Matt M. Dummermuth assumed leadership of the Office of Justice Programs as Principal Deputy Assistant Attorney General in September 2018.

Matt is a Justice Department veteran, having served most recently as U.S. Attorney for the Northern District of Iowa from 2007 to 2009. Under his leadership, the U.S. Attorney's Office – in close coordination and cooperation with federal, state and local law enforcement in the largest law enforcement operation in Iowa history – successfully orchestrated the nation's most successful criminal immigration worksite enforcement action. The action resulted in the convictions of more than 300 illegal immigrants for various document fraud, aggravated identity theft and other immigration-related offenses, and the convictions of the company's day-to-day CEO, CFO, controller, operations supervisors and entire human resources department for various bank fraud, document fraud and related offenses.

Under his leadership, the U.S. Attorney's Office also prosecuted record numbers of child exploitation defendants and launched an Internet-predator warning program that reached more than 42,000 students in 150 middle schools. In addition, he created the first human trafficking task force in Iowa, bringing together law enforcement agencies and victim assistance organizations to combat trafficking operations and provide services to trafficking survivors. During his tenure, the office also convicted 26 defendants, including 19 doctors, for illegally distributing more than 30 million prescription pills using 500,000 phony prescriptions, and shared with local law enforcement more than $4 million of the $7 million seized from the two Internet pharmacy companies and other defendants involved in the illegal scheme.

Matt previously served in the Justice Department as Counsel and Special Assistant to the Assistant Attorney General for Civil Rights, and as a Special Assistant United States Attorney in the Eastern District of Virginia. Prior to joining OJP, Matt was in private practice in Iowa where he focused primarily on civil litigation involving constitutional, governmental, agricultural and business matters. In addition, Matt represented more than 300 female parolees in state felony parole revocation matters and advised more than 2,000 inmates in five Iowa prisons about their constitutional and civil rights relating to their convictions and conditions of confinement.

Matt graduated from Harvard Law School, where he was editor-in-chief of the Harvard Journal of Law & Public Policy, and clerked for the Honorable Judge David R. Hansen of the U.S. Court of Appeals for the Eighth Circuit. Prior to law school, Matt grew up on a crop and livestock farm in Iowa and graduated with a degree in agricultural engineering from Iowa State University. Matt and his wife Becky have five children.
