Actum, which was launched by Mercury Public Affairs staffers in 2022, has acquired New York-based Kirtzman Strategies.

Andrew Kirtzman has been a fixture in the New York media and political scenes.

The former WCBS-TV and New York Daily News political reporter, and New York magazine contributor, also advised the NYC Board of Education chancellor during the deBlasio and Bloomberg administrations,

Kirtzman is the author of two books on Rudy Giuliani. He published “Rudy Giuliani: Emperor of the City” in 2000, and “Giuliani: The Rise and Tragic Fall of America’s Mayor” in 2022.

Michael McKeon, Actum partner and former communications director for New York governor George Pataki, said the Kirtzman Strategies acquisition represents a milestone in the firm’s growth and expansion in New York.

The acquired firm provides strategic communications and crisis management services to clients such as the Metropolitan Museum of Art, Brooklyn Botanic Garden and Montefiore Health.
