Since its creation in 1922, MHA has grown from 50 to more than 150 member hospitals. As a not-for-profit membership association, MHA represents every acute care hospital in the state, as well as most of the federal and state hospitals and rehabilitation and psychiatric care facilities.Just as our member hospitals have broadened their scope to embrace the continuum of health care services, MHA also has expanded its services to members throughout its history. In addition to representation and advocacy on behalf of its members, the association offers continuing education programs on current health care topics and seeks to educate the public and the media, as well as legislative representatives, about health care issues.
