Chuck Hays, chief executive officer of MaineGeneral Health in Augusta, was installed as chairman of the Maine Hospital Association board of directors at the association’s annual Summer Forum on Wednesday at the Samoset Resort in Rockport.

According to a news release from the Maine Hospital Association, Hays succeeded James Donovan, CEO of LincolnHealth in Damariscotta, who is now immediate past chairman.

Peter Sirois, CEO of Northern Maine Medical Center in Fort Kent, is now chairman-elect; and Charles Therrien, CEO of Maine Coast Memorial Hospital in Ellsworth, is the new board treasurer. R. David Frum, president of Bridgton and Rumford hospitals, becomes board secretary.

Hays joined what is now MaineGeneral Health in 1995 as director of engineering. In the more than 19 years since Mid-Maine Health System joined Kennebec Valley Health System to become MaineGeneral Health, Hays has held positions of increasing responsibility with the state’s third-largest health care system.

As senior vice-president and chief operating officer, Hays headed the team responsible for the construction and operation of the Harold Alfond Center for Cancer Care, which opened in July 2007. MaineGeneral opened a new $312 million hospital in November 2013.

In October 2007, Hays was named president and CEO of MaineGeneral Medical Center, becoming president and CEO of the parent company, MaineGeneral Health in 2012.
