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.

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.

Eva (she/her/hers) is a leader, innovator and adventuresome expert in the field of sustainable tourism. Her experience and broad range of skills span across 20+ years and include both undergraduate and graduate degrees in hospitality, tourism and travel; all facets of domestic and international operations and logistics for various global educational tours and programs, from program development and risk management protocols to sourcing new destinations and strategic partnerships across Europe.

Having grown up in Stockholm, Sweden, Eva’s international explorations began early on: At nineteen years of age, on a quest for adventurous experiences, she waved her native Sweden goodbye from the deck of a 44’ sailboat, and never looked back. What ensued was, and continues to be, a life full of rich learning experiences that have included sailing across the Atlantic Ocean, volunteering at the first ever conference on ecotourism, crossing the Andes on horseback and living in the West Indies, Portugal and, since 1994, the U.S.A. Eva is based north of Boston, MA and loves anything and everything 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.
