Jane Allen
Jane has always felt a deep connection to the natural world around her. This love of nature led her to pursue a bachelor’s degree in Environmental Studies from University of Northern Colorado, followed by a master’s degree in the Climate Change and Society program at North Carolina State University. She has seen the impacts of a changing climate from coast to coast and has made it her mission to foster more sustainable and equitable communities through her work. After college, Jane moved to the Columbia River Gorge in Oregon to improve the resilience of local rural communities and to assist in developing a COVID-19 recovery plan for economic districts across the state. She is excited to return to Colorado to support the trailblazing effort of the Regenerative Recovery Coalition. In her free time you will most likely find her exploring the outdoors with her husky in tow, listening to live music or hanging out at a local brewery.
