We believe that the path to sustainable positive change for the health of our communities lies in multi-sector, collaborative, interdisciplinary efforts that address the root causes of public health inequities rather than treating the symptoms. TRIC’s mission of supporting cooperative planning across municipalities, and doing so within a framework that considers how decisions made in one community will affect the neighboring towns and cities, is a strong example of the kind of interdisciplinary collaboration we have pledged to expand in the Blue Hills.
