Callos first began providing recruiting services in 1965.  Over the years, the executives we placed requested that we provide more employees for their operations.  Out of those requests, we’ve recruited and provided temporaries for more than 30 years.

With offices in Ohio, Pennsylvania, Maryland, Kansas, and Illinois, Callos is a regional powerhouse in providing temporary employees for many different businesses.  Boasting some of the longest tenure in staff employees in the industry, we have the experience to help your business address all of its hiring needs.
