The National Network of Wellness Councils (NNWC) is a collaboration of local coalitions that work to improve population health and economic development. The NNWC provides tools to assess community health, identify appropriate interventions, and evaluate return on investment. Chronic disease costs communities greatly, and the five components of local coalitions - which include assessing health, planning initiatives, enacting programs, and reviewing results - can help address preventable health issues. Local leadership engagement and data-driven strategies are key. The NNWC supports communities in establishing effective wellness initiatives.
