When the Dominican Sisters of the Congregation of St. Catherine of Siena founded Saint Alphonsus Medical Center in Ontario in 1911, they dedicated themselves to providing health care to all people in a compassionate, understanding and dignified manner.

Today, the same philosophy guides our actions. The Saint Alphonsus Medical Center - Ontario team strives to provide high quality care which meets patients' medical needs while providing emotional and spiritual support to patients and their families.

We serve adults in all walks of life - from age 18 to seniors - and provide birthing services and newborn care as well as care for pediatric patients. Saint Alphonsus Medical Center - Ontario offers a full continuum of health care - from acute care and outpatient services to rehabilitation and home care.
