John F. Clark

John F. Clark is president and CEO of the National Center for Missing & Exploited Children, the nation’s leading nonprofit organization on the forefront of child protection for more 36 years.

Since 1984, NCMEC’s mission has been to help find missing children, reduce child sexual exploitation and prevent child victimization. The organization has helped law enforcement recover more than 311,000 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 has served as NCMEC’s leader for four years. He has extensive law-enforcement background, including 28 years with the United States Marshals Service. Before joining NCMEC, Clark was director of security at Lockheed Martin Corp., the nation’s largest defense contractor.

As CEO, Clark oversees a staff of nearly 350 employees and offices in four states, including Virginia, New York, Florida and Texas. In December 2018, Clark ushered in a new era for NCMEC as the organization moved to its new headquarters in Alexandria, Virginia.

For 22 years, NCMEC has operated the CyberTipline, a centralized mechanism for reporting child sexual exploitation. During his tenure at NCMEC, Clark has seen an exponential rise in these reports, with more than 35 million reports made to the CyberTipline in the last two years alone.

Throughout his career, Clark has been a leading child advocate. During his tenure at USMS, Clark implemented and administered Title I of the Adam Walsh Child Safety and Protection Act, which directed USMS to locate and apprehend fugitive sex offenders. He also oversaw the implementation and operation of the National Sex Offender Targeting Center.

Clark 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. 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.
