The U.S. Department of Energy Office of Environmental Management posted an updated its organization chart last month that lists Thomas Mooney as the new chief of staff.
Sources said in December that Mooney, a former U.S. Department of Defense senior manager, was becoming the new chief of staff at the environmental cleanup office although the Energy Department declined to confirm the appointment at the time.
Mooney joins the Energy Department after serving as chief of staff for the Pentagon’s Office of the Chief Management Officer since October 2017 where he helped oversee business operations, including the DoD’s financial plan. Mooney spent most of 2017 as a deputy White House liaison for the Defense Department. Between 2009 and 2017, Mooney was a project lead and analyst at Virginia-based LMI Management Consulting where he worked on strategic planning and communications.
The last permanent chief of staff at the Office of Environmental Management was Darcey Bolin who came to the agency in 2018 from CH2M to work under then DOE Assistant Secretary for Environmental Management Anne Marie White. White resigned in June and Bolin left DOE in July.
The latest management chart, dated Dec. 9, also shows that former Deputy Chief of Staff Joceline Nahigian has left that job to become acting deputy manager for intergovernmental affairs and stakeholder engagement.
