  • 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.
