County Services

There is an extension office in all 99 counties of Iowa, which bring Iowa State University research-based educational experiences to Iowans. In turn, they communicate the needs of Iowans back to the university to help shape research and educational experiences. Extension offices are represented by 900 elected extension council members who promote and advance the reputation, interest and resources of Iowa State University.
