The SLOBA Aloysian Fellowship was founded in 2008, following the successful performance of the Head Boys’ Choir in the 80th Anniversary Variety Show, which consisted of former Head Boys or their delegates from each year since 1962, who have a special affection for and devotion to our alma mater.

The Fellowship hosted a dinner gathering on 10 Jan 2026 (Sat) at the Hong Kong Chiu Chow Chamber of Commerce Clubhouse in Sai Ying Pun. During the event, the Fellowship passed an amendment to its Terms of Reference, expanding the membership quota to two graduates per year.

The current Head Boy in the school, Alvis Chan, also introduced the ongoing works of the Prefects’ Association. SLOBA President, Aaron Lee (1994), shared the latest progress of the centenary fundraising, and called for support from Fellows to engage their classes in the campaign.

聖類斯舊生會學長團於2008年成立，緣於母校八十周年文藝匯演中的總學長合唱團演出，聚集了由1962年以來的歷任總學長（學生代表）。

學長團剛於2026年1月10日（六）在香港潮州商會會員俱樂部舉辦了一次晚餐聚會。當晚學長團通過了其會章修訂，將會員人數配額擴大至每屆兩位代表。

現任學生代表陳鋮睿（Alvis Chan）亦介紹了母校學長聯會的最新工作；舊生會會長李龍基（Aaron Lee）分享了一百年籌款活動的最新進展，並呼籲各位成員支持並鼓勵他們的同屆同學參與。
