The Reverend Stanislaus Szadinski was the new pastor organized a staff of sisters from the Felician Order whose motherhouse was located in Coraopolis, PA. After being a pastor from only two months and re-opening the school, he was transferred to be replaced by Rev. Louis A. Phillips. He orchastrated a more modern catholic school in 1946 that included a spacious and well-supplied social areal for the parishioners that is housed in the basement of the school still known as Seton Hall. After serving seventeen years in the parish, he was transferred and replaced by Rev. Patrick K. Maher, on Setp. 22, 1952. Rev. Maher accomplished a new section of the St. Casimirs Cemetery in April of 1956, and purchased the Valentine property across the street from the church. The building was remodeled into a new convent for the Sisters. Work was completed in 1958, and the convent still remains there today. Rev. Edward Kakascik was appointed administrator that year and instituted building funds for a new church and rectory in 1964. In August of 1968, the cornerstone of the new church was blessed and Sunday Mass was offered. on April 29, 1969, the new church was dedicated. From that day forward, dramatic drops in scholastic enrollment occurred. Rev. Francis J. Baudo replaced Fr. Kakascik on April 9, 1973. By December 30, 1978, Fr. Baudo received word from the Provincial Superior of the Felician Sisters that they could no longer continue to staff the St. Casimir School; hence their ministry as religious educators. The sisters withdrew from Adena and Dillonvale Catholic Schools.
