About the McCallum League
Bill Stoller, Founder & Late CEO of Express Employment International
William H. Stoller was the Founder, CEO, and Chairman of the Board of Express Employment International. A trailblazer in the staffing industry, Bill began his career in 1973 as a consultant trainee with Acme Personnel Services, where he quickly advanced through leadership roles before co-founding Express.
Beyond Express, Bill served as CEO of The Stoller Group, owning multiple Express Employment Professionals, Express Healthcare Staffing, and Specialized Recruiting Group franchises across Oregon, Washington, Arizona, Nevada, and Colorado. His entrepreneurial vision extended into other ventures including Xenium HR, Stoller Family Estate, Chehalem Winery, and Evergreen Aviation & Space Museum.
Bill was more than a leader—he was a builder of opportunity. With quiet strength and genuine care, he created a foundation that touched millions of lives and will continue to inspire future generations. At NexGenPreneur and across the McCallum League, we carry on his mission every day: helping as many people as possible find good jobs by helping as many clients as possible find good people.
