Spherion
A North American staffing and workforce-solutions business formerly known as SFN Group and later acquired by Randstad.
Last updated August 26, 2026
Overview
Spherion was a North American staffing and workforce-solutions company whose history began in Chicago in 1946 as City Car Unloaders. Founded by Leroy Dettman and Joseph Perfetto, the original business placed manual laborers into temporary jobs, especially cargo-loading work. It later expanded into clerical and administrative placements, establishing the basic temporary-staffing model that became central to the company. The business moved from Chicago to Fort Lauderdale, Florida, in 1969. By 1978 it operated as Personnel Pool of America, Inc., and that year it was acquired by H&R Block. H&R Block subsequently acquired Interim Systems Corporation in 1991 and combined it with Personnel Pool, creating a larger staffing-services operation. The combined business adopted the name Interim Services Inc. in 1992 and was spun off from H&R Block in 1994. After the spin-off, Interim Services pursued an acquisition-led expansion strategy. The company acquired staffing and professional-services businesses in several segments and, in 1997, acquired the London-based Michael Page Group. In 1999 it acquired Norrell Corp., an Atlanta-based staffing rival. The expansion broadened the company's geographic reach and service mix beyond traditional temporary labor, including office staffing, professional recruitment, information-technology staffing, healthcare placements, and recruitment-process outsourcing. The company changed its name to Spherion in 2000. The period around the Norrell acquisition also involved a strategic debate over corporate headquarters and management direction. Raymond Marcy, who had led the business for more than a decade, was replaced as chief executive by Cinda Hallman in 2001. Spherion subsequently completed an initial public offering of its London-based Michael Page Group subsidiary in 2001 and sold the Saratoga Institute to PricewaterhouseCoopers in 2003. Spherion operated through multiple brands and specialist units, including Spherion Staffing Services, The Mergis Group, Tatum, Technisource, Sourceright Solutions, and other regional or professional staffing names. The portfolio reflected the company's attempt to serve both high-volume temporary staffing customers and employers seeking specialized recruiting, professional placement, or outsourced workforce-management services. The business also used the SFN Group name in its corporate history and brand architecture, which is the source of the supplied SFN Group identification. Randstad N.V. acquired Spherion in July 2011. Following the acquisition, Spherion ceased to exist as an independent publicly traded company and its operations and brands were integrated into Randstad's broader staffing and human-capital-services organization. Later leadership references associated with the Spherion business include Rebecca Rogers Tijerino, who became chief executive in January 2019, and Kathy George, who replaced her in February 2024. Because the historical Spherion entity was acquired and absorbed into Randstad, it is best treated as a defunct standalone corporate brand rather than an independent current company.
History
Spherion originated in 1946 as City Car Unloaders, a Chicago temporary-labor company established by Leroy Dettman and Joseph Perfetto. Its initial business focused on placing manual laborers in short-term cargo-loading jobs. The company later added clerical placements, beginning a shift from a narrowly industrial labor service toward a broader employment agency. The company relocated to Fort Lauderdale in 1969. In 1978 it was operating as Personnel Pool of America, Inc. and was acquired by H&R Block. H&R Block expanded the operation through the 1991 acquisition of Interim Systems Corporation. Personnel Pool and Interim Systems were combined, producing a larger staffing-services business that changed its name to Interim Services Inc. in 1992. H&R Block spun off Interim Services in 1994. As an independent company, Interim pursued an aggressive acquisition strategy intended to increase its scale and add specialized staffing capabilities. It acquired the London-based Michael Page Group in 1997 and Atlanta-based Norrell Corp. in 1999. These transactions expanded the company's geographic coverage and helped it compete in professional recruitment as well as temporary staffing. The company changed its name to Spherion in 2000. The Norrell transaction contributed to a debate within the company's board about moving its corporate headquarters from Fort Lauderdale to Atlanta. The governance dispute coincided with a leadership transition: Raymond Marcy, who had served as chief executive for more than a decade, was replaced by Cinda Hallman in 2001. That year, Spherion completed an initial public offering of its London-based Michael Page Group subsidiary. In 2003, it sold the Saratoga Institute to PricewaterhouseCoopers. Spherion developed a portfolio of brands aimed at distinct portions of the employment market. Its names included Spherion Staffing Services, The Mergis Group, Tatum, Technisource, Sourceright Solutions, and Spherion Recruitment Process Outsourcing, alongside other regional and specialist brands. The portfolio covered temporary and contract employment, office and administrative placements, professional recruitment, information technology, healthcare, and recruitment-process outsourcing. SFN Group was also used in the company's corporate and brand history, although the canonical Wikipedia subject is Spherion. Randstad N.V. acquired Spherion in July 2011. The acquisition removed Spherion from the public market and ended its status as an independent corporate group. Its businesses and brands were subsequently incorporated into Randstad's wider human-resources and staffing platform. Later leadership information identifies Rebecca Rogers Tijerino as chief executive from January 2019 and Kathy George as her successor from February 2024. The historical entity is therefore most accurately described as a former North American staffing company and brand operating within the Randstad lineage.
