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
  • Engage youth as valued, contributing citizens

MU Extension County Council of the Year Finalist Banner

County Council of the Year

The St. Charles County Extension Council was named a finalist for the MU Extension County Council of the Year for 2023.

The award recognizes the central role councils have in:

  • identifying local opportunities and challenges around agriculture, economic opportunity, education and health
  • engaging local communities and representative voices
  • connecting MU Extension with local partners
  • supporting initiatives that create measurable, lasting impact.

The County Council of the Year Award is another way to elevate council members’ voices as powerful advocates for MU Extension as we serve Missouri and deliver Mizzou.
