John F. Clark

President and Chief Executive Officer

John F. Clark is president and CEO of the National Center for Missing & Exploited Children (NCMEC), the nation’s leading nonprofit organization on the forefront of child protection for more than 33 years.

Since 1984, NCMEC has helped law enforcement recover more than 250,000 missing kids, distributed billions of missing posters, operated a 24/7 missing children hotline, offered comfort to countless families and trained and provided free resources to law-enforcement and other professionals across the country.

Clark’s extensive law-enforcement background, including 28 years with the United States Marshals Service, has uniquely prepared him to lead the Alexandria-based organization, whose mission is to help find missing children, reduce child sexual exploitation and prevent child victimization. He was appointed director of the USMS in 2006 by then-President George W. Bush as its ninth director, a post he held for five years.

In this digital world, child sexual exploitation has exploded. Since the Internet has no boundaries, NCMEC operates the CyberTipline, a centralized mechanism for reporting suspected child sexual exploitation. During his two-year tenure at NCMEC, Clark has seen an exponential rise in these reports, with 10 million reports made to the CyberTipline in 2017 alone. 

What makes NCMEC truly unique is its 30,000-foot view of the evolving threats to our nation’s children. NCMEC’s experience and data is the foundation of its safety programs, and Clark is passionate about analyzing and sharing this knowledge with families and communities to better protect children.

Clark oversees a staff of more 340 employees, hundreds of volunteers and offices in five states, including Virginia, New York, Florida, California and Texas. Before joining the USMS, Clark worked for the U.S. Capitol Police and U.S. Border Patrol. He earned a Bachelor’s of Science degree from Syracuse University. Before taking the helm at NCMEC, Clark was director of security at Lockheed Martin Corp., the nation’s largest defense contractor.
