Ascension Health formed Ascension in 2012 to further its Mission of serving all persons especially those living in poverty and who are struggling the most, and to deliver compassionate, personalized care and lead healthcare transformation in the United States. Restructured as Ascension, we are positioned to meet the evolving needs of the people and communities we serve in the rapidly changing healthcare environment. Today, we continue an 800-year legacy and promise set forth by our original sponsor organizations to provide faith-based healthcare to those in need. Learn more.
