VOICES Voices Icon Ideas and Insight From Explorers


Gregg Treinish founded Adventurers and Scientists for Conservation in 2011, mobilizing outdoor enthusiasts in collaborative efforts to protect our natural world. Today, the Bozeman, Montana-based organization works with volunteers to collect and present scientific data, catalyzing global conservation initiatives.

National Geographic named Gregg Adventurer of the Year in 2008, when he and a friend completed a 7,800-mile trek along the spine of the Andes Mountain Range. In 2013, he became a National Geographic Emerging Explorer for his work with ASC. Gregg has a biology degree from Montana State University, a sociology degree from CU-Boulder, and has led expeditions to six continents.

Here, Gregg, his team and volunteers share stories from ASC’s work.
