Let's Talk About Mental Health

Community Conversations on Supporting Action for Mental Health in Longmont: What’s next? 

Supporting Action for Mental Health (SAM) invites you to attend one of four community conversations to share your ideas regarding SAM’s role in addressing mental health throughout the city of Longmont. During each meeting, we will review the history of SAM, discuss its current state, and — with your help — identify next steps for the future.

SAM is a network of local government, groups, organizations, and residents working together to support individuals experiencing mental health issues in Longmont. For more information, including additional community conversation dates and locations, visit or download a flyer.
