William B. Gannon was recently named Special Agent in Charge of the U.S. Department of State’s Diplomatic Security Service (DSS) Boston Field Office. In this role, he oversees all Bureau of Diplomatic Security operations in Massachusetts, Maine, New Hampshire, Vermont, and Rhode Island.

Special Agent Gannon is the nineteenth law enforcement professional in his family. “Given my family’s extensive commitment to city, state and local law enforcement in New England, I am particularly honored that the State Department has entrusted me with this vital position. I look forward to collaborating with our law enforcement and government partners for whom I have the utmost respect,” said Gannon.

The DSS Boston Field Office is one of eight regional offices across the United States that form the backbone of Diplomatic Security’s domestic mission: protecting high-ranking visiting foreign dignitaries; supporting the protection of the U.S. Secretary of State and other officials; conducting criminal, counterterrorism and background investigations; and coordinating security support for foreign missions, diplomats, and consulates in the United States. The Boston Field Office works in close cooperation with other federal, state, and local law-enforcement authorities.

Gannon most recently completed a year-long program at the U.S. Naval War College, in Newport, RI, where he earned an M.A. in National Security and Strategic Studies. Prior to the Naval War College, he served as the Regional Security Officer at the U.S. Embassy in Santiago, Chile.

Gannon began his career as a DSS special agent in 1999; his first assignment was in the Chicago Field Office. Follow on assignments included Manila, Philippines, the Boston Field Office, the Secretary of State’s Protective Detail and Shanghai, China.

In addition to an M.A. from the Naval War College, Gannon holds an M.A. from Boston University in International Relations, a certificate from the Georgetown University Leadership Program, and a B.A. in History from Westfield State College. In preparation for his overseas assignments, he also studied Mandarin and Spanish at the Foreign Service Institute.

Gannon is the recipient of the Department of State’s 2016 Equal Employment Opportunity Outstanding Leadership Award, the 2012 Overseas Security Advisory Council Distinguished Achievement Award, several Department of State Superior and Meritorious Honor awards, as well as numerous commendations and citations.

The Bureau of Diplomatic Security, Diplomatic Security Service (DSS), is the U.S. Department of State’s law enforcement and security arm. DSS special agents, engineers, and security professionals are responsible for the security of more than 270 diplomatic missions around the world. In the United States, DSS personnel protect the U.S. Secretary of State and high-ranking foreign dignitaries and officials visiting the United States, investigate passport and visa fraud, and conduct personnel security investigations.
