He served as the Deputy Trade Representative for four years under Ron Kirk, and became the acting Trade Representative when Kirk resigned in March 2013.[2]

Early life and education[edit]

Marantis attended Harrison High School in Harrison, New York.[3] He received a Bachelor of Arts in public and international affairs from Princeton University in 1990. He then attended the Harvard Law School, where he received his juris doctor in 1993.[1] Out of law school, Marantis joined the law firm of Akin Gump Strauss Hauer & Feld, working in Washington, D.C., and Brussels.

Public Sector career[edit]

Marantis joined the Office of the U.S. Trade Representative (USTR) in 1998 as its associate general counsel. In 2002, Marantis joined the U.S.-Vietnam Trade Council, living in Hanoi for two years, aiding United States–Vietnam trade relations.[1] He returned to the United States to work on John Kerry's 2004 presidential campaign as an issue director for John Edwards, Kerry's running mate.[1][4]

Marantis worked for United States Senate Committee on Finance as the chief international trade counsel, starting in 2005. He aided Max Baucus, the committee's chairman, negotiate an expansion of the Trade Adjustment Assistance, and helped secure passage of the Korea-U.S. Free Trade Agreement. The ranking Republican member of the committee, Charles Grassley, praised Marantis for his efforts.[1][4] He was nominated by President Obama and confirmed by the U.S. Senate in early 2009 to serve as the Deputy Trade Representative, in charge of negotiating trade pacts in Asia and Africa and negotiating with China on tariffs and copyright laws.[1]
