Rokstone Charts New Waters with New Head of Marine

Rokstone proudly welcomes Michael Nukk as our new Head of Marine - North America. Based in New York, he brings a wealth of experience to the table and is poised to navigate our marine division with great success.
Meet Michael Nukk
Prior to joining Rokstone, Mike served as the Head of Marine for North America at AIG for almost five years. His appointment follows the recent addition of Jordan Lanford as Head of Aviation, solidifying the Rokstone commitment to expanding our expertise in specialty insurance lines.
With more than 20 years of experience in the Marine space, Mike spent almost 20 years at Liberty - latterly at Liberty Mutual Insurance, as its SVP Global Marine Practice Leader and Marine Chief Underwriting Officer. Mike spent seven of his 20 years with Liberty working in London as VP Marine, EMEA at Liberty Special Markets.
Embracing New Opportunities
James Potter, Rokstone CEO, is pleased with Mike’s appointment. He said, “There is a need for expertise and superior transactional execution in the middle market Marine space. With Mike’s knowledge and experience, we hope to dominate this space in the market.”
Mike’s mission at Rokstone is nothing short of ambitious, too. Setting sights on growing the Marine portfolio in North America from a startup to a USD 100m within five years - the focus will be on the middle-market North American business, where Mike sees vast potential and untapped opportunities.
With Mike at the helm, Rokstone is ready to embark on a new chapter of marine insurance success. His extensive experience, combined with Rokstone’s progressive and innovative approach is a powerful partnership. As the insurance landscape evolves, Rokstone and Mike are ready to set sail toward new horizons in the marine insurance world.
