Alex was born and raised in Springfield, IL and grew up reading field guides whenever he wasn’t out looking for turtles and frogs. He can still vividly remember
the first Great Blue Heron he saw and it was this modern day dinosaur that sparked his interest in birds. He moved to Olympia, Washington to study ecology at The Evergreen State College where his love of natural history continued to grow. While studying abroad in Chile Alex discovered a passion for sharing his love of natural history as well as getting into birding as a hobby. Straight out of undergrad Alex attended Western Washington University to obtain a Masters in Environmental Education, which included a yearlong residency teaching and writing curriculum at the North Cascades Institute. In the ten years since finishing grad school he has worked naturalist and outdoor education jobs in Oregon, California, Maine, and back to Washington. For two years he managed education and outreach programs for the New Mexico Wildlife Center. There he delivered live raptor programs, cared for non-releasable birds, mammals, and reptiles as well as assisting in the rehabilitation of injured wildlife.
Alex came to Jackson Hole in 2022 to join Wildlife Expeditions as a Guide and loves sharing the magnificent wildlife and scenery of the Greater Yellowstone Ecosystem with visitors. When he’s not guiding, Alex can be found birding, cross-country skiing, or hiking with his adopted husky, Mia.

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.

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.
