John Peller, CEO of AIDS Foundation Chicago, announced he will step down at the end of 2026 after more than two decades with the organization, including 12 years as its leader. Peller described the decision as coming after “an incredible experience” leading one of Illinois’s largest HIV service organizations and a personal readiness for change. He emphasized that while the decision was difficult, leadership transitions are healthy for organizations and attributed the move partly to the accumulated strain of leading a nonprofit through the COVID-19 pandemic and ongoing political pressures.
Leadership Legacy and Expansion
Under Peller’s tenure, AIDS Foundation Chicago has experienced significant growth. The organization’s budget has expanded by 68%, staff has grown by more than 50%, and it now serves nearly 9,000 people annually through case management, housing, harm reduction, and behavioral health services. The organization’s housing portfolio grew from about 866 units in 2014 to more than 1,100 today, helping provide stable housing to more than 2,000 people living with HIV each year. Peller has prioritized addressing social determinants of health—barriers such as housing instability, lack of insurance, and limited access to dental care that prevent people from engaging in HIV treatment.
Challenges Ahead
The organization faces a challenging operating environment. Chicago saw a 12% increase in new HIV cases in 2024, a trend Peller called “especially concerning as public health infrastructure faces cuts.” He warned of a “very unstable funding environment,” noting that while federal HIV funding has remained level in recent years, future appropriations are uncertain. Potential cuts to Medicaid, which covers approximately 18,000 people living with HIV in Illinois, also present significant threats to health care access.
The board plans to launch a national search for Peller’s successor later in 2026, with Peller remaining through December to ensure continuity and transition planning. He emphasized that his commitment to HIV advocacy will continue, stating: “No matter what I do, my heart is always going to be with the work to end the HIV epidemic.”
