A. Steve Arizpe, Administaff’s executive vice president of client services, said, "This alliance allows us to more fully develop our service model for larger clients by working closely with a trusted business partner.

Gil Marmol, Luminant’s chief executive officer, commented, "We are pleased to have the opportunity to elevate our relationship and become a strategic partner.
