  • Luke Correale

    Assistant Expedition Leader
    Growing up in Connecticut, a love of the outdoors was cultivated in Luke from a young age, as he spent most of his time on the water exploring its coast. His mother, a laboratory scientist and master naturalist, and his father, a fine-woodworker and sailor, enrolled him in Audubon summer camps, encouraged and nurtured his fishing skills, and allowed for hours of uninterrupted time in the woods. Throughout high school and college Luke worked as a first mate on a classic Sportfishing vessel out of Montauk, NY. He also worked in guest services at a local seaside hotel where he developed a rich appreciation of all peoples.

  • Shawn Gardner

    Naturalist
    Shawn was reared in the north-woods of Wisconsin, where he spent most of his free time camping, hiking, and fishing with his grandfather. Several years of urban dis-quiescence while attending the University of Wisconsin wrought a post collegiate flight (via beater pick-up truck) to Alaska in 2007. He has spent the subsequent summers submerged in the Bush, guiding at numerous remote lodges, and garnering an intimate relationship with a variety of salmonids, as well as their good friend: Ursus arctos horribilis. When Alaska's rivers harden, he trades his tents and tarps for the turquoise tranquility of the Caribbean. His USCG Captain's credential allows him to harness the wind and ply these waters in search of the frolicking sea turtles and vibrant reefs which all but demand the donning of a snorkel for further investigation.
