It is with profound sadness and heavy hearts that we share the news that Matt Siemer, Executive Director of Mobile Care Chicago, passed away over the weekend as a result of a tragic car accident.
Matt was more than a leader, he was the heart of Mobile Care Chicago. His 13 years of vision, compassion, and unwavering commitment to equity in health care shaped this organization and touched countless lives across Chicago and beyond. Through his transformative leadership, MCC expanded its reach, strengthened its impact, and remained steadfast in its mission to bring free, comprehensive, specialty care directly to communities who need it most.
Those of us who had the privilege of working alongside Matt knew him as a thoughtful, principled, and deeply caring person. He was the ultimate problem-solver, endlessly curious, and kept a good sense of humor, even in difficult times. He believed fiercely in our patients, our staff, and the power of meeting people where they are. His legacy lives on in every family we serve.
We are deeply grateful for the partnership and trust you shared with Matt and with Mobile Care Chicago. Your support makes possible the work he cared so deeply about, and it is because of his leadership, and partners like you, that MCC continues to reach communities where care is often out of reach.
Mobile Care Chicago’s Board of Directors and leadership team are working closely together and programs and services will continue. Our mission remains unchanged, and we are committed to honoring Matt’s legacy by carrying this work forward with the same dedication and purpose he embodied.
Matt’s wife — also an accomplished changemaker in the healthcare space— was severely injured in the accident. A GoFundMe has been created to support her at this time:
