Two of his campaign staffers will be joining Felix Arroyo, the incoming city councillor at-large, at City Hall when his term starts on Jan. 4.

Stuart Rosenberg, who was a senior campaign adviser, will be Arroyo's chief-of-staff. Joy DePina, his deputy campaign manager, will be his director of constituent services.

Rosenberg has worked on a number of local campaigns, including for state Sen. Jarrett Barrios and state Rep. Linda Dorcena Forry. He is also a former aide to City Councillor Michael Ross.

DePina has worked as a health care organizer for Northeast Action.

Both hail from Dorchester, with Rosenberg living in the Adams Village/Fields Corner section, and DePina a resident of Uphams Corner.

An additional two staff positions are expected to be announced at a later date.

Arroyo finished third in the November election, behind City Councillors At-Large John Connolly and Stephen Murphy, and ahead of fellow incoming Councillor At-Large Ayanna Pressley.
