Piwowar is chosen as superintendent

Tim Piwowar, the school district’s assistant superintendent for finance and operations, has been named its next superintendent. The School Committee’s vote to offer the position to Piwowar, 35, was unanimous. The former Billerica Memorial High School math teacher was one of four finalists for the district’s top job. The others were William Hart, assistant superintendent for the Pentucket Regional system; Steven Stone, administrator of special education services in Peabody; and William McKersie, associate superintendent for academic excellence for the Catholic Archdiocese of Boston’s schools, who withdrew his name from consideration last month. Piwowar is expected to step into his new role on July 1. His biggest priority will be to help the district complete a long-awaited comprehensive master plan to address the needs of its aging schools. Anthony Serio retired as Billerica’s superintendent last July, and Bill Ryan has been serving as the district’s interim superintendent. - Brenda Buote
