Ethan Billingsley is the program lead and an instructor for the Graduate Certificate in Adventure Tourism. Ethan is an alumnus of Warner College – earning his B.S. in Natural Resource Recreation and Tourism and his M.S. in Human Dimensions of Natural Resources. He served as director of undergraduate programs in the college from 2008-2018.

Prior to joining CSU, Ethan worked as both an educator and guide in various capacities. He has led single and multi-day whitewater rafting trips for the last 20 years and is currently a certified raft and stand up paddleboard guide in the state of Colorado. He has climbed all 58 of the Colorado’s 14,000ft mountains and led many CSU groups to those summits as well. He also spent 7 years working in summer camps and outdoor education centers where he gained considerable experience in group dynamics and leadership. Additional experience has included work as a rock-climbing instructor, backpacking guide, and sea-kayaking naturalist. Ethan loves learning about the ecology of an area as much as he likes adventuring in it. In his free time, Ethan loves spending as much time as he can with his wife and two sons in the outdoors.

Mark Gasta, Ed.D., Founder – Adventures in Leading

My research and teaching passion focuses on the relationship between adventure, self-awareness, and personal purpose.  Through travel and adventure, individuals are exposed to something bigger than oneself, often resulting in introspection, self-awareness, and expanded worldview.  This personal clarity can serve as a calling for individuals to define and live a life in alignment with their personal values.  It is my hope that this greater sense of purpose will result in individuals who build lives and organizations that do both well and good.  Individuals that ultimately build and lead sustainable organizations that create profit for shareholders while protecting the environment and improving the lives of those with whom they interact.
