STV marked its 100th anniversary in 2012. STV's oldest predecessor firm, Seelye Stevenson Value & Knecht, was founded in New York City in 1912 as Elwyn E. Seelye & Co. as a structural engineering firm. Over the years, the firm's disciplines grew to include mechanical, electrical and civil engineering. The firm performed multi-discipline engineering services throughout the country, working on projects such as the Thomas Jefferson Memorial in Washington, D.C., the parachute jump at the 1939 World's Fair, NASA's Vehicle Assembly Building at the Kennedy Space Center in Florida, and the Enrico Fermi National Accelerator Laboratory in Batavia, Illinois.

Sanders & Thomas, another predecessor firm of STV's, was founded in Pennsylvania in 1945. Sanders & Thomas performed process and industrial engineering and was best known for its military and industrial work. Sanders & Thomas merged in 1968 with Voss Engineering Company, a manufacturer, to form STV, Inc., a management holding company established to acquire other firms that would later evolve into the present-day STV Group.

In 1983 STV acquired Lyon Associates, which enhanced STV’s international capabilities with offices in several key foreign cities. In 1990, STV Environmental and STV Architects were established to increase the firm's abilities within those fields. STV Construction Services was formed in 1994. Also in 1994, the acquisition of STV/Silver & Ziskind added specialized architectural expertise in criminal justice, education, and health care facilities. In 1995 Seelye Stevenson Value & Knecht, Sanders & Thomas and Lyon Associates were renamed STV Incorporated and merged into one company, STV Incorporated (STV), which is headquartered in New York City. STV Group, the parent company, is headquartered in Douglassville, Pennsylvania.

On August 29, 2001, STV Group's employee and public shareholders approved a proposed transaction to take the firm private with a single owner, the company’s Employee Stock Ownership Plan. Today, STV is a 100 percent employee-owned firm. In 2006, STV acquired Ralph Whitehead Associates (RWA), a consulting civil and transportation engineering firm based in Charlotte, North Carolina, to extend the corporation's geographic reach into the Southeastern United States as well as its capabilities in the bridge engineering and freight operations.
