Josh Diosomito

Senior Policy Analyst
U.S. Government Accountability Office

Josh Diosomito is a Senior Policy Analyst within the GAO Homeland Security and Justice Team. The GAO is an independent, nonpartisan agency that helps improve the performance and ensure the accountability of the federal government. GAO provides Congress with timely information that is fact-based, objective, and balanced; investigates how the federal government spends taxpayer dollars; and advises Congress and the heads of executive agencies how to enhance government efficiency and effectiveness.

As an Analyst-in-Charge, Josh is responsible for managing performance audits that evaluate programs administered by the U.S. Department of Homeland Security (DHS)—including the Transportation Security Administration (TSA), Customs and Border Protection (CBP), and the U.S. Coast Guard (USCG), among other DHS components. For nearly 15 years, he has been involved in and managed homeland security audits overseeing DHS aviation, border, and maritime security operations and has traveled overseas to conduct field work. He recently led a team examining foreign airport security operations in Cuba and is currently assessing domestic security operations of U.S. airports to prevent active shooter attacks.

As a public servant, Josh also serves as a certified Diversity and Inclusion Instructor and teaches courses on enhancing awareness of diversity and inclusion issues—including implicit bias, workplace civility, and effective listening, among others. As a former Public Policy and International Affairs (PPIA) Fellow, he has dedicated his career towards promoting the inclusion and full participation of underrepresented groups in the public service arena and advocates for their leadership roles throughout the federal government. In Southern California, Josh serves as a Board Member of the Greater Los Angeles Federal Executive Board Diversity and Inclusion Group which promotes diversity and inclusion awareness through increased training and interagency collaboration. He has taught classes and led presentations for international, federal, and local organizations—including International Auditor Fellowship Program, Departments of Defense and Homeland Security, and the Los Angeles County Fire Department, among others.

Josh earned his bachelor’s degree from the University of California, Berkeley and dual master’s degree in public administration and international relations from the Maxwell School of Citizenship and Public Affairs at Syracuse University. Outside the office, he is a devoted husband and father, active faith leader, marathon runner, and weekend golfer.
