Washington, D.C. – Today, Congressman Seth Moulton (D-MA) announced that Massachusetts native Alexis Prieur L’Heureux will be his new Chief of Staff. Alexis joins the staff today and will be based in Moulton’s Washington D.C. office. Alexis assumes this position from interim Chief of Staff Carrie Rankin, who will be transitioning into a senior advisory role.

“Alexis brings a vast level of experience to this role and I am excited to welcome her to the team,” said Moulton. “With her leadership, we can continue to advance a forward-looking legislative agenda, deliver results for the Sixth District, and bring real change to Washington. I am excited that she will be joining my team and look forward to working with her as I continue to serve my constituents and our country.”

Alexis served in President Obama’s Administration as a national security policy advisor at the Department of Defense (2009-2012, 2014-2017) and as the Deputy Executive Secretary at the U.S. Department of Treasury (2013-2014).

“I am excited to be joining such an innovative and ambitious office,” said L’Heureux. “It is clear that Seth’s commitment to service, passion for our country, and unique approach to getting things done in D.C. drive the culture of his team, and I am honored to be assuming a leadership role within the office. I look forward to continuing the tradition this team has of being transparent, mission-oriented, and service-driven.”

In addition to her leadership in the Department of Defense, Alexis has also worked to protect the vote for numerous campaigns at both the state and national levels, starting with then-Senator Obama’s 2008 primary campaign in New Hampshire. In 2017, Alexis co-founded two organizations focused on voting rights: Access Democracy and Voter Protection Partners. Access Democracy, a non-profit that recently became a project of The Leadership Conference Education Fund, works to increase access to voting by improving how elections are run at the local level. Voter Protection Partners works with Democratic committees, state parties, and campaigns to build programs that help ensure eligible voters are able to cast their ballots.

Alexis is a naturalized citizen and a graduate of Queen’s University in Canada and Northeastern University School of Law. Alexis resides in Washington, D.C., with her husband and their young son.
