The Danbury Public School District has appointed an interim principal for the school being rented in Brookfield to accommodate kindergartners.  The Danbury Primary Center in Brookfield will be led by Janet Sayegh.  Kindergartners from South Street, Ellsworth Avenue and Stadley Rough elementary schools will be bussed to the former St. Joseph School on Obtuse Hill Road this fall.  The veteran teacher most recently served as a lead teacher at Pembroke School.   She's been employed by the district for 13 years.
