We are deeply saddened to share the passing of Matt Siemer, President of the Chicago Asthma Consortium Board of Directors.
For more than a decade, Matt was a visionary leader, advocate, and mentor who brought compassion, structure, and a client-centered public health perspective to our work. Under his leadership, CAC expanded its impact, strengthened its resources, and supported hundreds of individuals living with asthma across Chicagoland.
Matt’s passion, authenticity, and commitment to our mission will be profoundly missed. We honor his legacy by continuing to advocate for people living with asthma, and we hold his family in our thoughts during this difficult time.
