“The Curse of Oak Island” actually isn’t what brought Marty Lagina and Craig Tester together for the first time, nor is it the only venture the pair have collaborated on. Tester’s history with Lagina actually runs all the way back to their school days, as the duo were roommates during their studies at Michigan Technological University. Throughout their post-academic lives, that friendship has endured.
With both being professional mechanical engineers, Lagina and Tester actually have a history of major partnerships outside of their Oak Island operations. In the 1980s, the pair co-founded Terra Energy, an oil and gas company centered in the state of Michigan. Far more recently, the pair continue to work as co-founders of Heritage Sustainable Energy, a company that focuses on the development of wind farms as sources of renewable energy.
Tester and the Lagina brothers are also on pretty even footing in terms of their Oak Island ventures. Not only does Tester have a stake in the Oak Island Tours business that operates concurrently with the production of “The Curse of Oak Island,” but he also owns part of the island along with his fellow series stars.
