STEM at Chadwick immerses students in exciting and experiential learning that prepares them for success out in the real world.

Meet Our Instructors

Chadwick’s Outdoor Ed instructors are incredibly passionate people who have dedicated their lives to experiential environmental education. In addition to teaching survival skills, instructors act as emotional anchors for students as they navigate increasingly challenging endeavors out in the wilderness.

Outdoor courses present unique opportunities for students to experience powerful teaching moments that couldn’t possibly be mirrored at home or in the classroom. Using small group adventure as a vehicle for learning, Chadwick Outdoor Education instructors​ engage students in developing trust, critical thinking, community, independence, communication and an appreciation for nature.

As they advance through the grade courses, instructors thoughtfully encourage students to take physical and emotional risks while keeping actual risk to a minimum. As a direct result of these challenges, they return home having transformed their relationship to themselves, their environment and to each other.

Instructors follow a written syllabus for each course and adhere to a detailed set of risk management policies designed to keep students safe. All instructors have CPR and Wilderness First Responder certifications.

After graduating high school, he decided to pursue Outdoor Education at Prescott College in Arizona, a school known for its commitment to the environment, experiential education, and human development. Keo currently lives in Hayward, California, and enjoys spending his free time gardening, rock climbing, fishing, and surfing (not much has changed since childhood). He is thrilled to have the opportunity to work at a school like Chadwick and looks forward to helping the program and its students grow in the future.

Danner Bradshaw

Danner Bradshaw grew up in lower Alabama where he spent most of his childhood roaming the forests and beaches along the Gulf Coast. At the age of 15, he moved to the mountains of Vermont and attended the Putney School, which has many similarities to Chadwick. There he fell even more in love with the outdoors and began leading orientation trips for incoming students. After going to college to study fine art photography, Danner realized that his true passion was for outdoor experiences and in helping others discover the beauty of the natural world. As an extension of this passion, Danner became fascinated with birds and natural science, and ultimately ended up majoring in ornithology. He moved to Joshua Tree in 2005 to begin his career in outdoor education, working for many of the schools in the Los Angeles area, and in the summers he would travel to work avian research jobs at the Grand Teton National Park in Wyoming or Acadia National Park in Maine. In 2013, Danner began working at the Chadwick School and has worked nearly every Chadwick trip since then.

Jonas Cole

Having grown up in the backwoods of Vermont, Jonas Cole developed a love for the outdoors at a young age.

Between childhoods spent seeking alpine lakes and a few formative years at a nature awareness camp in West Virginia, she developed a passion for wild and beautiful places, outdoor adventure and conservation. After graduating from Harvard University in 2007 with a degree in Visual and Environmental Studies, Anna was burning to adventure so she set off on a "stint" of traveling and seasonal work. That stint turned into more than a decade of exploring and teaching in the great outdoors, including leading canoe expeditions on desert rivers, backpacking trips in the mountains, and snorkeling and kayaking around various islands. In 2019, she completed a master's degree in Community and Regional Planning at the University of Oregon, a wonderful program that allowed her to study such diverse topics as bicycle infrastructure, sustainable materials management and public lands leadership. In her free time, Anna continues to explore the great outdoors, travel and connect with friends and family.

Roddy McCalley

Roddy McCalley grew up in Palo Alto, way before Google. Family vacations were mostly spent backpacking — spring and fall in the Coast Ranges, and summer in the High Sierra.  After graduating from Yale University with a degree in biology, Roddy spent most of a decade working as an outdoor educator, with no fixed abode and all his worldly possession in a Toyota Corolla. It was during these years that he became hopelessly obsessed with rock climbing. In 2009 he settled in Joshua Tree, California, where he works as a rock climbing instructor during the fall-winter-spring season. Summers are time to leave the desert and go play in the mountains — recent summers have included trips to the mountains of Wyoming, Colorado, British Columbia, Washington, Idaho and of course (still best of all) California’s very own High Sierra. Roddy suspects that if every person found a passion such as climbing — something that makes you want to be strong and healthy and engage in positive ways with other people — we would have far fewer problems in the world, and far healthier people.
