Growing up, Bisciotti loved sports. His father took the children to Baltimore Orioles and Colts games. In his senior year at Severna Park High School, he played on the football team, though he has said he "wasn't much of a high school athlete."
In 1982, Bisciotti graduated from Salisbury University in Maryland with a degree in liberal arts. A year later, at 23, he and his cousin Jim Davis started Aerotek, a staffing company in the aerospace and technology sectors. Running the company out of a basement office with secondhand equipment, Bisciotti and Davis produced $1.5 million in sales in the first year. Aerotek grew into the Allegis Group, which is now the largest privately held staffing firm in the United States and 6th in the world. Biscotti's involvement in the sports business has brought more attention to his once low profile company.
One of the first projects Bisciotti directed as owner of the Ravens was to build the team's state-of-the-art training and practice facility, which opened in October 2004.
