Mr. DeWeese joined the DOT OIG in July 2009 and previously served as a Program Director in OIG’s San Francisco field office where he led diverse and high-profile audits of the Federal Aviation Administration’s (FAA) oversight of air traffic modernization infrastructure investments. Notably, his teams scrutinized FAA’s progress and challenges in safeguarding the multi-billion dollar investment in the Next Generation Air Transportation System (NextGen); more recently, he had also assumed the additional responsibility for reviewing FAA’s oversight of airports.His team’s work has been showcased in multiple IG testimonies, and recommendations from their audits have shaped legislation and policy. In 2014, the Council of the Inspectors General on Integrity and Efficiency recognized these contributions with an “Award of Excellence.” In addition to his focus on program accountability, he continues to be a leader through significant mentoring and staff development activities.  

Prior to OIG, Mr. DeWeese managed high-profile, multi-location audits with the Government Accountability Office (GAO) in Atlanta, Europe (Frankfurt, Germany), and Washington, DC. Of particular note is his work in GAO’s European Office for 4 years where he led reviews of a wide range of complex international trade and finance and defense budget issues. As a leader on GAO’s Acquisition & Sourcing Management (ASM) team in DC he oversaw audits of procurement-related issues that cut across the government including reviews of how Federal agencies share and use past performance information in awarding contracts. In addition to his 12 years with GAO, he spent another 10 years as a senior management and program analyst with the U.S. Army Headquarters in Heidelberg, Germany where he focused largely on civilian and military personnel management.

Mr. DeWeese graduated from Western Kentucky University with a Bachelor’s Degree in Government and Economics in 1983 followed by an MBA in 1986 with an emphasis in management.
