Greta Peisch brings nearly 15 years of experience in international trade matters. Most recently, she served as General Counsel for the Office of the United States Trade Representative (USTR) where she was a primary legal advisor to the agency, including with respect to trade enforcement and trade agreement implementation and negations.

While at UTSR, Greta led the USTR’s enforcement agenda, including World Trade Organization (WTO) and trade agreement dispute settlement and implementation of Sections 201 and 301 of the Trade Act of 1974.  

Greta negotiated the settlement of significant trade disputes, including a years-long dispute with the European Union regarding large civil aircraft; disputes related to the U.S. imposition of tariffs on steel and aluminum and the EU’s retaliatory tariffs; and a dispute with Canada related to a U.S. solar safeguard measure. In addition, she led the implementation of the first-ever reviews and panel request under the novel Rapid Response Labor Mechanism of the U.S.-Mexico-Canada Agreement. She also oversaw negotiations related to Critical Minerals Agreements with Japan, the EU, and the United Kingdom and advised on legal issues in trade agreement negotiations and implementation, including with respect to the Indo-Pacific Economic Framework (IPEF) and the U.S.-Taiwan Initiative on 21st Century Trade.

Prior to her time at USTR, Greta was Senior International Trade Counsel for the U.S. Senate Committee on Finance. In this role, she developed policy positions and legislation concerning trade policy, including the renegotiation of the North American Free Trade Agreement (NAFTA) and the drafting, passage, and implementation of the Trade Facilitation and Trade Enforcement Act of 2015, the United States-Mexico-Canada Agreement Implementation Act, and the Miscellaneous Tariff Bill Act of 2018.

With additional experience involving digital trade, labor, and the environment, Greta is poised to help clients navigate all aspects of trade's legal landscape.
