President Obama plans to nominate Denise Turner Roth to head the General Services Administration.

Roth, currently the deputy administrator, would replace Dan M. Tangherlini, who left the top position in February. Roth has been serving as acting administrator since then. Previously, she was the city manager of Greensboro, N.C., a legislative affairs assistant to former District Mayor Anthony Williams and an aide to two members of Congress.

“As Acting Administrator and Deputy Administrator, Denise led the General Services Administration to become more efficient, innovative and effective,” Obama said in a statement Thursday. “Denise is a capable leader whose experiences in management will serve our nation well. I thank Denise for agreeing to continue her public service and look forward to working with her in this important position.”

GSA may not be as well known to the public as other agencies, but it plays an important role in helping those agencies serve the public. It is the government’s landlord, providing workplaces and business services for federal operations.

“I am honored to lead GSA in transforming the way our government serves the American people,” Roth said. “Today GSA is smarter and stronger, and I look forward to building on this momentum — creating new opportunities for the federal government and the nation.”

Roth once worked as a legislative assistant for former representative Jim Moran (D-Va.), who called her “a terrific choice.”

“She’s just so impressive,” he said. “She lights up a room when she walks in. She’s perfect in every way that matters. She’s smart. She’s honest. She’s hardworking. She is a visionary and great communicator.”
