Steven Dicterow, who previously served three terms on the City Council, announced Wednesday that he will run for reelection in 2012.
He said he is running because he sees a shift in city policy from his core beliefs.
"When I was first elected I had a personal agenda — public safety, fiscal responsibility, doing more for kids and art — which was largely accomplished in my first two years on the council," Dicterow said. "I spent the next five years making sure my agenda was carried out.
"I see the city drifting away from what my agenda was, and I think it is important."
Dicterow last served on the council in 2006, and he juggled city business and family obligations with a demanding career. He has served on the Festival of Arts' board of directors in the interim.
However, a change in his professional life will allow him to devote more time now to community issues, he said.
