Founded in 1948, Robert Half is the first business to provide specialized staffing services for accounting and finance professionals. The company's CEO, Harold M. "Max" Messmer, has led Robert Half's expansion from $7 million in annual revenues in 1986 to $4.2 billion in 2013.

Back in 1986, the idea of the professional-level temporary was still untested, as the industry was primarily made up of generalist staffing firms placing clerical and light-industrial workers. Believing that companies would be open to temporary workers at higher skill levels, Robert Half launched a series of new professional staffing divisions, all of which have grown into highly successful businesses. In later years, other companies saw the value in this approach, and professional-level staffing is now the fastest-growing segment of the staffing industry.

In 2013, Robert Half celebrated its 65th anniversary in business. In those six and a half decades, the company has built a stellar reputation for high ethical standards, a specialized focus and unparalleled service. As one of the only truly global specialized staffing firms focusing exclusively in professional positions, Robert Half continues to help businesses worldwide find the skills they need, while assisting untold numbers of job seekers in finding meaningful employment.
