Katherine Mongé, Former Pelosi Senior Counsel, to join Capitol Tax Partners

Capitol Tax Partners is pleased to announce that Katherine Mongé, a Senior Counsel to former House Speaker Nancy Pelosi will be joining our firm as a partner beginning in June.

Katherine is a tax and trade policy expert who brings a wealth of bicameral legislative experience that will enhance the firm’s ability to offer best-in-class strategic and technical advice on legislative and regulatory policy matters before the Congress and the Administration.

Speaker Emerita Pelosi said, “As a foremost expert on tax and trade, Katherine Mongé was an essential asset to my Speaker’s Office, our House Democratic Caucus and the entire Congress. Crafting legislation to negotiate free trade agreements, reinvigorate American research and manufacturing, realign our tax code with our values and more, she was involved at the highest levels of every major economic initiative of the last decade. While she is missed on Capitol Hill, Katherine brings to Capitol Tax Partners a deep reservoir of law-making experience and strategic expertise that is rivaled by very few.”

Jon Talisman, Capitol Tax Partner's co-founder and managing partner, said, "We couldn’t be happier to have Katherine join our team at Capitol Tax. She offers a unique blend of political savvy, tax and trade policy expertise, and outstanding judgment. Katherine has a proven legislative track record of success and is well-liked and respected on both sides of the aisle, throughout both the Hill and the Administration.”

During her decade-long tenure serving as Speaker Pelosi’s chief policy advisor on tax, trade, economic, and budgetary issues, Katherine was a lead negotiator on numerous legislative accomplishments. Among the most notable are passage of the Inflation Reduction Act of 2022, the most significant climate package in U.S. history; renegotiation and passage of implementing legislation of the United States-Mexico-Canada Agreement (USMCA), which garnered the support of both the Republican Administration and the AFL-CIO; several Covid relief packages, including the Coronavirus Aid, Relief and Economic Security (CARES) Act and the American Rescue Plan; and several tax extenders packages, including the Protecting Americans from Tax Hikes (PATH) Act of 2015.

Prior to her time in the House, Katherine worked for Senate Finance Committee Member Ben Cardin (D-MD) as a tax and trade counsel and policy advisor on banking, human resources, and general economic issues. Katherine also worked as a transactional tax attorney at Mayer Brown LLP.

Katherine earned a Juris Doctor degree (cum laude) from Boston College Law School and a Bachelor of Science in Foreign Service degree from Georgetown University. Originally from Duluth, Minnesota, Katherine began her career working as a legislative assistant to Senator Mark Dayton (D-MN).
