On Assignment, Inc. (NYSE: ASGN) is a leading global provider of in-demand, skilled professionals in the growing technology, healthcare, and life sciences sectors, where quality people are the key to success. 

The Company goes beyond matching résumés with job descriptions to match people we know into positions we understand for short- and long-term placement of contract, contract-to-hire, and direct hire professionals. Clients recognize On Assignment for our quality candidates, quick response, and successful assignments. Professionals think of On Assignment as career-building partners with the depth and breadth of experience to help them reach their goals.

With nearly three decades of experience, On Assignment focuses on positions that advance our clients’ competitive advantage while remaining the employer of choice for professionals at various stages in their career. Our success can be attributed to never losing sight of the people involved in the process of staffing. It is the simple, yet remarkably effective, difference in our People First Approach.

On Assignment was founded in 1985 and went public in 1992. Our corporate headquarters is located in Calabasas, California, with a network of approximately 130 branch offices throughout the United States, Canada, United Kingdom, Netherlands, Ireland, and Belgium. Additionally, physician placements are made in Australia and New Zealand.

The Company's strategy is to focus on expanding its current service offerings through organic growth and acquisitions while capitalizing on the high-growth areas within the markets we serve. While continuing to identify the right opportunities for expansion, On Assignment is focused on ensuring it remains the provider of choice for clients and the employer of choice for professionals looking for temporary and permanent positions.

On Assignment History
The Company opened its doors in 1985 as Lab Support, providing contract staffing and direct hire placements to organizations within the scientific community. Lab Support's focus on scientific staffing created a niche service offering with dedicated teams who specialize in serving specific industries. This philosophy is still the core of our expanded service offerings today, and differentiates the divisions of On Assignment from many other staffing firms, helping us achieve some of the highest margins in the industry.

To facilitate further expansion of our business, On Assignment, Inc. went public in 1992, trading on NASDAQ under the ticker symbol ASGN.

After nearly ten years in scientific staffing, On Assignment expanded into healthcare staffing with original offerings in the area of healthcare financial. Our Healthcare Segment has since grown to provide a vast array of services, placing professionals in areas, including nursing, physician, respiratory therapy, rehab therapy, pharmacy, office/administration, dental, clinical laboratory, diagnostic imaging, and health information management (HIM).

The original growth of the Healthcare Segment can be attributed to the acquisition of Health Personnel Options (HPO) in 2002. Prior to the acquisition, HPO was a leading provider of healthcare staffing services that specialized in travel nursing, allied travel professionals, and local staffing.

In 2003, the Company expanded once again when our Clinical Research and Engineering divisions were established. These divisions along with Lab Support formed our Life Sciences Segment, placing professionals in a wide range of industries, including biotechnology, medical device, pharmaceutical, food and beverage, environmental, chemical, and consumer care as well as government and academia.

In 2007, the Company further expanded by acquiring VISTA Staffing Solutions, a leading provider of physician staffing, including domestic and international locum tenens, extended placement, and permanent physician search and consulting. This same year, On Assignment acquired Oxford Global Resources, an international provider of high-end IT and engineering staffing.

Continuing to strengthen our life sciences offerings, the Company acquired The Cambridge Group and Sharpstream Life Sciences in 2010. At the time, The Cambridge Group provided recruitment, staffing, and job placement services in the areas of clinical research, IT, and physician. Sharpstream continues to offer search services for executive to middle managers in life sciences. 2010 also marked On Assignment's 25th anniversary – Putting People First since 1985.

In 2011, On Assignment acquired Valesta, a provider of clinical research professionals in Western Europe. The expansion strengthened our global presence in life sciences staffing, and enhanced our clinical research business internationally. The Company has since rebranded its clinical research division under the name Valesta Clinical Research Solutions.

In 2012, the Company acquired Apex Systems, a mid-level IT staffing company that perfectly complements the existing high-end IT offerings of our technology division, Oxford Global Resources. The transaction made On Assignment one of the largest professional staffing firms and the third largest IT staffing firm in the United States. 2012 also marked On Assignment’s 20th anniversary as a publicly traded company – originally traded on NASDAQ, the stock offering was transferred to NYSE in 2012.

On Assignment remains committed to our founding principles of diversification and a focus on in-demand math and science skills to meet the evolving needs of the global economy, and provide for our continued growth.
