Born and raised in southwest Montana, Kari spent plenty of time in the Jackson area as a child. She began ski racing at the age of five, and attributes her first round of frostbite to a ski race hold during the Snow King downhill. After graduating from Mead High School in Spokane, WA, she headed to the Seattle area for college. Kari graduated from Pacific Lutheran University in Tacoma, WA with a BA in Communications and Sports Administration and minors in Coaching and Sports Psychology. Unbeknownst to her, a work-study position in her alma mater’s development department proved to be the launch point for her career.

She spent the last 25 years working in the nonprofit sector focused on health, education and athletics in Tacoma, Denver, Vail and Ellensburg, WA – a Western girl at heart. She’s thrilled to be back “home” and to work with the TVRC leadership team to create an inspired and sustainable development department for the Foundation.
