The leader of the New York City Impact Community, NYC Service, is a division of the NYC Office of the Mayor focused on building partnerships to deepen and expand civic engagement through volunteer and service programs, creating sustainable change for the city's greatest needs. It was launched in April 2009 in response to President Barack Obama's national call for volunteerism, which had a goal of engaging 100 million Americans in service by 2020. 

New York City was the first “City of Service” and since NYC Service’s inception, there have been over 200 U.S. cities to follow, establishing the “Cities of Service” network. In terms of national service work, NYC Service currently administers 4 AmeriCorps programs in addition to convening the national service community in NYC to share best practices and resources and to work on common challenges.
