Katrina Winograd
Rock Bottom Ranch Educator

Kitty is a Colorado native who grew up in Littleton, Colorado. She attended the University of Colorado at Boulder where she majored in English Literature and minored in Ecology and Evolutionary Biology. Her senior year was spent crafting an honors thesis tying her passion for literature and her love for and curiosity of the natural world together at last. The thesis explored the often tense relationship that exists between the natural and man-made worlds, as represented in Cormac McCarthy’s The Road, Barbara Kingsolver’s The Poisonwood Bible, and Linda Hogan’s Solar Storms. Though varied in theme and symbol, the thesis ultimately spoke of the need for environmental literature as an effective tool for introducing environmental issues to non-scientific communities in lyrical and powerful ways. After graduation, Kitty spent a summer interning at Thorne Nature Experience in Boulder, CO where she got her feet wet (at times literally!) teaching wetland ecology and environmental education to fourth grade field trip classes. Kitty joined the ACES staff in the summer of 2014 as a Summer Naturalist. She returned again in the summer of 2015 as a Summer Educator at Hallam Lake, and is back representing ACES in her split time at Basalt Elementary School and Rock Bottom Ranch. In her free time, she enjoys exploring the biggest backyard she has ever had – The Roaring Fork Valley. Recently though, her explorations have turned to the page once again, where she spends her nights working on her master’s degree in Public Administration and Environmental Management through CU Denver. Most of all, Kitty is excited and grateful for the continued opportunity to get to know all of ACES and the many programs and sites it has to offer, as well as her fortune in having a full, varied life.
