Mark advises clients on trade regulations, drawing on his background as an international trade compliance specialist at the U.S. Department of Commerce, Department of Homeland Security and Customs and Border Protection.

Mark’s interest in the international world was sparked by studying abroad as an undergraduate and confirmed by further experiences overseas during law school, when he had the opportunity to participate in a comparative trial advocacy program in Dublin and serve as a clerk to a justice on the Supreme Court of Ireland. Excited at the possibility of a legal career with an international component, Mark chose to earn a Master of Laws in International Business and Trade Law, followed by a summer at the Caux Scholars Program in Switzerland.

After completing his education, Mark took a position in International Trade Administration at the Department of Commerce, where he worked with highly complex trade revenue cases. Mark led and managed antidumping (AD) and countervailing duty (CVD) cases, including investigations, administrative reviews, sunset reviews, new shipper reviews, scope determinations and verifications; advised federal entities on legal issues related to non-tariff barriers to trade; developed litigation strategies; analyzed and interpreted petitioners’ and respondents’ legal arguments; and drafted decision orders. The work taught him both sides of cases in great detail, as well as the perspective of ruling entities.

In an effort to gain a broader, macro-level view of trade policy, Mark later joined the Department of Homeland Security and Customs and Border Protection, where he led and advised on the development of Customs regulations. He provided technical assistance on trade policy to both foreign and domestic government agencies, guided civil enforcement activities, and supported the development of trade strategies. The experience gave him an inside view of how trade policies are developed and implemented by the government—an invaluable perspective that Mark now offers to firm clients.

At Husch Blackwell, Mark advises clients on compliance with export and import regulations, assists with the preparation of submissions to government agencies for licenses and official determinations, and conducts internal investigations of suspected violations and prepares resulting voluntary disclosures. Since early 2022, Mark’s work has focused heavily on export controls and economic sanctions directed against Russia and Belarus.

With a passion for international connections, Mark enjoys the added nuance that cultural components and perspectives add to complex business transactions, and he thrives on the challenge of navigating both culture and complex trade rules. He aims to make each client feel that their matter is the only one on his desk, and he understands the far-reaching implications of trade matters. Mark approaches each case with an appreciation for the effects the result will have not only for the client, but sometimes for an entire nation, and he’s deeply motivated to achieve the best outcome possible.
