Hackley Hospital (also known as Mercy Health Partners, Hackley Campus) is an acute care facility with some 180 beds that serves patients living in Muskegon, opposite the thumb on Michigan's shoreline. The hospital, founded in 1904, offers such services as behavioral health care, a sleep analysis lab, a bariatric treatment center, a cancer center, Alzheimer's disease and stroke care, emergency medicine, and rehabilitation therapies. Hackley Hospital's former parent, Hackley Health, was acquired by Trinity Health in 2008 and was merged into Mercy Health Partners, a Trinity division that operates three additional Michigan hospitals.
