The 15-year veteran of Capitol Hill worked for Democratic Representatives Baron Hill (IN) and Melissa Bean (IL) prior to Carney.
CEO John Green and chairman Stewart Hall head Washington-based Crossroads.
Green co-founded the firm along with Federalist Group, which was acquired by Ogilvy PR Worldwide.
Hall helmed Federalist and went on to the managing director post at Ogilvy.
He praised Hart for her "strategic vision" and "proven ability to navigate the House Democratic Caucus as well as tested experience as a political operative."
