Founded1950

Olsten Staffing Services, founded in 1950 by William Olsten, was a major American temporary staffing agency. It grew to become one of the largest staffing firms globally, offering a wide range of services including temporary and permanent placement, professional staffing, and managed services across various sectors like office administration, light industrial, healthcare (Olsten Health Services), and information technology. In a landmark deal within the staffing industry, Olsten Corporation was acquired by Adecco S.A. in March 2000 for approximately $1.6 billion. This acquisition significantly expanded Adecco's footprint in North America. While the Olsten brand has largely been integrated into Adecco, its legacy contributed to shaping the modern staffing industry.
