Joselyn Fenstermacher

Joselyn Fenstermacher has traveled to all seven continents and brings a multidisciplinary background shaped by work as a firefighter, farmer and field biologist. Raised in the suburbs of Washington, D.C., she developed an early appreciation for time spent outdoors—an interest that has steadily guided her toward a career rooted in field science, conservation and expedition travel.

She studied behavioral ecology and conservation biology as an undergraduate, including research-based semesters in Ecuador and Tanzania. Following her degree, Joselyn worked as a field biologist across the United States, from Alaska to Hawaii, contributing to research and conservation efforts involving species such as endangered fish, brown bears, desert tortoises and rare birds.

These experiences drew her repeatedly to the Chihuahuan Desert, where she spent multiple seasons with the U.S. National Park Service as a biological technician and interpretive park ranger in Big Bend National Park. While working in the park, she completed a Master of Science degree focused on floristic research in 2007.

Joselyn later supported scientific research and operations with the U.S. Antarctic Program at both McMurdo and South Pole stations, including a year managing agricultural systems in Antarctica—among the southernmost farming operations in the world. Since transitioning to expedition guiding in 2013, she has continued to build her understanding of ecosystems around the globe and enjoys engaging guests through shared observation, thoughtful interpretation and on-site learning.
