New Hampshire has a new State Child Advocate. The Executive Council on Wednesday approved Cassandra Sanchez for the position. She succeeds Moira O’Neill, the first person to hold the position. O’Neill declined to seek a second, four-year term. Sanchez, who was nominated by Gov. Chris Sununu, last worked for the Massachusetts Department of Children and Families as a supervisor in the Kinship unit. She has a background in mental health. The office was created as an independent oversight agency for the state Division of Children, Youth and Families.
