ROCKLAND, Maine — Residents will have a choice when they vote over the next several weeks to fill a vacancy on the city council.

Adam Ackor and Michael Herbert have filed papers and gotten on the June 14 ballot.

The seat was vacated in early March by William Jillson, who resigned, citing the inability to work with other councilors or the city manager.

Ackor, 46, grew up in Cushing and has lived in Rockland for 20 years. He has a bachelor’s degree from the University of Maine and owns Shore Village Builders, a general contractor business. He is married with two children and lives on Old County Road.

He also serves on the city’s comprehensive planning commission.

Herbert is employed by Regional School Unit 13 as a van driver. For 13 years previously he managed the Working Waterfront newspaper published by the Island Institute in Rockland.

Herbert is a Rockland native and graduated from Rockland District High School. He earned two bachelor’s degrees from the University of Maine — in recreation and park management and in secondary education.

He lives on Mechanic Street with his wife and they have adult children.

Absentee ballots will be available at the city clerk’s office starting May 16.

The term will run through November 2018.
