Its founders were Dr. Joseph V. Braddock,[1] Dr. Bernard J. Dunn,[2] and Dr. Daniel F. McDonald,[3] who each received a PhD from Fordham University in the Bronx, New York.

In the early 1960s Tysons Corner was a sleepy crossroads, but has since grown into a classic "edge city", and a home of many government and military contractors.

Tysons Corner and the surrounding towns became the home of many of BDM's competitors, including Planning Research Corporation, DynCorp International, and CACI.
