St. Bernard High consolidated into Kuemper Catholic High in 1979. St. Bernard Elementary occupied the former high school building while the former elementary building closed that year; that building was demolished in 1980, and by 2014 two houses had been built in its place. Christ the King School formed in 1983 as a merger of St. Bernard along with Mount Carmel, Lidderdale and Maple River Catholic schools. The Christ the King School, along with the Holy Trinity Catholic grade school, consolidated into Kuemper Catholic System in 2003.

St. Bernard Church became the owner of the former St. Bernard High/new St. Bernard Grade School/Christ the King School. The estate of Mary Nieland funded a renovation of the former cafeteria. This became the Mary Nieland Center, a community center, and as of 2014 other sections of the former school are used for other community and recreation functions.
