Turning great ideas into healthier communities


Health Education & Promotion

Health outcomes are tied to individual behavior, and are also shaped by our surrounding environments. We offer health promotion expertise including agriculture and nutrition, active transportation, climate change, obesity prevention, telehealth and health information technology, sexual and reproductive health, and alcohol, tobacco, and substance use. A leader in the movement to build healthier communities, PHI focuses on community empowerment and community-based solutions, with a specific emphasis on underserved populations. For two decades, PHI has supported Supplemental Nutrition Assistance Program Education Program (SNAP-Ed) education, training and implementation nationwide, which create award-winning health promotion campaigns and have made measurable improvements in healthier eating.

Here's How We're Making a Difference

Bolstering What Works to Stem the Opioid Crisis

In 2019, PHI's California Bridge launched an accelerator training program at 52 hospitals and ERs across the state, supporting healthcare providers offering 24/7 access to medication for addiction treatment (MAT). Since the program’s inception in April 2019, these sites have collectively served just under 5,000 people, 1856 of whom have been successfully connected with an ongoing source of outpatient substance use treatment. 

PHI’s California Opioid Safety Network (COSN) is the largest opioid safety network in the country, serving 85% of California's 30 million people. Now, 90% of COSN coalitions are distributing naloxone and 91% are increasing access to MAT.

And in June, PHI hosted U.S. Surgeon General Jerome Adams at its first-ever National Opioid Leadership Summit, bringing together public health, health care and criminal justice experts to share the best practices and develop cross-sector solutions. 


Changing Health Behaviors

The Network’s work lives on as PHI’s Center for Wellness and Nutrition.



HelpingĀ SNAP-Ed Eligible Moms & Families Eat MoreĀ Healthily

Children smiling and eating watermelon on a summer dayA 2019 study from PHI's Center for Wellness and Nutrition (CWN) found that SNAP-Ed eligible families in California added an additional one-third of a cup of fruits and vegetables to their meals daily, and increased water intake by a cup a day between 2015 and 2017 (teens increased by two cups a day)—which means these families are eating as healthily as Americans of all income levels. See the study.

In 2019, CWN also provided SNAP-Education and other nutrition-related services in 25 states nationwide, collaborated with 230 partner organizations including social service agencies, health departments, health care agencies and universities. CWN trainings supported over 1,100 individuals on wellness and nutrition topics including community and youth engagement, health equity, systems change, local school wellness policies, healthy food system interventions and evaluation—and worked with 20 food retailers like grocery stores and farmers markets to improve access to healthy fruits and vegetables. CWN also supported capacity-building and leadership efforts in 61 community-based organizations that directly serve low resourced community and communities of color, to increase or improve wellness services and equity.
