When television viewers tune in to watch Marty Lagina hunt for treasure on The Curse of Oak Island, they see an engineer and entrepreneur driven by a relentless curiosity. Yet, behind the multi-season History Channel hit, Marty maintains a fiercely protected personal life. Fans often search for details about his longtime marriage, eager to look past the heavy equipment, mud, and endless swamp excavations.
Marty Lagina is married to Margaret Olivia Lagina, widely known simply as Olivia. Unlike her husband and their son Alex—who share screen time and public scrutiny—Olivia operates largely out of the spotlight. She isn't a fixture of reality television, nor does she seek out red-carpet events. Instead, her impact lies in quiet business partnerships, professional achievements in energy and agriculture, and a multi-decade marriage that has weathered immense public attention.
The Private Reality of a Longstanding Partnership
Public fascination with celebrity spouses often creates rumors, but Marty and Olivia's relationship predates television fame by decades. Long before the camera crews descended upon Nova Scotia, the couple built a foundation rooted in shared intellectual pursuits and business ventures.
They met years ago, transitioning from longtime friends to life partners. While Marty pursued a degree in mechanical engineering from Michigan Technological University and later earned a law degree, Olivia carved out her own distinct path in the professional world. Rather than playing the traditional role of a passive celebrity spouse, she built a reputation as an active corporate collaborator and entrepreneur.
Professional Foundations in Energy
Long before wine grapes and treasure chests entered the picture, Marty and Olivia made their mark in the energy sector. Olivia spent formative professional years working with companies like Wiser Oil Co. This early corporate exposure provided her with a deep understanding of natural resources, land management, and corporate logistics.
When Marty decided to strike out on his own to launch Terra Energy in the 1990s, Olivia stood alongside him as a foundational co-founder. Terra Energy focused on extracting natural gas from the Antrim Shale formation in Michigan. Operating a booming energy enterprise in the Midwest required rigorous financial discipline, strategic planning, and operational oversight. Olivia contributed directly to these administrative and operational frameworks.
By 1995, the venture had scaled significantly, attracting the attention of CMS Energy, which acquired Terra Energy in a multi-million-dollar buyout. This massive business exit secured the family's financial independence and allowed Marty and Olivia to pivot toward sustainable energy and regional development projects through Heritage Sustainable Energy.
Building Mari Vineyards in Michigan
While the energy sector funded their early ventures, wine production became a shared artistic and agricultural passion. The couple didn't just invest capital into the local Michigan economy; they rolled up their sleeves to establish Mari Vineyards on the Old Mission Peninsula near Traverse City.
Olivia serves as a co-owner of the estate, helping steer a business that has grown into one of Northern Michigan’s premier agricultural destinations. The winery reflects their shared philosophy: honoring local geography while applying innovative techniques. For example, Marty utilized custom-built geothermal systems and specialized hoop-house structures to protect delicate European grape varieties from harsh Michigan winters, while Olivia helped manage the administrative and corporate side of the enterprise.
Their son, Alex Lagina, stepped into a major operational role at Mari Vineyards, transforming the family business into a multi-generational enterprise. Their daughter, Maddie, pursued her own professional interests outside the immediate spotlight, maintaining the family's preference for privacy regarding their children's day-to-day lives.
Media Scrutiny and Low Public Profile
Reality television exposes families to intense public curiosity. Shows like The Curse of Oak Island turn ordinary engineers and treasure hunters into global figures, inviting speculation about everything from net worth to marital status. Despite this cultural phenomenon, Olivia has maintained a strict boundary between public entertainment and private life.
She makes rare, subtle appearances on television or promotional material, usually tied strictly to family milestones or winery events rather than the treasure hunt itself. This deliberate distance shields their personal lives from tabloid culture. It's a strategy that has kept their household stable for decades, proving that a high-profile media career doesn't require a public-facing spouse.
Beyond business and television, the couple engages in regional philanthropy. Through entities like Croft LLC and local community initiatives, they support children's advocacy centers and educational programs in Michigan, focusing their giving close to home rather than seeking national headlines.
