Additionally, Tim has first-hand experience in formulating integrated security plans from his service in the FBI, which includes serving as the FBI liaison to the US Secret Service for the 2009 presidential inauguration in Washington, DC, as well as leading the FBI efforts to investigate numerous threats to members of Congress and cabinet officials. As a private consultant Tim has assisted high-net-worth individuals, universities, and defense contractors in the design and implementation of security plans that featured physical security assessments, cyber monitoring, and executive protection.

Tim frequently speaks on matters ranging from active shooter incidents and acts of terrorism to multifaceted law enforcement matters. He has appeared on, or been quoted by, CNN, NBC Nightly News, FOX, The Washington Post, Reuters, and NPR, among other outlets.

As the special agent in charge of the FBI’s Newark, NJ office, he led the more than 800 professionals of the agency’s seventh-largest field division in their efforts to bolster national security and combat crime and cyber threats.

Earlier in his FBI career, Tim was the chief of the FBI Financial Crimes Section, where he was responsible for global oversight of FBI casework involving insider trading, market manipulation, and corporate fraud. Tim led the FBI investigative team that investigated the illicit manipulation of the LIBOR interest rate, which resulted in numerous prosecutions of individuals and corporate entities in the US and abroad.
