On Assignment Lab Support Marks 20-Year Milestone.

CALABASAS, Calif. -- On Assignment, Inc. (NASDAQ:ASGN), a leading provider of life sciences and healthcare staffing solutions, today announces its 20th year anniversary of providing skilled contract and permanent placements worldwide.

Beginning as a small scientific staffing firm in 1985, On Assignment Lab Support made its mark as a leader in placing quality scientific professionals. After 20 years, On Assignment Lab Support continues to set the standard in the scientific staffing industry assisting over 5500 scientists to find their desired career opportunity in 2004 throughout the United States and United Kingdom, Belgium and the Netherlands.

Inventing the scientists for scientists approach, the On Assignment vision was to create the first nationwide scientific staffing firm with trained scientists who hire scientists. The model was simple. Give clients everything they need and more with a practical price point, as well as bring the opportunities that are so difficult for scientists to find -- working on the innovations of tomorrow. As the only staffing firm to employ scientists in both sales and recruiting, the model offers clients and candidates confidence due to the credibility of the On Assignment Lab Support staff they speak with every day.

"We place scientific professionals at each stage of our clients' product lifecycle including R&D, preclinical, clinical trials, regulatory, production as well as validation and compliance," said Emmett McGrath, President of On Assignment Lab Support. "And we do this from entry level to senior scientists, managers and directors. In support, we take the best path for both our clients' needs and our candidates' careers whether the position is contract, contract-to-hire or direct placement."

After many years of successful growth, On Assignment saw the opportunity and the need to expand. This decision brought forth new lines of business including Healthcare Staffing, Nurse Travel, Clinical Research, Engineering, Health Information Management, and Allied Travel, all of which achieved significant growth in the past year.

"Entering our twentieth year, I would be remiss if I did not take a moment to visit our past as we embrace our future," said Peter Dameris, President and Chief Executive Officer of On Assignment. "As we enjoyed the success of the '90s and the turn of the century, we saw the need to add as well as modify practice areas, and I am very encouraged with the future that lies ahead."

"I am flattered to see the innovations and trends that On Assignment Lab Support creates mirrored throughout the staffing industry," said McGrath.

Since its launch in 1985, On Assignment has always defined its success by the people who make up the company. With that philosophy and the future of staffing in mind, the People First approach was introduced in late 2004. People First emphasizes the company mission to assure clients get the best person for the job, and our employees get the best opportunity for their skill set.

"Our team of talented professionals proves the greatness of this company to our clients, our recruits, our working employees as well as to each other," said Dameris.
