Who We Are

Company Timeline

Timeline of simplicityHR by ALTRES

1969 Bill Guss opens a labor services company to provide a flexible workforce to Oahu shipyards. From his office lanai in Waikiki, he would raise a blue flag just after sunrise—a sign to surfers on dawn patrol that there was work available that day.
1971 The East Coast corporate headquarters of Xerox, IBM and Motorola find it difficult to provide payroll and HR support to their Hawaii-based employees 5,000 miles away. We fill a need and pioneer the outsourcing of HR administration in Hawaii.
1981 We establish Hawaii’s first professional employer organization (PEO) and becomes a national leader in the PEO industry, providing HR administration and support services to both commercial and nonprofit clients.
1988 The ALTRES companies expand from Hawaii to the mainland, opening up and buying businesses in California, Arizona and Utah.
2000 ProEmp Journal names us the #1 professional employer organization (PEO) in America.
2003 After 15 years of continuous expansion and growth outside of Hawaii, we decide to focus exclusively on serving the Hawaii business community once again.
2008 We reach the milestone of 5,000 worksite employees. This is the total number of client employees on six islands who receive their paychecks, health care plans, employee benefits, and worker's compensation coverage through ALTRES.

We celebrate our 40th anniversary and for the 5th consecutive year, we are ranked one of Hawaii’s Best Places to Work.

We reinvent our HR division as simplicityHR and become the first provider in the nation to provide multiple tiers of HR administration services.

We are named “Innovative Company of the Year” by Pacific Business News.

2011 We release  HR Symphony®,a fully-integrated, single-login, human resources information system (HRIS) and web portal.
2012 We acquire KilaKila Employer Services, Maui's leading PEO.
2013 We introduce the HR Symphony® mobile app.
