William J. Bratton
Peter A. Luukko
Commissioner Bratton is one of the world’s most respected and trusted experts on risk and security issues. During a 46-year career in law enforcement, he instituted progressive change while leading six police departments, including seven years as Chief of the Los Angeles Police Department and two nonconsecutive terms as the Police Commissioner of the City of New York. He is the only person ever to lead the police agencies of America’s two largest cities.
As the Executive Chairman of Teneo Risk, Commissioner Bratton advises clients on risk identification, prevention, and response. Teneo Risk addresses four key areas: Anti-Terrorism Preparedness; Crisis Preparedness & Response; Cyber Security & Data Protection; and Smart City Planning.
Prior to assuming his role at Teneo Risk, Commissioner Bratton was the 42nd police commissioner of the City of New York from January 2014 to September 2016. It was the second time he had held the post. During that time, he oversaw 32 months of declining crime, including historic lows for murders and robberies. Commissioner Bratton spearheaded a major technological overhaul, the Mobile Digital Initiative, which gave a smartphone with custom-designed apps to every officer and put a tablet in every patrol car. Commissioner Bratton also implemented major reforms to the NYPD’s counterterrorism program by developing two new units—the Critical Response Command (CRC) and the Strategic Response Group (SRG)—which now provide the city with more than 1,000 highly trained and properly equipped officers who are dedicated to counterterrorism, large-scale mobilizations, site security, and rapid deployment citywide.
In the 1990s, Commissioner Bratton established an international reputation for re-engineering police departments and fighting crime. As Chief of the New York City Transit Police, Boston Police Commissioner, and in his first term as New York City Police Commissioner, he revitalized morale and cut crime in all three posts, achieving the largest crime declines in New York City’s history. As Los Angeles Police Chief from 2002 to 2009, in a city known for its entrenched gang culture and youth violence, he brought crime to historically low levels, greatly improved race relations, and reached out to young people with a range of innovative police programs.
Mr. Bratton also currently serves as the Vice Chairman for the Secretary of Homeland Security’s Advisory Council.
