WASHINGTON, D.C. (November 9, 2026) – GuidePost Strategies, a leading government affairs and strategic advisory firm, is pleased to announce the addition of Abbie Sorrendino to its team as Principal.
As a veteran senior staffer of the New York Delegation in both chambers, Sorrendino brings rare insight into Democratic leadership in both the House and Senate. Her legislative strategy and advocacy expertise strengthen GuidePost's ability to deliver wins for clients.
“Abbie is one of the most respected and well-connected operators on Capitol Hill, and we are thrilled to welcome her to GuidePost. Her experience at the highest levels of the House and Senate, and her ability to turn complex policy challenges into results, will be a tremendous asset to our clients and our team.”
Sorrendino served as Chief of Staff, and previously Legislative Director, for Congressman Joseph D. Morelle (D-NY), where she advised the House Committees on Rules, Armed Services, and Appropriations and oversaw a legislative agenda that included financial services, transportation, infrastructure, campaign finance reform, and government oversight. She steered critical bicameral legislation on surprise medical billing, tech hubs, and emergency COVID-19 relief. During the 2022 midterms, she was a key political and fundraising adviser to the Congressman's re-election campaign.
Sorrendino was also a longtime Leader Chuck Schumer (D-NY) staffer and worked on the Rules committee in the Senate under his leadership. She managed hearings and bill mark-ups, and her portfolio spanned Legislative Branch oversight, election administration, and presidential inaugurations. She served as the Vice Chairman’s staff liaison to the Joint Congressional Committee on Inaugural Ceremonies for the 2017 Presidential Inauguration and held a senior role in preparations for the 2013 Inauguration.
Sorrendino has designed legislative and advocacy strategies for clients across financial services, defense and aerospace, consumer products, transportation, and other industries.
Sorrendino began her career as a staffer on Barack Obama's 2008 presidential campaign and as an AmeriCorps VISTA volunteer in Syracuse, NY. She holds a B.A. in Political Science and History from Le Moyne College and an M.A. in Political Science from Northeastern University.
