Oasis Outsourcing, the nation’s largest privately held Professional Employer Organization (PEO), has announced the acquisition of Aureon HR, a subsidiary of Aureon. Headquartered in West Des Moines, IA, Aureon HR has been a leading Midwest-based HR outsourcing company with a reputation for superior customer service for more than 30 years.

The combined company will now serve more than 8,000 clients and 270,000 worksite employees nationwide. Terms of the deal were not disclosed.

“We are delighted to join forces with Aureon HR, an industry leader that has an outstanding track record in the Midwest and in all markets it serves,” said Mark Perlberg, President and CEO of Oasis Outsourcing. “In addition to significantly expanding our national client base, Aureon HR brings Oasis best-in-class HR expertise in the Senior Living industry, and yet another talented, experienced group of associates, who will make important contributions to our overall ongoing expansion and growth.”

“Oasis has built a strong and reputable business with great talent and, like Aureon HR, has an unwavering commitment to great service and innovation,” said Ron Keller, CEO of Aureon. “Moving forward, Aureon HR clients will receive the benefits that an even larger industry leader can provide, while continuing to receive outstanding performance and support from the local Aureon HR team.”

The Aureon HR acquisition is Oasis’ sixth since joining forces with Stone Point Capital nearly four years ago. Aureon HR will continue to operate from its current locations in West Des Moines, IA and Denver, CO with the current team of associates.
