Jennifer Cunningham, one of the most powerful women in New York politics, is exiting SKDKnickerbocker in March to travel and explore new challenges, according to an email sent to staffers.

The SKDKnick partner is former political director of the powerful 1199SEIU union and a long-time friend of Governor Andrew Cuomo.

She handled Cuomo’s first run for governor and the successful 2011 bid to legalize same-sex marriage in the Empire State.

City & State NY ranked Cunningham and then-SKDKnick partner Josh Isay No. 1 in its inaugural Political PR Power 50 list released Jan. 13. It lauded Cunnigham as “one of New York’s savviest communications strategists.”

SKDKnick elevated Isay, who was campaign manager for New York Senator Chuck Schumer, to CEO on Jan. 16 and named five new partners.

He promised, “an incredibly exciting year for SKDK as we actively pursue companies to acquire, new talent to come in-house and deliver an even better and more robust product for our clients.”
