David Kallenbach, Executive Director

David first learned about the Absaroka-Beartooth Wilderness 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 in its alpine backpacking courses–but also for Montana’s quiet living and wide open space! He became the Montana Program Director for Outward Bound in Red Lodge, overseeing all programs in the field and promoting Outward Bound’s commitment to service–i.e. doing trail and restoration projects benefitting the wilderness trail system.

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

David grew up in Colorado and began hiking, backpacking and mountain climbing at an early age. Taking on this role as the Executive Director of the ABWF stems from a lifelong passion for adventurous activities in wilderness places while absorbing all he could learn from the natural world. His commitment to wilderness comes from a desire to see our wild lands remain un-impacted, their beauty unmarred, so that everyone has a chance to enjoy wild country in its natural state. He enjoys hiking and backpacking, mountain biking, snowboarding, XC skiing and snowshoeing, but also loves walking his dog, shooting photographs, or reading at home in Red Lodge, Montana.

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!
