The present company was formed on January 28, 1999 by the merger of
Houston's
Sisters of Charity Health Care System and
San Antonio's Incarnate Word Health System; however its history extends back to 1866, with the founding of
St. Mary's Hospital in
Galveston, Texas, by the Sisters of Charity
religious institute. Another significant merger came in 2016 when CHRISTUS merged with
Trinity Mother Frances Hospitals and Clinics (itself the product of a merger of two Catholic-based systems), giving it a major presence in East Texas. CHRISTUS Health services can be found in 60 cities in
Texas,
Arkansas,
Louisiana, and
New Mexico in the U.S.; also, in the
Pontificia Universidad Católica de Chile Health Network in
Santiago, Chile, and
Chihuahua,
Coahuila,
Nuevo León, Puebla, San Luis Potosí, and Tamaulipas in
Mexico. The system comprises almost 350 services and facilities, including more than 60 hospitals and long-term care facilities, 175 clinics and outpatient centers and dozens of other health ministries and ventures. Its corporate headquarters are in
Irving, Texas. It employs approximately 30,000 people and has more than 9,500 physicians. == References ==
