 A new Montessori preschool is coming to Roanoke County. Chris and Sarah Milehand plan to admit 70 youth to a half-day preschool set to open in January. They've purchased a franchise for Ivy Brook Academy, which will employ both the Montessori method and the Reggio Emilia approach. The school, featuring an outdoor classroom, is located beside Oak Grove Elementary School and may eventually expand to 205 students with morning and afternoon sessions.
