  • Sean Beckett


    Sean Beckett grew up in the woods of Vermont and became entranced by birds and passionate about ecology from an early age. This upbringing led him to study Biology and Environmental Studies at Vassar College and the University of Vermont. With this formal scientific training, Sean traveled across the United States researching Atlantic puffins, arctic terns, forest owls, songbirds, and raptors. Wildlife research brought Sean to Jackson to work as an ecological cartographer and wildlife technician for the Conservation Research Center of Teton Science Schools. Sean soon began guiding for Wildlife Expeditions to be immersed daily in the amazing diversity of Greater Yellowstone's wildlife, and to share these awe-inspiring experiences with others.

  • Sarah Cayea


    Sarah grew up in the green mountains of Vermont. Her passion for wildlife and wild places began at her rustic cabin deep in the Adirondacks of New York. She obtained a B.S. degree in wildlife biology at the University of Vermont. She has previously worked on non-lethal beaver mitigation, grass land bird research, small mammal trapping and has even prepared zoological specimens for museums. While on a solo cross country road trip with her trusty dog Ginger she fell in love with the Tetons and has never looked back. She loves to share her enthusiasm of this beautiful landscape and animals with her guests and can't wait to have you come along! She is a self admitted "bird nerd" who is rarely far from her binoculars and bird guide.
