PORTLAND — City Councilor John Anton said Monday he will not seek re-election this fall for the at-large seat he has held since 2007.

Anton, 47, said he is stepping aside to focus on his career and to spend more time with his family. He is married with two daughters, ages 7 and 10.

“The work’s important – I enjoy it,” he said. “I definitely plan to stay involved in a public affairs and civic affairs.”

Anton is currently self-employed as a consultant specializing in real estate and community development finance and policy.

Prior to starting his own business last year, Anton worked for the Portland nonprofit Northern New England Housing Investment Fund, serving as vice president from 1997 to 2000 and president from 2000 to 2011.

Anton currently leads the City Council’s Finance Committee and serves on the council’s Transportation, Sustainability and Energy Committee. He previously served on the Planning Board and as a Portland Housing Authority commissioner.

Anton did not rule out a future run for City Council or other elected offices.

At-large City Councilor Jill Duson and District 3 City Councilor Edward Suslovic are also up for re-election this year.
