  • Andy Wolff

    Assistant Expedition Leader
    A Midwestern kid with an insatiable curiosity about places far and foreign, Andy has converted a lucky break after college into a career at sea. From swabbing the decks to advocating for artisans and zooming in Zodiacs, he knows the operation from every department on board. What keeps him fresh after nearly two decades working at sea is waking up somewhere new every morning, the day ahead a blank slate with no way of knowing what marvels nature and serendipity may bring his way. Andy looks forward to sharing this sense of wonder and possibility with guests as they venture together into new realms with Lindblad Expeditions-National Geographic.

    Expedition Leader
    Brent Stephenson was born in New Zealand and has been a birder since childhood, and in 2005 completed his Ph.D., studying the breeding biology of Australasian gannets in New Zealand.  In 2003, along with Sav Saville, co-owner of their bird-guiding business, he rediscovered the “extinct” New Zealand storm-petrel, a bird known previously from only three museum specimens collected during the 1800s.  With support from National Geographic, he led a team conducting further research on this enigmatic seabird.

  • Colin McNulty

    Naturalist/Expedition Diver
    Colin grew up scuba diving with his family, and fell in love with the ocean at an early age.  He has been fortunate to dive in many exotic corners of the world, and to work on a number of undersea research projects studying whale sharks and several deep water fish species.  After graduating from the University of Vermont, he began working in various capacities aboard expedition ships.  During his travels he photographed and shared his adventures as a way of making remote areas and cultures more accessible.  It was in Santa Barbara, California that he learned how to photograph underwater, and combined two of his great passions, photography and the sea.  Exploring and documenting the vast richness, diversity, and beauty of the underwater world continues to be a lifelong endeavor.

  • James Hyde

    Undersea Specialist
    James is your typical free-range Pacific Northwest outdoorsy type. Born in Seattle and reared nearby on Vashon Island, he is most comfortable in slightly cold and damp weather. James joined the Lindblad team in July 2016 as a dive buddy and has been in love with expedition travel since. On his own he has traveled to Europe, Asia, and Australia, but with Lindblad he hopes to continue his adventures across the globe, searching out the beauties of the natural world. An avid scuba diver James can’t help being excited about whales, sharks, and pinnipeds, but he will also happily bend your ear about underwater slugs and invertebrates. It’s best just to humor him about these things.
