At all times one of the priests of the town was chaplain to the school. It was almost always a priest serving in Bride Street and some of them served only a very short time in the school before moving on. Back in the 1920s, Fr. Ryan and Fr. George Murphy were chaplains. Fr. Cardiff is perhaps one of the best remembered. He was a regular visitor to the school and encouraged the children to attend 10 o'clock Mass on Sunday mornings. Indeed he often came to the school to complain if there wasn't a big attendance there. Fr. Keating succeeded Fr. Cardiff.
In the forties some pupils remember Fr. Paddy Doyle and Fr. O'Neill. For twenty-two years the school children all knew Fr. Mattie Doyle. He invariably arrived about 10 minutes before lunchtime and delayed the class until they were well late going home. He loved Fatima and Lourdes and always brought home souvenirs from these places to the children. He brought pens, medals, rosaries, Holy Water fonts and gave them away generously each time. Every class got a present from Fr. Matty. He reminded the children over and over again to get their parents to go to the Confraternity - Monday night for women and Tuesday for men. He visited the girls in the secondary school too and they formed two sections of the Womens’ Confraternity at one time. When Fr. Matty left the school he was presented with some travelling cases by the staff and pupils. Off he went to Lourdes and Fatima again and one day he returned to see the children - bringing the suitcases full of sweets for everyone.
Chaplains to the school since 1970 have spent a relatively short time in it. Fr. Greg Byrne, Fr. Bernie, Fr. James L. Curtis, Fr. John Jordan, and Fr. Hugh O'Byrne have come and gone . The present chaplain is Fr. Jim Fegan. Now that the town is divided into 'Watch' areas the school has become a centre of prayer and meetings for Fr. Fegan's area.
