Making business simple is our goal

In 1969, Bill Guss moved his family from New York to Hawaii with every intention of retiring. It was nice… for about a week. Restless, Bill noticed how much trouble a Navy shipyard was having in finding quality, productive workers for short-term projects.

Bill couldn’t resist the opportunity, and as a result, Labor Services, Inc. was born. At the company’s original location near Waikiki Beach, Bill raised a flag outside of the building in the morning to signal nearby surfers that work was available that day.

The business grew quickly. As the company’s clients faced new business challenges, the Guss family found new business solutions—clerical staffing, receivables management, and outsourced human resources services.

Each business line had one idea in common: Making business simple. It made sense to bring all of these business tools together under one roof. And so in 1993, the group of family-owned businesses became ALTRES: ALTernative RESources for Business.

In 2001, a corporate headquarters and service center was built on Kapiolani Boulevard to house their two Honolulu-based business units, ALTRES Staffing and simplicityHR by ALTRES.

Today, ALTRES Staffing is Hawaii’s largest staffing and recruiting company, with six offices across the state, and simplicityHR by ALTRES serves as the human resources “back office” for more than 2,200 local businesses. For over 50 years, we’ve been Hawaii’s #1 HR outsourcing company.

Company Timeline


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.


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.


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.


The ALTRES companies expand from Hawaii to the mainland, opening up and buying businesses in California, Arizona and Utah.


ProEmp Journal names us the #1 professional employer organization (PEO) in America.

Our company becomes one of the first PEOs to be accredited by the Employer Services Assurance Corporation, demonstrating our industry leadership and adherence to strict financial, operational and ethical standards.


After 15 years of continuous expansion and growth outside of Hawaii, we decide to focus exclusively on serving the Hawaii business community once again.


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.
