Since 2019, Christine Soyong Harley has led SIECUS (Sexuality Information and Education Council of the United States), a national non-profit organization dedicated to advocating for comprehensive sexuality education in the United States. Founded in 1964, SIECUS promotes sex education that is comprehensive, evidence-based, and inclusive, aiming to help people of all ages make informed decisions about their sexual health and well-being. Chris brings extensive executive leadership experience to SIECUS as the former Director of Intergovernmental Affairs for the White House Initiative on Asian Americans and Pacific Islanders under the Obama Administration. Chris is mixed-race Korean American and Piscataway Indian–the indigenous people of Maryland, a single-mom by choice of twin boys, and the first generation of her family to attend college and graduate school. Chris received her B.A. in Politics from Oberlin College and a Masters in Public Policy from the University of Chicago.

SIECUS works on various fronts to achieve its goals, including policy advocacy, resource development, and public education. It provides educators, policymakers, and health professionals with information and resources to support sexuality education. The organization also engages in advocacy efforts to influence public policy and funding related to sex education, working towards a society where everyone has access to the information and education they need to lead sexually healthy lives.
