Our Chicago site has become one of the strongest hubs for Detailing for MCAS, bringing the community together through weekly car-detailing fundraisers and awareness events. Volunteers in Chicago have played a key role in expanding our mission by raising thousands of dollars to support research, advocacy, and patient support for Mast Cell Activation Syndrome (MCAS). Beyond fundraising, the site fosters community engagement and provides a platform for storytelling, allowing patients and families to share their journeys. Chicago continues to serve as a model for how local action can drive meaningful global impact.
