Daniel M. "Dan" Tangherlini is a former Administrator of the United States General Services Administration. Unanimously approved to the post by the United States Senate on June 27, 2013, he had served as Acting Administrator since his appointment by President Barack Obama on April 2, 2012. He earlier served as an executive in the U.S. Department of the Treasury, as City Administrator of Washington, D.C., and as interim General Manager for the Washington Metropolitan Area Transit Authority.
Tangherlini began his career as a Presidential Management Fellow at the Office of Management and Budget in 1991. He progressed through several positions in his time at OMB, and he transferred to the United States Department of Transportation in 1997. he worked for the United States Secretary of Transportation, where his work included Amtrak labor settlement negotiations and development of new approaches to infrastructure financing.
In November 1998 Tangherlini was loaned to the District of Columbia government, where he served as acting Chief Financial Officer for the Metropolitan Police Department (MPD). The position became permanent, and he remained in the role until May 2000, and then as the director of the District of Columbia Department of Transportation (DDOT) until February 2006.
Tangherlini then succeeded Richard A. White as interim General Manager of the Washington Metropolitan Area Transit Authority, which operates the Metrorail and Metrobus systems in the Washington, D.C., area. He withdrew from consideration as Metro's permanent General Manager in November 2006 after accepting the position of City Administrator in the cabinet of Adrian Fenty, then Democratic nominee for Mayor. Fenty and Tangherlini each signed letters of intent agreeing to join forces.
Tangherlini was named Acting Administrator of the U.S. General Services Administration on April 2, 2012, after the abrupt resignation of former Administrator Martha Johnson following the White House's discovery of the findings of an Inspector General's investigation into the misuse of taxpayer funds for an October 2010 employee conference in Las Vegas.
On May 22, 2013, President Barack Obama announced his intent to nominate Tangherlini as Administrator of the General Services Administration saying, “As Acting Director, Dan helped restore the trust of the American people in the General Services Administration by making the agency more efficient, accountable and transparent. I want to thank Dan for his leadership over the past year and for agreeing to continue serving in the Administration."
On January 15, 2015, Tangerhlini has announced plans to step down at the GSA (on February 13, 2015), according to a letter to GSA employees. Deputy Administrator Denise Turner Roth will take on the role of acting administrator until President Obama chooses a replacement.
