Barbara "Barb" Oldershaw

Barb is a seasoned project management professional with a passion for facilitating authentic community engagement. She is inspired by the willingness and determination with which Park County residents seek to resolve local challenges -- and looks forward to leveraging her strategic planning skills on behalf of the Park County Community Foundation. 

Barb moved to Montana from coastal California, where her non-profit experience spanned urban issues in the San Francisco Bay Area and rural concerns in Sonoma County.  She’d love to tell you more about her work in adult education, inter-faith coalitions, sustainable agriculture, energy efficient wineries, and B Corp certification! Barb holds a BA in Community Development from the University of California-Berkeley and an MA in Architecture & Urban Planning from the University of California-Los Angeles. She is a proud graduate of MSU-Park County Extension’s Leadership 49 program and in 2019 was elected to the Board of Directors for the Montana Renewable Energy Association (MREA). Barb raised up her daughter in her own hometown of Berkeley, California, and in the process learned a lot about multi-generational connections and sustaining long-term relationships.
