Wexford Health Sources, Inc. is a healthcare services company headquartered in Foster Plaza Two in Green Tree, Pennsylvania, near Pittsburgh. The Mississippi Department of Corrections (MDOC) contracts with Wexford, and Wexford provides medical services to inmates at state-operated facilities. In 2008 Steve Twedt of the Pittsburgh Post-Gazette said that Wexford was "among the most successful local companies people never hear about," despite the fact that the former chief executive of Allegheny County, Jim Roddey, described by Twedt as "one of the region's most prominent local politicians," headed the company. As of that year the president of Wexford, Mark Hale, said that he tries to keep a low profile because the inmates the company serves are very litigious.
