Ascension Health Alliance, St. Louis, has signed a memo of understanding to acquire Tulsa, Okla.-based Marian Health System and its three regional divisions, according to a news release (DOC).
The deal between the two Roman Catholic providers could be finalized by the end of the first quarter of 2013, officials said. Financial terms weren't disclosed. Marian includes 36 affiliated hospitals and more than 150 clinics in Wisconsin, Minnesota, Oklahoma and Kansas. The system is comprised of Ministry Health Care in Milwaukee, St. John Health System in Tulsa, and Via Christi Health in Wichita, Kan. The latter is already affiliated with Ascension Health.
