Former Tennessee Gov. Phil Bredesen has joined the board of Vanguard Health Systems, an operator of 28 hospitals and complimentary facilities and services. "The addition of Phil to the board will further diversify the outstanding talents and wide-ranging experience that our directors already bring to Vanguard," said Charlie Martin, chairman and chief executive of Nashville-based Vanguard. Bredesen brings experience as a healthcare entrepreneur and from overseeing changes to the state's Medicaid program, TennCare, during his tenure as governor. He also is the author of the book Fresh Medicine: How to Fix Reform and Build a Sustainable Health Care System and speaks to national audiences on healthcare, political leadership, and other topics.
