One of the nation’s oldest children’s services organizations will experience its first leadership transition in 24 years. Philip Coltoff, longtime chief executive officer of the Children’s Aid Society, will retire on October 21 after more than half a century of working for children’s rights. He will be replaced by C. Warren “Pete” Moses, the current executive director. Coltoff started his career in 1956 as teen director at the Williamsburg YM/YWCA, and joined the Children’s Aid Society ten years later. He was named executive director and CEO in 1981. During his tenure, the organization launched its signature community schools initiative, a joint effort with Department of Education to offer in-house health and social services in public schools. It also made significant progress in programs designed to provide foster care, prevent teen pregnancy and encourage enrollment in public health insurance. CEO-to-be Moses has worked for the organization since 1964, and was appointed executive director in 2002. Moses was a key figure in the development of the organization’s community schools program and led the creation of its first five schools in Washington Heights.
