Meet Your Guides


Cara McGary

Owner, Biologist Guide - On a winter visit to Yellowstone, Cara was smitten by the wonder of this "American Serengeti". As a result, she decided that she wanted to spend her life helping others develop and feed their fascinations with the natural world in Yellowstone. Cara is a qualified biologist (B.S. Aquatic Biology and M.S. Biology). Before settling in Gardiner MT, she worked extensively in the forests of Redwood National Park, the outback of Western Australia, and the jungles of Papua New Guinea. When not in Yellowstone, she likes to explore places where there are likely good tidepools or snorkeling.

Nancy Lewis

Senior Naturalist Guide -  Nancy has been a naturalist guide and educator in the Yellowstone area since 2015, but she has been fostering a passion for the outdoors and wild places since she first became a naturalist leader in junior high school. Now, she combines her experience in education with her love of the park to help lifelong learners look closely at nature. With In Our Nature, she leads wildlife and thermal basin tours, guided hikes, and birding trips. Nancy also manages our Week in the Wild program. She takes her passion for the outdoors south for the winter, working as a naturalist guide in Arizona. Nancy speaks Chinese conversationally and Spanish fluently.

Claire Lacey

Biologist Guide - Born and raised in Alaska, Claire developed a passion for wildlife ecology and environmental studies leading her to Montana in 2017 for the opportunity to study the wolves of Yellowstone National Park. Her curiosity prompted a three year, self-directed undergraduate research project, which she finished in 2020 while earning her Bachelor of Science in Fish & Wildlife Ecology and Management from Montana State University. She has spent hundreds of hours watching wolves and studying their interactions with each other and with other species in the Greater Yellowstone Ecosystem. As a CPR-certified tour professional, Claire continues to follow her passion by inviting clients to share the same incredible experiences in Yellowstone that captivated her during her research. She plans to attend graduate school and eventually earn her doctorate with a focus on social behavior in carnivores.

Ben Buescher

Naturalist Guide - Ben developed his passion for wildlife visiting and working as an educator for the zoo in his hometown of Saint Louis, Missouri. He later moved to Fort Collins to earn his bachelor’s degree in Wildlife Biology at Colorado State University where opportunities opened up for him to study in South Africa, Baja California, and CSU’s satellite campus in the Rocky Mountains. At school, he worked as a technician for an acoustic ecology lab where his love for communicating and weaving together the stories of ecosystems blossomed. After graduating, he spent a year as a park ranger and educator for the national wildlife refuge system in Kauai. Landing in Bozeman following his move back to the mainland, Ben is now excited for the opportunity to work as a guide in Yellowstone, using his background in conservation biology and environmental education to share the world-renowned stories of Yellowstone National Park with our guests.

Angela Tempo

Night Sky Guide - After 12 years of working in the corporate sector in sales and marketing, Angela decided to become a Certified First Responder in Natural Disaster. Angela has worked for FEMA and BLM as a swift water rescuer, EMT, and Wildland Firefighter, and has responded to a variety of hurricanes and wildfires. In 2018, she moved to the edge of Yellowstone National Park and has focused her efforts on night-sky and long-exposure photography, as well as wildlife and landscape photography. Angela speaks both Spanish and English.

Kody Marr

Snow Guide - Kody first visited Gradiner, MT back in 2016 while on a 10-day backcountry fly fishing adventure and once he laid eyes on this stunning small town he was hooked, he moved out of his home state of Colorado the following summer and hasn't left since. Kody learned to ski about the same time he was potty trained as he grew up in a ski bum family with his mom being a member of the US Ski Team through his childhood. He now spends his time guiding fly fishing trips during the summer months and guiding over snow activities during the winter months. When Kody isn't in the field you may find him scouting the local mountains for wildlife or traveling the Rockies looking for exotic trout species.

Elizabeth Mordensky

Week in the Wild Special Guest Guide - Elizabeth Mordensky is a naturalist guide and wildlife artist who fell in love with Yellowstone upon her first visit at the age of 12. She has shared her love for Yellowstone with visitors for 6 years as a guide and now promotes conservation for the area’s wildlife on an even greater scale through her art. Her love for backpacking may only be matched by her love for bison, but luckily Yellowstone provides both. No matter where she travels or lives in the world, Elizabeth will always consider Yellowstone home.

Virginia Shoup

Week in the Wild Special Guest Guide - Virginia comes to Yellowstone from a long history in outdoor education and the Girl Scouts. She first worked in the park in 2012, thinking it would be just a fun one- summer job. But after falling in love with the animals, the thermals, and even the lodgepole pines, she never left! Virginia has worked for 10 years as a Yellowstone Naturalist, working with families, teachers, school groups and everyone in between. In the Girl Scouts, she has worked as a summer camp counselor and Leadership Director, and as an international volunteer and Leadership Seminar facilitator. Virginia is a Certified Interpretive Guide, a Leave No Trace Trainer, and a Wilderness First Responder. After the initial shock of her first -30° Yellowstone winter days, this California girl now thrives in the winter and lives for summer hikes and paddle trips. She uses her degree in theater to make science and the outdoors come alive for students of all ages!
