  • Doug Gualtieri

    Naturalist
    Doug’s passion for the natural world started at an early age in his home state of Michigan. He received two biology degrees from Central Michigan University, and later went on to get a master’s degree in conservation biology. His education led him to study a diverse range of natural sciences, with an emphasis on ecology, animal behavior, and migratory birds. Shortly after leaving the academic world, Doug migrated north to Alaska with his trusty Siberian husky, Koda. He began working as a naturalist in Denali National Park in 1999. For over seven years he has shared his love of Alaska and Denali’s six million acres with Lindblad Expeditions-National Geographic guests, as trip leader for the Denali Land Extension based at the North Face Lodge deep within the park.

  • Ella Potts

    Naturalist
    Ella’s passion has always been in marine conservation, with a childhood spent swimming, kayaking or boating in the chilly waters of the UK, or surveying the marine life of those waters from windswept headlands. She has numerous, distinct early memories of shivering adults, wrapped up in jumpers and cagoules, looking down at her with slight horror through sheets of rain and commenting on her short sleeves. A phenomena that persists to this day.  She graduated with a Masters degree in Marine Biology: Conservation and Resource Management from Swansea University, setting her up for a career protecting those marine ecosystems that she so loves. Ella has worked for several British whale conservancy charities, including ORCA and the Hebridean Whale and Dolphin Trust (HWDT) and is a British Divers Marine Life Rescue (BDMLR) marine mammal medic. She has a real passion for lecturing, and during her time in these different organizations has presented to vastly ranging audiences; from groups of young children right up to filled auditoriums at the headquarters of HWDT partner, WWF.

  • Peter Webster

    Undersea Specialist
    Born in Scotland, Peter became fascinated with nature and wildlife from a very young age. This early interest led to him earning a degree in conservation biology followed shortly after by an M.Sc in marine and fisheries ecology. He is currently studying for another M.Sc in digital mapping. After working as a commercial diver for several years Peter was offered the position of Field Diving Officer with the British Antarctic Survey in 2012. He then spent the next 16 months in the Antarctic, stationed at Rothera Research Station, on the peninsula where he managed the dive operations and a team of scientific divers working on a wide range of research on climate change, ocean acidification, and increased seabed disturbance by icebergs. As well as diving Peter also spent several months in the Antarctic deep field working in aircraft operations, depot laying, and meteorological work whilst living in tents in conditions below -30oC.
