CHILD USA is a 501(c)(3) nonprofit think tank that is committed to protecting children and preventing abuse. It was founded by Prof. Marci Hamilton, a national expert on child sex abuse and statutes of limitations, and Rita Swan, who dedicated her life to advocating for children's rights to health and medical care. The organization combines their missions and expertise to provide a comprehensive approach to promoting justice for victims of child abuse and neglect.

CHILD USA's mission is to protect children, prevent future abuse and neglect, and bring justice to survivors through in-depth legal analysis and cutting-edge social science research. They fight for the civil rights of children by advocating for legal reform of statutes of limitations, ending child marriage, holding institutions accountable, fighting for children's access to medical care, and ensuring every child's right to a quality education.

The organization values courage, purpose, integrity, justice, teamwork, and empathy in their work. They also have a sister organization called CHILD GLOBAL that works towards similar goals internationally.
