Rachael DeGraffenried, Administrative Assistant, brings years of non-profit and administrative experience to the Aspen Science Center. She obtained a BS degree in Business Management with minors in International Studies and Entrepreneurship from the University of Wyoming. After college, she fed her desire to help others and travel by doing humanitarian work with local nonprofits in 11 different countries in Southeast Asia, Southern African and Eastern Europe. Back in her home state of Colorado, her administrative and event-planning skills were expanded through her work with a fitness-based elementary school fundraising organization. Rachael met and married her husband in Colorado, and then they promptly moved to Seattle, Washington, where she worked as the Volunteer Coordinator for Outdoors for All. In this role she recruited and managed over 700 volunteers and aided with development efforts such as the annual auction, all in support of the organization’s outdoor recreation programs for people with disabilities. Finally, she rounded out her experience in education, teaching English, Social Studies and French to middle and high school students. She eagerly brings her administrative, development, and teaching experience to the world of science education and discovery at the ASC. When she isn’t making lists or geeking out over Excel spreadsheets for the ASC, she enjoys re-reading Jane Austen novels, baking cakes from recipes off the Great British Baking Show, and swimming at the local rec center in Glenwood Springs where she now resides.
