District 2 City Councillor Bill Linehan has tapped a former candidate for state representative as his aide. Mark McGonagle will start in Linehan’s office on June 4, replacing Tim Brown.

McGonagle, who ran for the Fourth Suffolk District seat in the House in 2010, said the new job is a “good opportunity to come home again, so to speak.”

McGonagle is a South Boston native and his wife Kathlin grew up in Dorchester’s Harbor Point neighborhood.

Aside from taking a brief break for the 2010 run for office, McGonagle has worked as a youth development specialist at the Boston Public Health Commission since 2008. In that job, he focused on the issue of substance abuse, something the South Boston neighborhood and parts of Dorchester frequently struggle with.
