Brian Barthelemes is the town’s newest selectman, after beating out two other candidates in a recent special election. “My first reaction after the election was that I was grateful for all of the support I received,” said Barthelemes, 51, a global business development executive with IBM. “I’m excited about it and I’m looking forward to serving on the board.” He received 421 of the 694 votes cast for the seat left vacant by the April resignation of Gary Young. The term expires in May 2015. The other candidates on the Sept. 28 special election ballot were Nancy Leonard, who came in second, and Mark Christensen, who came in third. Barthelemes, a native of Wakefield who, with his wife, JoAnn, has two teenagers, just finished a seven-year run on the local advisory committee. “I’ve been doing town budgets for the last 7 years, so I felt I could add value to the current board,” he said.
