Mayor Marty Walsh rolled out several new appointments to his administration today in his first full day as the city's chief executive.

Joyce Linehan, one of Walsh's top political advisors for years, will be the chief of policy, Walsh announced at a 1:15 p.m. press conference. Linehan lives in Lower Mills and has served as chairwoman of the Ward 17 Democratic Committee.

Linehan told reporters that the post was "too much of an honor to pass up." She added: "It's my dream job, really."

Joe Rull, who once worked as a special assistant to Mayor Tom Menino for nearly a decade, will head the city's Chief of Operations. Rull, who is a native of South Boston, was one of Walsh's top field directors in last year's campaign for mayor. He has also worked for Governor Deval Patrick.

As first reported yesterday, Rep. Eugene O'Flaherty— a close political ally of Walsh's in the state Legislature— has been named Corporation Counsel— the top legal job in the city.

Trinh Nguyen, most recently the chief of staff at the Boston Housing Authority, will head the Walsh administration's Office of Jobs & Community Services on an interim basis.

Keith Williams, who has worked inside City Hall in a variety of capacities including the Mayor's Office of Neighborhood Services, has been appointed to oversee the Boston Jobs Policy as the interim director of Small Business.

Allejandra St. Guillen will be the head of the Office of New Bostonians. St.Guillen has most recently worked as the executive director of Oiste.

Mayor Walsh told reporters that Rull and O'Flaherty— who both live outside of Boston presently— will have a six month grace period to move into the city.
