Mayor Larry O'Brien is making major staff changes to his office to guide him through the last 14 months of the current term.

Brent Colbert is the Mayor's new Chief of Staff. He has been with the Mayor since his election win.

 Lindsay Valente is leaving her post as Director of Communications. She is replaced by Jasmine MacDonnell.

MacDonnell was the former communications director for federal cabinet minister Lisa Raitt. She resigned after a tape with private conversations with Raitt made national headlines.

Four other new-hires will join the mayor's office in the upcoming weeks.
