LENOX â Veteran eastern Pennsylvania educator and administrator Marc J. Gosselin has accepted a four-year contract as the new superintendent of the townâs public school district. Under the terms of the agreement, Gosselin, 43, will start July 1, with a first-year salary of $160,000, followed by unspecified increases thereafter, committee Chairman Robert Vaughan told The Eagle. He was selected unanimously by the School Committee on Jan. 29. Second-place finisher Beth Choquette, a North Adams native and Cheshire resident who is an elementary school principal in Northampton, also had impressed School Committee members with a strong interview last week. Gosselin, a native of Dracut in Eastern Massachusetts, was a finalist for superintendent of the larger Dover-Sherborn school district in Bostonâs western suburbs. But, the 15-member joint School Committee and superintendent search committee there failed to reach consensus at a meeting Monday, opting instead to gather more information on Gosselin and another leading choice.
