Many of the social determinants that shape health also are tied to poverty, such as employment, education, housing, and the built environment. The community development and health sectors have worked for decades to address these challenges—but historically, these two sectors have worked in siloes, even when serving the same people and places. PHI builds successful collaboration between public health and community development practitioners, advancing community health and health equity through shared goals, strategies, and resources. We develop and support upstream interventions that address social, economic and community conditions—ensuring that community investments are smarter, more strategic, more aligned, and more effective. PHI and our programs curate relevant best practices, and advance field knowledge of social impact investing, sustainable financing, and other emerging topics.
