NEW YORK — Joseph Baker has been hired as president of the Medicare Rights Center, a national nonprofit consumer organization that works on access to health care for older adults and people with disabilities. Baker served as a senior policy advisor in the administrations of New York Govs. David Paterson and Eliot Spitzer. "We are thrilled to have Joe Baker take the helm of the Medicare Rights Center at a time when fundamental reforms to our health care system are on the national agenda," said MRC Board Chairman Bruce Vladeck, former administrator of the Health Care Financing Administration (CMS' predecessor) in the Clinton administration. Baker replaces Robert M. Hayes, who stepped down in February after seven years as president and general counsel.
