Nearly two months after fire blackened Andrew Jackson Middle School, students, teachers and faculty jammed the halls again Tuesday morning, delighted to be back home. “It’s been wonderful to be back,” said Kelly Phillips, assistant principal at AJMS. “There’s been a lot of excitement in the air. A lot of people have been commenting on how bright the school looks and how clean the walls are.” Steve Mann, a seventh-grade math teacher, said everyone was relieved and eager to get back to normal.
