Of all the high-profile Atlantans chosen for the board of the new nonprofit corporation that runs Grady Memorial Hospital, few, have a more impressive resume than Louis Sullivan, MD. Sullivan is the former secretary of the U.S. Department of Health and Human Services, and brings his connections to the medical world, the Washington bureaucracy, potential donors and to the black community. Credibility in the black community could be key, because many Grady patients are minorities. The hospital's restructuring has been viewed with suspicion by some black leaders who fear it is a power grab by white business leaders.
