Vision 2020

Future home of Cotter Schools

Work has begun on the Vision 2020 building project! Thanks to an incredible gift from the Steve and Barbara Slaggie Family Foundation, renovation of the existing Roger Bacon building is underway to create a 21st century classroom building. 

Initial schematic designs call for renovation of all existing classrooms, construction of a cafeteria, and the building of a new residence hall for boarding students - all on the current site of Roger Bacon Center.
