This ceremony marks her as the 25th individual to hold the position of Ambassador Extraordinary and Plenipotentiary from the U.S. to Luxembourg.
“As I step into the role of U.S. Ambassador to Luxembourg, I am honored to build on the strong foundation of our shared history and excited by the opportunities ahead. Having spent my career growing businesses and championing innovation, I see tremendous potential to broaden our cooperation, particularly across business ventures, defense modernization, space innovation, advanced technologies, and the financial sector – areas where our partnership offers unique opportunities for meaningful impact.
I look forward to working closely with the government, private sector, and Luxembourg’s vibrant community of innovators. I believe our partnership can serve as a model for how two like-minded nations, united in ambition, can turn shared vision into transformative results for our economies, collective security, and our people,” said Ambassador Feinberg.
Feinberg has had a broad career in business, media, sports and entertainment. She has served as a judge at venture capital competitions and participated as a speaker on industry panels. As an advisor and investor committed to supporting women entrepreneurs, she has helped many launch their careers and expand their businesses.
She began her professional journey at Bob Woolf Associates in Boston—her father’s law firm specializing in sports and entertainment—where they managed contracts for over 500 clients including Larry Bird and Joe Montana. Feinberg also established the firm’s literary division that produced several bestselling autobiographies.
Her academic background includes lecturing at Harvard Law School; participation in Harvard's “Getting to Yes” Negotiation Series; attending Harvard Business School’s program on Entertainment, Media and Sports; and earning a B.S. from Northwestern University.
