Who We Are

Brandon Chappo is the Co-Founder and Director of Public Policy at Change the Air Foundation, where he leads national efforts to confront the growing public health crisis of poor indoor air quality. Working alongside military families, community advocates, and lawmakers across the country, he helps drive meaningful policy reform to ensure safer indoor air quality in homes, stronger standards, consumer protections and real accountability.

Grounded from his own long and difficult battle with mold exposure in a water-damaged home, Brandon’s work is rooted in lived experience. What began as a personal health fight has evolved into a mission to make sure no one else endures what he did, transforming hardship into advocacy and advocacy into legislative action.

Brandon has played a leading role in advancing landmark policies, including the federal Healthy at Home Act of 2023 and multiple state-level bill proposals alongside passionate advocates and volunteers. His efforts contributed to the unanimous passage of Illinois Senate Bill 1087 (The Mold Remediation Registration Act) in 2024. Most recently, he helped lead the push for a groundbreaking federal provision in the FY 2026 National Defense Authorization Act (NDAA), requiring all mold remediation in United States Department of Defense housing, facilities and all other real property to follow the industry standard of care, the ANSI/IICRC S520, a first-of-its-kind national safeguard for families in military housing.

Brandon was recently selected to serve as a Commissioner on the Global Commission for Healthy Indoor Air, collaborating with global leaders to drive healthier building practices and international indoor air quality reform.

Together, they owned and operated an HVAC company on the Northshore of Louisiana until AJ began suffering health complications that resulted in a diagnosis of epilepsy.
