In 1915, twenty two years after the creation of the parish, the new pastor, Msgr. Charles Kavanaugh, saw the imperative need for a parochial school. An application for five Sisters, Servants of the Immaculate Heart of Mary, to open a school was accepted.
During his twenty year tenure , the original grade and high schools were built, a convent for the Sisters was purchased, and the Grotto was constructed. He was regarded as one of the most brilliant speakers among the Catholic clergy. To the youngsters of St. Katharine’s School, he was a gentle and kindly soul. To the tired and disheartened, he came with strong faith and optimism, always hopeful, giving to others something of the love and joy which inspired his own life.
