David Kallenbach, Executive Director

David began his association with the Absaroka-Beartooth Wilderness back in 1996, seeking a change from his job as a high school science teacher in suburban Denver. He came to Montana to work for the Voyageur Outward Bound School that utilized the A-B Wilderness for its alpine backpacking courses–and also for Montana’s quiet living and open space! He became the Montana Program Director for Outward Bound in Red Lodge, overseeing programs in the field and promoting Outward Bound’s participation in trails and restoration projects on behalf of the wilderness.

At other times in his career he has worked as a Ranger/Naturalist for the National Park Service in far-flung places such as Denali, Alaska, and Death Valley, California—always inspired by life in beautiful places.

Growing up in Colorado, David began hiking, backpacking and mountain climbing at an early age. Becoming the Executive Director of the ABWF stems from a lifelong passion for wilderness activities and learning about the natural world, but also comes from a desire to see our wild lands remain un-impacted, their beauty unmarred, so that everyone has a chance to enjoy wilderness in its natural state. He enjoys hiking and backpacking, mountain biking, skiing and snowshoeing through Montana’s seasons, but will also be found walking his dog, taking photographs or reading from his home in Red Lodge.

Heather Briggs, Program Director

Heather fell in love with the outdoors as a child, chasing fireflies in the Smokies and watching osprey from the Lockwood Folly river in North Carolina. When she was 19, she did the California Conservation Corps/Americorps Backcountry Trails Program in the Yosemite Wilderness. That summer she fell in love with trail work, the Sierra Nevada, and high alpine lakes. She has since worked trails in the front and backcountry, led a Youth Conservation Corps crew, volunteered as a wilderness ranger, and worked on a roving restoration crew. While most of her experience has been in Yosemite, she spent a summer in Flagstaff where she learned wet masonry at Wupatki National Monument. Heather is nearly done with her B.S. in Environmental Management and is excited for the opportunity to work with the ABWF!
