Welcome to St. Joseph’s BNS Clondalkin
St. Joseph’s B.N.S. is a Catholic school in Clondalkin village. The school is child- centred and community focused, welcoming all children from all nationalities and religious backgrounds. The school has a long and proud tradition. It was founded by the Carmelite order in 1811 but was not officially opened until 1814. At that time there were more than 100 boys attending the school. Now there are more than 350 children enrolled.
The school has 3 values which are core to our school. These are Respect, Kindness and Team-work. The practice of these values lies at the heart of St. Joseph’s, making it a friendly, caring and inclusive place to learn.
The current principal is Mr. Brian Coulston and our deputy principal is Ms. Anne Desmond.
The school excels in music, sport and science, providing opportunities for all children to discover and develop their talents. And if that’s not enough come and see our art work at Art for All week!
We are also a Green school with the pupils playing a very active role in looking after the school – planting flowers and shrubs and working in the school garden.
