OSF HealthCare announced today that Tom Hammerton, president of the OSF HealthCare Foundation and chief development officer for OSF HealthCare, will retire from his role effective April 3, 2026.
Hammerton has dedicated 17 years of service to OSF HealthCare, including the past 12 years as president of the OSF HealthCare Foundation. During his tenure, he has led multiple major capital campaigns, including those supporting OSF Children’s Hospital of Illinois, the OSF Richard L. Owens Hospice Home, Jump Trading Simulation & Education Center, Almost Home Kids and the OSF Cancer Institute.
Hammerton has been instrumental in shaping and advancing OSF’s philanthropic strategy, strengthening donor engagement, and fostering a culture of generosity that supports the Mission of OSF HealthCare.
In addition to his leadership in philanthropy, he has played a pivotal role in the development and success of the OSF Cancer Institute, helping to ensure transformative care for patients and families.
Through strong partnerships, including with David Vaughn Investments and OSF’s generous donor community, Foundation assets have grown from approximately $30 million to nearly $400 million during his tenure.
OSF HealthCare will begin a national search immediately to identify the next president of the OSF HealthCare Foundation and chief development officer. This recruitment is a strategic priority for the organization, with a focus on selecting a leader who will ensure continuity and support the long-term needs of the Foundation and OSF HealthCare.
Through the remainder of his tenure, Hammerton will continue in his role with a focus on transitioning key donor relationships and supporting an orderly leadership transition.
An announcement will be made once a successor has been selected.
