MHRL: A Legacy of Local Support
The Mental Health Resource League is an all-volunteer nonprofit that has been serving McHenry County since 1967. We raise funds, award grants, and make sure local mental health agencies have resources to serve our community.
A Shared Mission for Mental Health
Collaboration is at the heart of our work. By awarding grants to these essential local organizations, we are working together to build a stronger, more resilient support network for our community.
