Eric Hersey, who was communications director for the House Committee on Financial Services under chairwoman Maxine Waters, has joined Mercury.
He helped shape messaging for issues such as consumer protection, housing affordability and availability, diversity and inclusion, technology and pandemic response.
Earlier, Hersey served as communications director for the National Community Reinvestment Coalition, where he worked on fair lending, housing finance reform and implementation of the Dodd-Frank measure.
He began his political career in the offices of New York Senators Hillary Clinton and Kirsten Gillibrand.
Charlie King, Mercury partner, said Hersey will prove a “major boost to our media relations practice.”
