SCARBOROUGH, Maine — Three newly elected town councilors on Wednesday were sworn into office, while Councilor Jessica Holbrook, previously vice chairwoman of the council, was unanimously elected its chairwoman.

Taking seats for a 2015-2017 term were incumbent Councilor Katherine St. Clair, who joined the council two years ago; Shawn Babine, a banker and former three-term councilor; and Peter Hayes, a health care consultant and member of Dog Owners of Greater Scarborough.

Also at the Wednesday meeting, Councilor Jean-Marie Caterina was elected council vice chairwoman.

On Nov. 4, voters ousted Richard Sullivan and James Benedict from the council by decisive margins.

Babine won election with 4,340 votes, Hayes with 4,280 and St. Clair with 4,026. Sullivan and Benedict received 3,678 and 1,630 votes, respectively, in the seven-candidate, three-seat race.

Entrepreneur William Somers received 3,158 votes and former Scarborough Economic Development Corp. board member Roger Beeley garnered 2,230 votes.

Holbrook, 33, of Beech Ridge Road, was first elected to the council in 2009. On Wednesday, she outlined goals she sees for the panel, including the need for congeniality, respect and “to agree respectfully to disagree.”
