John F. Clark is president and CEO of the National Center for Missing & Exploited Children, the nation’s leading nonprofit organization at the forefront of child protection for more than 37 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 348,000 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 five years. He has an 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 more than 360 employees and offices in four states, including Virginia, New York, Florida and Texas. During the pandemic, Clark found innovative ways to ensure that travel and other COVID-19 restrictions did not impact NCMEC’s mission to help missing and sexually exploited children 24/7. He also stepped up prevention efforts at a time when schools were shuttered and children were spending significantly more time on the internet.
For 23 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 38 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 of Science degree from Syracuse University.
