Company Background

Aerotek was founded in 1983 in Baltimore, MD by entrepreneurs Steve Bisciotti and Jim Davis. It got its start by providing engineering staffing for the aerospace and defense industries and later for automotive manufacturers and suppliers. In 1990, the company formed Telecommunications Services, now known as TEKsystems, which has been recognized as the top information technology staffing firm in the US by the IT Services Business Report.

In 1993, Aerotek acquired Onsite Engineering & Management focused on environmental and energy services staffing. It later branched out to include staffing for other industries including biotechnology, pharmaceuticals, healthcare, light industrial, and light technical. It opened its first European office in 1993 and two years later, expanded into Canada with an office in Mississauga, Ontario.

In 1998, Allegis Group was formed as the parent entity of several operating companies, including Aerotek, TEKsystems, and Onsite. In 2001, Aerotek and Onsite merged to become Onsite Companies and in 2004, Onsite Companies changed its name to Aerotek, Inc., to leverage the reputation of the Aerotek name.
