HSHS now has 15 hospitals in Illinois and Wisconsin.

In the 1970s, Sr. Kosior and other congregational leaders developed a plan for bringing together the 12 U.S. hospitals founded by Hospital Sisters. They created a structure that would allow for lay management while also enabling the sisters continued involvement in sponsorship and governance. The resulting organization, HSHS, was incorporated Dec. 26, 1978.
Sr. Jomary Trstensky, OSF, said Sr. Kosior had an "unwavering belief that the future of Catholic health care would be built on strong systems and lay leaders. With no blueprint she established Hospital Sisters Health System and entrusted others to give life to her vision." Sr. Trstensky is chair of Hospital Sisters Ministries, the public juridic person of HSHS. She was HSHS president from 1989 to 2006.
Sr. Kosior had said of her ascension from dietitian to health system president: "I was open to the Holy Spirit and waited to see where the Lord was calling me."
