Stanley was founded as a small consulting firm in 1966 by Rear Admiral Emory D. Stanley. For the next 20 years, the company continued as a two-man consulting business focused on maritime studies. The company’s success, which has been built on a culture that emphasizes a commitment to strong, long-term partnerships, integrity in everything we do, and results for our customers, is exemplified by its proven track record. All major contracts have been recompeted and retained at least once, and new customers and services have been added each year.

In 1996, Stanley's management introduced an Employee Stock Ownership Plan as an exit strategy for the departing founders and to further enhance its employee-focused culture. Stanley has approximately 3,500 employees at locations across the United States and around the world. In 2005, Stanley was named the mid-sized Government Contractor of the Year by the Northern Virginia Government Contractors Council, the Professional Services Council, and Washington Technology. In 2007 and 2008, Stanley was recognized by FORTUNE® magazine as one of the “100 Best Companies to Work For.”

Stanley has made five acquisitions within the past eight years and implemented a formalized acquisition program, which has been instrumental in making these companies feel welcome within our organization. In February 2006, Stanley acquired Morgan Research Corporation, expanding our offerings to the U.S. Army and our presence in Huntsville, AL, and adding NASA as a new customer. Most recently, in April 2007, Stanley acquired Lawton, Oklahoma based Techrizon, LLC, a premier provider of software, training, simulation and information security solutions. This acquisition reinforces Stanley's strategy to expand its presence in key markets positively impacted by the Base Realignment and Closure (BRAC) process.
