Matt works with leading maritime and marine terminal clients on a broad range of compliance issues, including environmental, safety, citizenship and “Jones Act” coastwise compliance. He has represented leading energy companies in key Jones Act rulings and investigations that have shaped domestic petroleum trade, and structured complex Jones Act compliance ownership structures.

Throughout his career, Matt has built strong relationships with U.S. government officials, trade associations, and the local legal and lobbying community. He guides international businesses in their dealings with the Departments of State, Treasury, Commerce, and Transportation, as well as independent regulatory agencies and Congress.
