Welcome to Yellowstone County's Extension Office.

The Yellowstone County Extension Service is an off-campus arm of the Montana State University. Our purpose is to provide unbiased, research-based information, educational resources and outreach programs through the Land Grant University System. Extension Agents help people interpret the information and encourage the application of it to the solution of problems. This unbiased base of knowledge gives people the means to meet ever changing needs and make sound decisions that impact their lives and their communities.
