initially, classes were taught almost entirely by priests from the archdiocese of indianapolis and benedictine sisters of beech grove. many sisters were housed in the convent on-site, but their numbers declined to the point that in the 1970s, their convent was converted to an annex of the school. the annex has served as classroom, office and storage space for thirty years, and was recently rededicated to the sisters as the st. benedict center.
