Engineering consulting firm Terracon announced the acquisition of Skelly and Loy (S&L), headquartered in Harrisburg, Pennsylvania.

“S&L’s environmental and engineering expertise and long-time regional presence allows us to further strengthen our service offerings and geographic resources in Pennsylvania and the Mid-Atlantic,” says Gayle Packer, Terracon president and CEO. “By joining forces, our shared capabilities and focus on outstanding client experience allows us to bring even greater resources to clients regionally and nationally.”

Founded in 1969, S&L is a privately held environmental consulting and engineering services company. It has more than 50 years serving public- and private-sector clients in the Mid-Atlantic region.

S&L’s 150 employees will become part of Terracon, serving clients from offices in Harrisburg, Pittsburgh, and State College, Pennsylvania; Hagerstown and Hunt Valley, Maryland; and Morgantown, West Virginia. The organization will continue to serve clients locally as Skelly and Loy, A Terracon Company.
