EMS was established in 1994 as a division of CBS Personnel Services, held by a publicly traded company. We are a part of a full service staffing firm, one of the largest in the U.S. EMS currently provides services to over 200 clients and 4,600 client employees. Due to the financial stability of our company, EMS is the only co-employer organization in the state of Ohio to have a self-insured workers' compensation program. Our commitment to service and quality is demonstrated through our National Association of Professional Employer Organization (NAPEO) membership.
