In 1927 Father Edward L. Gatens, pastor of Saint Patrick Church, Pottsville, planned the building of Pottsville Catholic High School. On October 15, Cardinal Dougherty of the Archdiocese of Philadelphia dedicated the new building at 112 7th Street (now All Saints School) which still bears the engraving "P.C.H. School" above the door. From 1928 to 1955, Pottsville Catholic was a diocesan Catholic high school with the Sisters of Saint Joseph as faculty. Saint Patrick's Grade School, housed in the same building, was a parish school. At that time, Catholic schools in this area still belonged to the Archdiocese of Philadelphia.
