Public Policy Development

Changing policies and practices at a school or preschool, in a local business or workplace, or in a neighborhood, state, and country can create palpable and lasting change. PHI produces forward-thinking research, develops proposals, initiates evaluations and builds buy-in in order to inform and shape some of the most complex policy challenges facing the nation today, including: agriculture and nutrition, marijuana, transportation planning, climate change, economic development, nutrition, healthy communities,  health information technology, and alcohol, tobacco and substance use. PHI's approach is centered on the importance of evidence and data, boosting community power and voices, creation of political will, and crafting policies that yield just and equitable solutions.
