’s equipment. This sparked the interest and motivation to open his very own business venture.

Susquehanna Truck Service started out by performing general truck repairs and doing some engine repair and rebuilding. In 1985, Susquehanna moved to a new location in Quarryville, PA that was large enough to hire a few employees, and stock some parts. As the business grew and became popular, it was necessary to find a bigger location again. In 1996, Susquehanna Truck Service built a 12,000 square foot shop that is still being utilized today. In 2018, Susquehanna Truck Service built and opened a 10,400 square foot shop as an expansion on the same property. Between the two buildings, it houses a large amount of parts inventory for over the counter sales and redistribution, specialized testing equipment, and retains 25 employees..
