Family Promise's mission is to help homeless and low-income families achieve sustainable independence through a community-based response. Poverty is a complex situation that often tends not to have a simple solution. It requires and integrated approach that reaches beyond immediate needs. Graystone helps meet this integrated approach as it partners with Family Promise to help coordinate efforts that bring communities together to help homeless families regain their housing, their independence, and their dignity.
