Robert Parish
Dominican High School opened in September 1956, with 174 freshmen from 26 parishes. Although sponsored by the Sinsinawa Dominicans, the school was championed by two pastors, Peter E. Dietz, pastor of St. Monica Parish (1912–1947) and Farrell P. Reilly, pastor of St. Robert Parish (1912–1958). Both envisioned the formation of a Catholic high school in the North Shore suburbs. St. Monica Parish donated the land for Dominican High School and St. Robert Parish contributed over half a million dollars for its construction.
