    United Memorial Medical Center History

    United Memorial Medical Center was formed by the merger of Genesee Memorial and St. Jerome Hospitals on January 1, 2000. In 1902, a group of community minded women formed the original Batavia Hospital. In 1917, the Sisters of Mercy opened St. Jerome Hospital after Batavia resident Rose Jerome willed her family home on Bank Street to the order for use as a school or hospital.
