Through a network of county offices, the University of Missouri solves problems and engages with communities across all 114 counties and the City of St. Louis.

MU faculty, staff and elected council members, who live in your community, work with you to identify local interests and issues and then offer relevant programming and resources to meet the unique needs of you and your community.

Our job is to partner with communities to find solutions with credible, science-based information that will help you:

  • Grow safe and healthy food
  • Build and grow profitable businesses
  • Improve your health and relationships
  • Increase agricultural production
  • Update professional training in business, health and safety
