The idea for Chulengo has been a long time in the making, taking its ethos from generations of adventurers-turned-environmentalists.  As our mentor Kris Tompkins puts it, "we defend what we love, and we love what we know."  Every day of bushwacking through remote valleys and scrambling unnamed peaks reinforces the special power of wild landscapes to challenge, inspire, and transform. 

Chulengo benefits from the wisdom and support of many, including those below.


NADINE LEHNER (Co-founder)

After years working in conservation while exploring wild places, Nadine dove into Chulengo to build connections between people and place that inspire lasting change. After graduating from Harvard College, where she studied History & Literature with an environmental focus, she headed south to work with Doug and Kris Tompkins (founders of The North Face, Esprit and Patagonia, Inc).  As Executive Director of Conservacion Patagonica, she focused on the establishment of the future Patagonia National Park, the 700,000-acre flagship national park that is home to most of Chulengo's expeditions. After five years with Conservacion Patagonica, she pursued a joint MBA - MS in Environment and Resources at Stanford University.  She's a NOLS instructor and has led wilderness backpacking and river expeditions for over a decade. She now spends most of her time in one of her favorite places on earth, Patagonia National Park, leading expeditions with Chulengo. 


Ben works as a guide and educator in the Aysén region of Chile, with a particular focus on student groups and environmental conservation. During the 2015 season, Ben directed Conservación Patagónica's field volunteer and education program, spending nearly five months living in a tent in the backcountry of the future Patagonia National Park. He has also worked with teams of local guides to manage expeditions onto the Northern Patagonian Ice Field, one of Patagonia's most remote areas. Ben studied Latin American History as a Harvard undergraduate, which included stints in Argentina and Brazil, and completed a degree in philosophy at Oxford University. A long-distance cyclist, he has pedaled across North America, South America, and Europe. When he isn't leading expeditions for Chulengo, Ben works on translation projects for the Coyhaique-based publishing house Ñire Negro and collects stories that relate to the history of Aysén. 


Rock-star conservationist and businesswoman Kris is a crucial mentor to Chulengo.  After co-founding Patagonia, Inc with Yvon and Malinda Chouinard, Kris served as the company's first CEO for two decades before retiring to move to Chile and focus on conservation with her late husband Doug Tompkins. In 2000, she founded Conservación Patagónica to create national parks in Chile and Argentina that save and restore wildlands and wildlife, inspire care for nature, and generate healthy economic alternatives for communities.  With Doug, she has secured protection for more land than any other individuals in history - over 2.1 million acres - and enabled the establishment of numerous national parks. 


Environmental education and behavior guru Nicole guides the vision and approach of Chulengo. As an associate professor with a joint appointment in the Graduate School of Education and the Woods Institute for the Environment at Stanford University, Nicole focuses on environmental behavior and place-based connections. Nicole has current studies on the use of education, communications, and other social strategies in informal and community-based settings, including nature-based tourism programs, to engage individuals and communities in deliberate dialogue, environmental decision-making, and informed conservation behavior. She also researches the effectiveness of a range of environmental education and social science endeavors in achieving measurable and meaningful conservation results.


Rene Sandoval

Rene coordinates transportation and logistics for Chulengo, bringing decades of experience in the Aysen Region to this role. Originally from Rio Bueno, Chile, he has lived in Coyhaique for many decades. As an officer in the Chilean military, Rene gained an appreciation for detail-oriented coordination and logistics. Through his company, Servicios Integrales, he has helped hundreds of travelers to the Aysen Region organize safe and efficient transportation. A proud Aysenino, he enjoys sharing his knowledge of the region with travelers and students.

Paula Bozzolo

Born and raised in Santiago de Chile, Paula first visited Patagonia in 1986 as a leader for Operations Raleigh Chile. One of her first projects occurred in the area that is now Patagonia Park. Later, she worked as a trekking guide for the Explora Hotel in Torres del Paine National Park. In 1997, with her partner Rodrigo Noriega, she joined Doug and Kris Tompkins' team, creating Pumalin Park. They lived in the remote heart of the park (for the first two years, in a cabin with no electricity or running water), got married there, and raised two children. Paula ran the Information Center at Caleta Gonzalo, touristic operations of the bee project at Pillan Farm, and production of organic jams. In total, Paula and her family lived in Pumalin Park for twelve years. She says: "I am very lucky and proud to have helped in the creation of Pumalin Park and Patagonia Park, and to have shared this experience with Doug and Kris Tompkins." Now Paula is becoming a Forest School Leader for early learners. For Paula, "being outdoors is going back to basics. It is the opportunity to reconnect with myself and nature, to find my own rhythm."
