AdventHealth (formerly Adventist Health System) is a faith-based, non-profit health care system headquartered in Altamonte Springs, Florida, that operates facilities within nine states across the United States. The Adventist Health System was rebranded AdventHealth on January 2, 2019. It is the largest not-for-profit Protestant health care provider and one of the largest non-profit health systems in the nation.   It has 45 hospital campuses, more than 8,200 licensed beds in nine states, and serves more than five million patients annually. 
At the behest of Ellen G. White, the Seventh-day Adventist Church first established the Western Health Reform Institute in Battle Creek, Michigan, in 1866, to care for the sick as well as to disseminate health instruction.  Over the years, other Adventist sanitariums were established around the country. These sanitariums evolved into hospitals, forming the core of Adventists' medical network.
In 1973, the Church decided to centralize the management of its health care institutions on a regional basis and, in so doing, formed AdventHealth to support and strengthen Seventh-day Adventist health care organizations in the Southern and Southwestern regions of the United States. 
Ten years later, the regional operations formed a national organization, Adventist Health System. 
AdventHealth currently operates 45 hospitals with more than 8,200 licensed beds in nine states, 15 skilled nursing facilities and 36 urgent care locations; serves more than five million patients annually in inpatient, outpatient and emergency room visits; and employs more than 80,000 people. 
AdventHealth is "extending the healing ministry of Christ". They adhere to a faith-based model called CREATION Health. 
AdventHealth's main facility, AdventHealth Orlando, formerly Florida Hospital, was founded in 1908 and is the largest hospital in the United States, according to Becker's Hospital Review.  It was ranked the No. 1 hospital in the state of Florida by U.S. News & World Report.
