PSE stands for changes in policies... systems... and environments! Here at Health and Human Sciences, our goal is to make healthy choices easier and more accessible. That’s what PSE is all about! Our nutrition and health education specialists work in every county of the state to help communities identify ways to support being healthy. Residents design strategies around local needs... assets... and interests! Learn more. Do more with MU Extension. Contact your local extension center for more info: extension.missouri.edu/counties
