As she starts to build her administration, Mayor-elect Muriel E. Bowser picked an unfinished city office building to introduce her transition team Friday morning.

Bowser stood in the lobby of the old police department warehouse on Shannon Place SE, now nearly transformed into a glassy new home for various city agencies, and talked up her commitment to “closing the gaps” in the District’s growth as she takes over from fellow Democrat Vincent C. Gray.

“Education gaps, job gaps, income inequality gaps, economic development gaps,” she said. “I pledged … this administration would have a consistent presence east of the river … to work on an agenda that’s feasible, that’s visionary, that’s funded.”

The personalities she has tapped to start that process are plenty familiar with the city and its politics. The co-chairs, she said, will oversee a transition process that will involve eight subcommittees evaluating policies and personnel in the coming months. They include:

 The four living former mayors of the District of Columbia. Two of them, Marion Barry and Sharon Pratt, attended Friday’s announcement. Adrian M. Fenty and Anthony A. Williams did not.

 John Boardman, the executive secretary-treasurer of Unite Here Local 25, an outspoken advocate for hotel and restaurant employees and for workers at large.

 Maria Gomez, the founder and executive director of Mary’s Center, a pioneering community clinic serving the low-income and minority communities.

 Beverly Perry, a former Pepco government affairs executive, who took an early role in organizing the transition effort.

 Alice Rivlin, a former White House budget director and current Brookings Institution fellow, who has been involved in D.C. fiscal issues for decades — including a stint chairing the congressional control board more than a decade ago.

 Mary Gooden Terrell, a former D.C. Superior Court judge and founder of the High Tea Society, known for advocating for members of low-income communities in the criminal justice system.

Members of Bowser’s campaign and council offices are staffing the transition, based in the city’s One Judiciary Square building, including strategist John Falcicchio, fundraiser David Jannarone, spokesman Joaquin McPeek and policy adviser Lindsey Parker.

Additional members of the transition team will be named next week, Bowser said. The eight subcommittees, aides said, will correspond to Bowser’s policy platform which focused on the areas of education, economic development, public safety, housing, transportation, environment, health, and government accountability.

McPeek said Friday that residents will be invited to participate in the transition process, with more details to come next week.
