After 40 years, the head of Nyack’s branch of the NAACP is stepping down. Dr. Frances Pratt was hailed as a “trailblazer and icon” by Rockland’s Commissioner on Human Rights, Constance Frazier. The Journal News says Dr. Pratt will be succeeded by Nikki Hines, who currently works at the Center for Safety and Change in New City, and chairs the Nyack Housing Board.
