Meet the Deputy Commissioners

Iris Rodriguez-Rosa
First Deputy Commissioner

Iris Rodriguez-Rosa became the First Deputy Commissioner of the New York City Department of Parks and Recreation in February 2022, previously serving as the Bronx Borough Commissioner for the agency.

Rodriguez-Rosa started her career organizing tenants and the community in Williamsburg Brooklyn in the late 1970s under the Federal Comprehensive Employment and Training Act (CETA) program. She then began public service with the City with Brooklyn Borough President Howard Golden as a community Board liaison and later in 1979 became the District Manager for Community Board 4 in Bushwick Brooklyn, deemed then as the youngest ever appointed. Iris began her career at Parks in 1986 serving as Director of Community Boards; continued as an operations manager in upper Manhattan and for the better part of 20 years; and later served as Chief of Recreation in the Public Programs division in both the Bronx and Queens. It was in this capacity that she realized that bringing health & fitness opportunities to New Yorkers was exceedingly important, and that parks and facilities offer the perfect environment for creative programming. It was with her initial efforts and support from Parks that she was able to obtain programming funding from elected officials for events such as movie nights, family days, and concerts.

As of June 2015, Iris has served as the Bronx Borough Parks Commissioner. In this role she helped work with and merge the Friends of Van Cortlandt Parks and the Van Cortlandt Conservancy to become what is now the Van Cortlandt Alliance; she has been a champion along with former Bronx Borough President Ruben Diaz Jr. on the renovation of the Orchard Beach Pavilion; and she has helped execute countless playground renovations for the benefits of hundreds of thousands of New Yorkers across the city. Iris is the adoptive parent to her two nieces Sylvia and Jasmine and helps care for her nephew Jason and grandnephew Amir. Her anchor and best friend are her husband Manny Rosa, and they have five beautiful grandchildren: Noel, Sophia, Annabel, Rafael, and Aaron Jeremiah.
