Chan Sui Ki (La Salle) College celebrated its 55th anniversary on 3 March 2025 with a Thanksgiving Mass presided over by Father Bosco, a former English and Religious Studies teacher at CSK and an Old boy of St. Joseph's College.

His touching homily reminded the congregation about the importance of gratitude—appreciating the people and blessings in our lives. Following the Mass, Father Bosco conducted a consecration ceremony for the newly renovated O'Brien Gymnasium.

The event brought together Brothers, current students, staff, old boys, and distinguished guests who reflected on the school's journey since 1969 and its commitment to the anniversary theme: "Embrace New Heights, Empower Great Minds."
