# Director of the Naval Criminal Investigative Service

The director of the Naval Criminal Investigative Service leads the Naval Criminal Investigative Service (NCIS) agency as it investigates and defeats threats from across the foreign intelligence, terrorist, and criminal spectrum by conducting operations and investigations ashore, afloat, and in cyberspace, to protect and preserve the superiority of Navy and Marine Corps warfighters.

## History

In 1993, the NCIS mission was again clarified and became a mostly civilian agency. Roy D. Nedrow, a former United States Secret Service (USSS) executive, was appointed as the first civilian director and the name changed from Naval Investigative Service Command to Naval Criminal Investigative Service (NCIS). NCIS was aligned as an echelon two activity under the Secretary of the Navy, via the General Counsel. Nedrow oversaw the restructuring of NCIS into a Federal law enforcement agency with 14 field offices controlling field operations in 140 locations worldwide.
In May 1997, David L. Brant was appointed director of NCIS by Secretary of the Navy John Howard Dalton. Director Brant retired in December 2005. He was succeeded by Director Thomas A. Betro, who was appointed director of NCIS in January 2006, by Secretary of the Navy Donald C. Winter. Betro retired in September 2009. On September 13, 2009, deputy director of operations Gregory A. Scovel was appointed acting director by Under Secretary of the Navy Robert O. Work. He served concurrently as deputy director for operations until the new director was selected.
On February 14, 2010, Mark D. Clookie became the fourth civilian director of NCIS, having been appointed to the position by Secretary of the Navy Ray Mabus. On October 7, 2013, Andrew L. Traver became the fifth civilian director of NCIS, having been appointed to the position by Secretary of the Navy Ray Mabus. On June 4, 2019, Omar R. Lopez became the sixth civilian director of NCIS, having been appointed to the position by the Secretary of the Navy, Richard V. Spencer.
