U.S. Ambassador to Spain and Andorra Julissa Reynoso Rejoins Winston & Strawn

New York—July 16, 2024—Winston & Strawn LLP announced today the return of Julissa Reynoso as a partner in the firm’s New York office and as a member of its Litigation Department. Julissa is an experienced diplomat, policymaker, and lawyer, and was a Winston partner from July 2017 to December 2020.

She rejoins the firm after serving as U.S. Ambassador to Spain and Andorra from January 2022 to July 2024, the first woman to hold the position.

In her role as Ambassador, Julissa oversaw a critical U.S. mission with a host of U.S. federal agencies covering economic, political, and defense and security matters. She was a tireless advocate for American companies doing business in Spain, and supported historic levels of investment by Spanish companies in the United States. During her tenure, Spain served as host of the 2022 NATO Summit and held the presidency of the Council of the European Union.

Prior to being confirmed as Ambassador, Julissa served in senior positions at the White House, including as Assistant to the President and Chief of Staff to Dr. Jill Biden. In those roles, she managed a range of domestic and international matters and served as Co-Chair of the Gender Policy Council, the first policy council focused on gender equity and equality within the Executive Office of the President.

During the Obama Administration, Julissa served as Deputy Assistant Secretary of State in the Bureau of Western Hemisphere Affairs and later as the U.S. Ambassador to Uruguay.

“I’m thrilled to be rejoining Winston at such a pivotal time with the firm’s new leadership team really focusing on growing the client base internationally,” said Julissa. “I look forward to leveraging my experience in Latin America and the Caribbean to support the firm’s mission and helping to advise clients in their business endeavors in this region and throughout the world.”

Julissa will focus on complex commercial litigation, regulatory enforcement, international arbitration, and cross-border disputes. She will provide U.S. and international clients with strategic advice and risk assessment in managing transnational issues.

“Julissa’s exceptional background in international relations will add considerable value for Winston’s clients,” said Peter Crowther, managing partner, international affairs. “Her ties to international clients will also be instrumental in advising their businesses throughout the world including in the United States.”

“We have followed Julissa’s accomplishments in government service with the utmost pride and are privileged to welcome her back to Winston,” said Winston Chairman Steve D’Amore. “Julissa is a prime example of the global talent Winston has attracted through a culture built on cross-practice collaboration, mentorship, and client focus. Thinking and acting as a single global unit is a strategic priority for Winston, and Julissa will be an integral part of that journey.”
