Naturalists
More than just nature guides, our naturalists are engaging storytellers, each with their own rich experiences and fascinating tales from the field. They are as different as their specialties—which range from geology to zoology—and their knowledge about the natural world runs wide and deep. And while they are schooled in science, they have a knack for describing species and natural phenomena in relatable ways, whether explaining the behavior of a brown bear to an elementary school student or describing the physics of glacier formation to a Ph.D. holder. They know their destination inside and out and, often, they call it home.
Our naturalists are also inspiring travel companions who participate fully in the expedition, leading excursions and also joining guests at meals or in the lounge over drinks. Each team is made of naturalists with a range of specialties, so you can set out with a botanist on a morning hike and then take an afternoon Zodiac ride with a marine biologist. Or if a naturalist shares a particular passion of yours—say birding or geology—you can choose to join the excursions they lead. Our guests have been known to book another trip just to travel with a particular naturalist again.

Dennis Cornejo
Dennis has spent more than half of his life working with Lindblad Expeditions. He first studied biology in the Sonoran Desert. It was his work with the Arizona-Sonora Desert Museum that brought him into contact with Sven Lindblad. Dennis was working with sea turtles in Mexico, desert tadpoles in southern Arizona and evaluating various legume trees for arid lands agriculture throughout the Sonoran Desert. Sven asked him if he would be interested in working on a ship as a naturalist in Baja California… a simple ‘yes’ turned out to be perhaps the most important decision he ever made! At first, life as a Lindblad naturalist, working during the winter while on break from university, exploring Baja California while guiding and lecturing, was a positive feedback loop for his academic goals. Spending time with guests, who possessed incredible amounts of life experience and enthusiasm, soon eroded Dennis’ dreams of a career in Academia. However, during this time he earned a master’s degree with a thesis on the reproductive strategies of Sonoran Desert toads and a PhD with a dissertation on the mechanical design and biogeography of columnar cacti (large cacti including the saguaro and the cardon). For almost 40 years Dennis has explored and learned with Lindblad. At first in the Sonoran Desert, then the temperate rainforest of Southeast Alaska, the topical rainforests of South America and Oceania and many, many other places: dry to wet, hot to cold. As his world experience increased, so did Dennis’ interests… from reptiles and amphibians, to flowering plants, insects and other invertebrate and lichens. He also worked for 15 years as an Undersea Specialist diving and making videos from Antarctica to Svalbard to Papua New Guinea. Now he is out of the water and on the tundra, so what next? With Lindblad Expeditions there is no limit with the whole world to choose from!

Bud Lehnhausen
Bud received an undergraduate degree in wildlife biology at Colorado State University. He then immediately went to Alaska where he worked and lived for 30 years. At the University of Alaska, Fairbanks, Bud studied wildlife biology and received a master's degree conducting research on four species of alcid seabird nesting on a remote island in the Gulf of Alaska. For a number of years he worked as a research biologist studying various fields, including moose/habitat relationships, songbird populations in relation to succession, tundra bird populations and migration, and woodpecker populations after natural forest fires. Since 1983, Bud has worked as a naturalist and expedition leader with Lindblad Expeditions-National Geographic. During these years he has traveled in the Arctic and Antarctic, temperate and tropical regions of Central and South America, Atlantic Ocean crossings, and the western South Pacific. These numerous voyages over the years have given him a chance to appreciate diversity of life and cultures which he finds fascinating. In addition to traveling, Bud is an avid natural history photographer and his wife writes children’s books on natural history illustrating them and using Bud’s photographs. Having built their own super-insulated house in Fairbanks over a 20 year period, in 2003 they relocated their family to northern Colorado. They are in the process of being owner/builders of a new energy efficient passive solar home in the foothills above Fort Collins.

Doug Gualtieri
Doug Gualtieri has worked as a Naturalist interpretive guide for over 20 years, beginning his career in Denali National Park and Preserve at a remote wilderness lodge leading hikes and giving lectures on the ecology and wildlife of that region. Later he began leading Lindblad Expeditions land extensions to Denali in 2002 and has worked with Lindblad in some form or another ever since. With a background in Biology and a lifelong passion for the natural world Doug moved to Talkeetna, Alaska in 1999 from his home state of Michigan, and never looked back. Having studied many facets of the natural world, from general ecology to animal behavior, Doug found a strong connection to the life of birds; primarily because birds tie together so many components of our world, making them perfect teaching tools. But, also because almost all of them fly, and that’s pretty cool. Doug and his wife make their home today in the quaint, and at times, bustling Alaskan community of Talkeetna. Living in their cabin home in the boreal forest complete with a pristine salmon stream, Doug and his wife spend their time with their dogs on hikes, skis, or bikes enjoying the beauty of Alaska and the thriving community they live in.

