Rick Lagina is an American television personality, treasure hunter, and executive producer best known for his central role on the History Channel reality series The Curse of Oak Island. A retired U.S. postal worker from Kingsford, Michigan, Rick became fascinated with Oak Island after reading about it in a 1965 issue of Reader's Digest as a child. Together with his brother Marty, he purchased a portion of Oak Island in 2005 and has since led one of the longest-running treasure hunts in history. His unwavering dedication, blue-collar work ethic, and signature catchphrase 'Once in, forever in!' have made him a fan favorite across twelve seasons of the show. Beyond Oak Island, Rick has appeared in the spin-off series Beyond Oak Island and continues to inspire treasure-hunting enthusiasts worldwide.
