La Crosse County, WI has been working since 2017 to build a Resilient and Trauma-Informed Community and the primary target of this effort has been aiming at the "process of how community partners work together to achieve systems-level change". Early on we acknowledged that large scale change does take time and committed to following a couple key models to guide our change effort.
Interestingly, our effort is not funded by a grant but instead through our intentional commitment and effort to achieve Foundational goals that set up key conditions for collaborative, large scale change to happen. Early strategy involved purposeful effort to promote community partner buy-in and collaborative ownership in the effort. While we do not have a grant driving the effort, we do have a couple key organizations who dedicated staff to support the larger collaborative community effort.
One of our goals from the beginning was to capture our process into a framework for other communities to use, follow and partner with us on.