Santiago Imberti
An ornithologist, photographer, fisherman, climber, and writer, Santiago Imberti was born and raised in southern Patagonia, Argentina. He obtained a degree in tourism and later in ornithology, which allowed him to combine his love for nature and the outdoors with his work as a birdwatcher, naturalist, fly fishing, and mountain guide. He has been guiding trips in Patagonia, the Antarctic, and Arctic for some 25 years. However, his main passion is conservation and research therefore off the ships Santiago does field work on birds, mostly in southern Patagonia and is the President of Asociación Ambiente Sur; an NGO that seeks to protect the environment and educate the new generations on a sustainable way of life in southern Patagonia. From 2009 to 2014 he has coordinated the project to save the now critically endangered Hooded Grebe, which is an endemic bird in Patagonia; and the creation of Patagonia National Park, a massive protected area that aims to save the grebe and some of the least know habitats in South America. His many articles and stories have been published in scientific journals, popular travel magazines, books, and since his singing abilities are rather poor, he has produced a couple CDs of the beautiful bird sounds of South America, Patagonia, and Antarctica. He lives in Punta Arenas, southern Patagonia, Chile, with his wife and son.

Joshua Hall
Joshua Hall was born in Panama City and raised in the highlands of the Chiriquí province. He studied ecotourism at a university in Panama and is currently pursuing a degree in tourism business administration. His love of nature can be attributed to a lot of time spent traveling with his mother, a nurse at the Social Security Hospital. In 1983, a foundation called Abundant Life was created in Panama. The foundation was made up of a group of doctors and nurses with a passion for helping those in need. They were pioneers in going to communities in Chiriquí, sometimes hiking more than 12 miles, where they took medicine, meals, and other needed items, often opening up trails guided by the indigenous residents. Joshua participated as a child with his mother and developed a love for nature, rainforests, mangroves, coral reefs and the indigenous communities of Panama. He has retained a love of volunteering from his childhood and currently volunteers for an NGO, Afotur, in a tourism development program that sends provisions to a local community on the Chagres River. At his young age, he has already developed an extensive knowledge of the history of the Panama Canal, as well as the ecology and culture of Panama. He enjoys travelling throughout the country learning about culture, history, traditions, and the flora and fauna.

John Pailthorpe
John spent the early years of his life in London, before an inspirational teacher took him to the highlands of Scotland on a school adventure trip. From then on the natural world has been his passion. After teacher training in Bangor, North Wales, John began a thirty-year career in outdoor education centres and schools, teaching and leading children and adults in such pursuits as mountaineering, rock climbing, kayaking, and sailing throughout the U.K. and Europe. During this time John took time out to be part of six polar scientific expeditions, as a field assistant/guide. Two of these were with the British Antarctic Survey; the first a two-month field expedition to the Eklund Islands on the Antarctic Peninsula; the second, eight months as part of a king penguin and elephant seal study on South Georgia. He served as a boat skipper/field guide on a geological expedition to the northwest of Svalbard. More recently, he took part in three expeditions to the Greenland ice cap for the Scott Polar Research Institute of Cambridge, as part of the European Space Agency's “Cryosat” project. John is well aware that his career, and the wonderful experiences it has included, all began with one special teacher. With this in mind, he likes nothing more than to pass on his enthusiasm for nature and all things outdoors, with the intention of promoting an awareness and caring attitude towards the natural environment.

Robin Patten
The natural world has always been central to Robin’s life. At an early age, she was out exploring the Montana backcountry, learning natural history through experience. She went on to earn a PhD in ecology from Colorado State University, and later expanded her graduate studies to include environmental history and cultural geography. This allowed Robin to explore and better understand the interactions between cultures and landscapes. Scotland was the country that sparked Robin’s interest in environmental history, for it is a country where history is visibly written in the earth – an archive of the land. In the past two decades Robin has studied, volunteered, and traveled extensively throughout Scotland, always considering the relationships between time, people, and place in shaping the landscape. A Post-Graduate Diploma from Scotland’s Centre of Mountain Studies expanded her knowledge of Scotland’s cultural history, natural environment, and the interactions between the two. Robin recently moved from the mountains of Montana to the high desert of southern Utah. She now resides in the small town of Bluff, surrounded by another landscape where the stories of the past people are visible in the surrounding canyons and mesas.
