William Foley rejoined Huron Consulting Group after stints with Vanguard Health Systems and Cook County (Ill.) Health and Hospitals System.
Foley, 62, worked with Huron from 2007 until 2009, when he was hired as the first CEO of Cook County's public hospital system after the county board voted to give it an independent governance structure. He resigned in 2011 to lead Vanguard's four Chicago-area hospitals.
The Nashville-based chain, which was acquired this year by Dallas-based Tenet Healthcare Corp., removed Foley in July in a management shuffle carried out while the deal was pending.
Foley is now a managing director with Huron Healthcare's practice focused on public hospitals, systems and academic medical centers. He will work with those clients on performance improvement, strategy and governance.
