Crook County

The OSU/Crook County Extension Service, located in the city of Prineville, has provided research-based, informal educational programs to the citizens of Crook County since 1914. This is done through coordinating educational tours, conferences, short courses, workshops and demonstrations. We also provide brochures, publications, and research based information on a variety of subjects both in the office, over the phone, in the field, and on line.

Extension staff in Crook County along with regional Extension Staff and volunteers, offer programs and assistance in 4-H & Youth Development, Agriculture & Natural Resources, Family & Community Health, Forestry & Natural Resources, Livestock, Marine/Fisheries, Range & Natural Resources and Small Farms/Small Acreage.
