Mission & Focus Areas
Founded in 1911, the Institute’s stated mandate is “the investigation of the cause of disease and the prevention and relief of human suffering” in Chicago, Cook County, and Illinois. The foundation recognizes social determinants of health—including intergenerational poverty, systemic racism, and zip code—as affecting quality of life and life expectancy.
For 2025–2028, its two stated priorities are Community Health Access, reducing barriers to health and creating pathways for underserved populations and communities, and Healthcare Workforce, expanding professional pathways for under-represented groups and supporting work environments that promote staff performance, safety, retention, satisfaction, and a robust healthcare sector.
The foundation’s 2025 grants included organizations whose own missions describe work such as delivering no-cost medical and preventive care to low-income children and families (Mobile Care Foundation), improving the health of individuals and communities served (Sinai Health System), and improving health through patient care, education, research, and community partnerships (Rush University Medical Center). The Greater Chicago Food Depository describes its mission as ending hunger and treats food as a basic human right.
Grantmaking
The foundation reports two grantmaking cycles each year, in summer and winter, and says it currently operates by invitation only. It prioritizes pilots and other initiatives that seed new approaches to health and healthcare in the Chicagoland region; partnerships that convene organizations are of particular interest. It also states a commitment to full-cost funding and considers collaboration-related expenses appropriate partial uses of awards.
In filing year 2025, the foundation reported 16 grants totaling $2,320,878. Grant amounts ranged from $10,000 to $350,878, with a median of $100,000. Among the largest awards were $350,878 to the University of Illinois at Chicago, $300,000 to the Greater Chicago Food Depository, $250,000 to Sinai Health System, and $225,000 each to Mobile Care Foundation and Rush University Medical Center. These grants were reported for program support.
