However, the ocean called Luke back to the Cape where he has worked as a park interpreter, a fisheries observer, and most recently as an oyster farmer. He joined BCWC in spring 2022 with the goal of helping to protect the local waters and habitats he enjoyed as a youth. Luke currently lives in Mashpee with his wife Kacey and their many pets, where you can also still find him out exploring the Cape’s ponds, marshes, and woods.
