Terri L. Geissinger

The History of Wyoming is Alive, Wild and Well.

I am a proud descendant of Wyoming Pioneers. My ancestors were tough, courageous and endured incredible hardships and great success. They loved and appreciated this hard, beautiful land as it was excellent ground for their ‘woolies’ but it was never easy. The challenges of surviving the hazards of a wild frontier weaved thrilling tales. I grew up listening intently to these rugged family stories which ignited my passion and lifework for preserving history. I believe that Wyoming history continues to be vibrant and compelling because this land remains homeplace for many Native and Pioneer families who value their legacy stories. Those family sagas are embedded in our communities and the relationship between our roots and ranches remain. Wyoming is wild by nature and by preserving the stories we keep the history alive and well. 

Terri Geissinger is a professional non-profit administrator with over 25 years of experience in preserving history. Her wide skill-set includes historic preservation and interpretation, fundraising, membership, retail sales and special events. Her specialty is collaboration and creating sustainable programs and goals. She has deep passion for history and as a Wyoming Pioneer descendant, she looks forward to preserving our past for future generations.

Serving first term, eligible for re-election in 2026.
