Nancy is an educator by trade and a naturalist at heart. She has been fostering passion for the outdoors and wild places since she first became a naturalist leader in junior high school. Before coming to Yellowstone, she was an English teacher and an Arizona Wilderness Steward, doing trail maintenance, eradicating invasive species, and reporting illegal use of wilderness areas. Now, she combines her experience in education with her love of the park to help lifelong learners look closely at nature. She takes her passion for the outdoors south for the winter, working as a naturalist in Arizona. She speaks Chinese conversationally and Spanish fluently.

Mike Rosekrans has been leading trips and environmental education programs around the Western United States for over a decade. Growing up in the Great Lakes Region of the Upper Midwest, Mike took a keen interest in the natural world at a young age. He received his bachelors degree in outdoor recreation from Winona State University in Minnesota and promptly moved west to begin his career and pursue his passion of exploring and teaching in the mountains and forests of the Western United States. In 2016 Mike completed his graduate studies, earning an M.Ed from Western Washington University in Partnership with North Cascades Institute. While in graduate school Mike began developing an interest in the ecology and natural history of grizzly bears and upon graduation spent a summer season in Denali National Park before permanently moving to Yellowstone where he was able to realize his dream of teaching programs related to grizzly bear natural history while also developing and implementing curriculum-based youth programs within Yellowstone National Park. Mike is a passionate guide who hopes that in providing people with a more holistic view of the Yellowstone Ecosystem that people will be inspired to preserve, protect, and make sound decisions in preserving our natural world.
