We believe that every business leader should have the opportunity to focus on serving their clients and growing their business, leaving the administrative duties of being an employer—including HR, payroll and benefits administration—to us.
Xenium is an HR & Employer Services company in Tualatin, Oregon. Our team of HR and payroll professionals support small- and medium-sized companies that have limited or no internal HR resources, as well as companies with internal HR staff who can benefit from support and training.
We view people as an organization’s biggest asset. From developing competitive people practices to carrying out tough employer decisions, our team supports business leaders to provide them freedom to focus on growing their business.
Xenium began more than 20 years ago as a division of Express Employment Professionals offering integrated human resources, payroll and benefits services to small northwest businesses. In 2000, Xenium formed a separate corporation under The Stoller Group and our growth accelerated. We added HR consulting services, expanded our training offerings, and by 2008 we tripled in size. In 2009, we added integrated HR and payroll (ASO) to our PEO and HR Consulting business, and have since doubled in size. Many of our team members and clients who started with us in the early days of Xenium are still with us today. As we continue to grow and expand, we challenge ourselves to provide the highest quality service by focusing on our relationships with team members and clients.
Because at the end of the day, it’s about people.
The Xenium staff is active in a variety of professional organizations. These organizations include the National Association of Professional Employer Organizations (NAPEO), the Society for Human Resource Management (SHRM), the Northwest Professional Employer Association (NWPEA) and the American Payroll Association (APA). Maintaining our skills through continuing education and participation in professional organizations gives Xenium clients an added level of expertise.
Xenium has been a member of the National Association of Professional Employer Organizations since 2000. NAPEO, based in Alexandria, Virginia, is the recognized “Voice of the PEO Industry®.” NAPEO has more than 700 PEO members found in all 50 states, representing more than 70 percent of the revenues of the $68 billion PEO industry. PEOs enable clients to cost-effectively outsource the management of human resources, employee benefits, payroll and workers’ compensation. This allows PEO clients to focus on their core competencies to maintain and grow their bottom line.
The Society for Human Resource Management (SHRM) is the world’s largest association devoted to human resource management. Representing more than 210,000 individual members, the Society’s mission is to serve the needs of HR professionals by providing the most essential and comprehensive resources available. As an influential voice, the Society’s mission is also to advance the human resource profession to ensure that HR is recognized as an essential partner in developing and executing organizational strategy. Founded in 1948, SHRM currently has more than 550 affiliated chapters and members in more than 100 countries.
The American Payroll Association is the professional society for Payroll Professionals. Founded in 1982 it is run by a professional staff under the direction of the Executive Director, the member President, and Board of Directors. The Association pursues the following objectives: To increase the Payroll Professional’s skill level through education and mutual support, to obtain recognition for payroll work as practiced in today’s business and legislative environments and as a professional discipline, to represent the Payroll Professional on the federal, state and local level and to provide public service education on payroll and employment issues.
