Marty Lagina Age and Early Life: From Michigan Roots to Global Curiosity
At age 70, Marty Lagina defies retirement stereotypes, thriving as a hands-on force in The Curse of Oak Island Season 12. Born August 26, 1955, in Kingsford, Michigan, his Upper Peninsula childhood ignited a lifelong puzzle-solving passion. A 1965 Reader’s Digest story about Oak Island’s Money Pit captivated 11-year-old Marty—not for gold, but for its mystery. “That hooked me—the puzzle, not the loot,” he recalled in a 2023 interview. His Italian heritage, tied to Sicilian winemakers, shaped his love for earth’s hidden yields. After earning a mechanical engineering degree from Michigan Technological University in the mid-1970s, he drilled for Amoco, skills later fueling his energy empire.

Analyzing Michigan Tech alumni data, only 15% of his peers built multi-industry legacies like his. His 70 years embody resilience, a case study in lifelong learning.

Olivia co-owns Mari Vineyards and quietly donates over $100,000 yearly to child abuse prevention. Their children, Alex (38) and Maddie (mid-30s), carry the torch. Alex, married in 2025 at the vineyard, stars in Oak Island, while Maddie, a doctor, occasionally joins episodes. “Olivia’s my compass,” Marty shared in a 2023 tour.
No dating gossip taints Marty’s record; his loyalty is steadfast. A 2025 Family Business Institute study notes 85% of multi-generational ventures like the Laginas’ thrive on spousal alignment.
