Larry has been a naturalist for more than 50 years. His experience includes extensive work in environmental education in Ohio, Vermont and Yosemite National Park where he was program director for the Yosemite Institute. He has been a ranger at Mohican State Park, Lehman Caves National Monument, and Glacier Bay National Park where he first met up with Lindblad Expeditions–National Geographic in 1990.
Since then he has traveled to every continent, from the tropics to both polar regions, rain forests to deserts, wilderness areas to sites of ancient civilizations to some of today's largest, most cosmopolitan cities. Being a naturalist enables Larry to combine his passion for natural history with his training as a teacher. While birds and their adaptations are Larry's first interest, he enjoys viewing the world from an ecological perspective, studying the interrelations among rocks, plants, animals and other elements that affect the biosphere.
