Marquardt brought up the idea of starting ATI with O'Brien, at the Kansas City American Royal Barbecue in October 1997, and ATI's doors opened on January 12, 1998. ATI has become an industry leader on commercial and government projects, solving clients' staffing priorities and acting as a true partner. ATI partners with organizations that value the partnership, experience, quality of work, retention programs, benefits and considerations unique to ATI.
