David Howk
Hometown: San Antonio, Texas
Favorite animal in the Greater Yellowstone Ecosystem: Moose
Born and raised in the Texas hill country, David grew up hearing stories from his parents of the majesty of Yellowstone and Grand Teton National Parks. While earning his degree in Biomedical Sciences from Texas A&M University, David assisted in the care of captive elk, lynx, and white-tailed deer, some of the animals found in the Greater Yellowstone Ecosystem. After realizing that he couldn’t safely own a pet moose, he decided to move to Jackson so he could see them daily. Since arriving, he has thoroughly enjoyed sharing his passion for the parks by creating memorable experiences for his guests while also inspiring love for our beautiful planet and its creatures. The fact that Jackson Hole has 3 more seasons than Texas is an added bonus. When not guiding, David enjoys hiking with his dog, skiing and snowboarding, reading, and gazing up at the Teton range.

Favorite animal in the Greater Yellowstone Ecosystem: Osprey
Helen grew up exploring northern Wisconsin’s forests, lakes, rivers and bogs. She attended the University of Wisconsin-Madison where she earned dual degrees in Conservation Biology and Environmental Studies. There she had the opportunity to study marine and terrestrial tropical ecology in Ecuador, and she focused her studies on alpine plants in high Andean grasslands called páramos. Throughout her time in school and after graduating, Helen led 9 to 45-day canoeing, sea kayaking, and backpacking expeditions focused on leadership development amongst groups of young women. These trips led her from the Great Lakes Region to the tundras of the Canadian subarctic in Nunavut and Northwest Territories, where she developed a love of hardy plants and animals thriving in cold, dry places. In 2019, Helen moved to Jackson and began working for Teton Science Schools as a Field Instructor, marrying her passions for science and the natural world with her experiences leading in outdoor education. With this unique landscape and its wild inhabitants in the foreground, she has since had the opportunity to connect with hundreds of visitors in this spectacular ecosystem. When not out inspecting nooks and crannies of high alpine environments for hidden wildflowers, Helen enjoys trail running, cooking colorful meals, backcountry skiing, and learning about the ever-evolving intersections between people and the environment in the Greater Yellowstone Ecosystem.
