How Did The Curse Of Oak Island's Lagina Brothers Make Their Money?

One of the Lagina brothers was already well-off before the show began — but is investing his wealth to help his brother realize a dream he has had since he was a boy. Rick may have ultimately been the catalyst for this show and for the crusade to ever take place, but his brother Marty has fronted the majority of the money needed in the search. Rick had a career as a postal worker in Michigan prior to his retirement and move to full-time Oak Island explorer, while his brother had a much more lucrative career in his early life.

Marty studied to be an engineer at Michigan Tech and worked for a major oil firm after graduating in 1977. He would work there for several years while also working toward a degree in law from the University of Michigan. After his graduation in 1982, he would found his own natural gas company that would become a pioneer in natural gas extraction. Over a decade later he would sell the company for around $60 million and use that money to invest, launch another energy start-up company, and purchase a vineyard in his home state of Michigan.

Both of the brothers are thought to have increased their overall net worth since the premiere of "The Curse of Oak Island" in 2014 despite only finding a few bits of "treasure" here and there through their drilling. So, even though they have most likely spent millions of dollars on searching for the treasure on Oak Island, they aren't hurting financially.
