Professional employer organization Oasis Outsourcing, one of the largest PEOs in the US, announced Kelley Castell joined the company as COO, effective Sept. 19. This is a new role within the firm.

Castell previously was senior VP of client services and portfolio management for First Data Corp. He has also had a long military career as an officer in the US Navy, and currently serves as the executive officer of the Naval Cooperation and Guidance for Shipping Unit in San Diego.
