Colombo OBA was started in 1935 by few old Aloysians living in Colombo. After several meetings the first AGM was held on 23 March 1935. Dr Marceline De Costa was elected as the first President. Well known Banker Mr N.U. Jayawardena and Mr P.D. Henry were elected as Secretary and Treasurer respectively. Dr Costa held the post of President till 1945 in which year he handed over the reins to Rev. Fr. Terrence De Silva S.J. We had a long list of distinguished old boy’s from all spheres of Professional and Business world as office bearers of our Association. Current President is Mr Suhail Junaid and Secretary is Mr Milinda Jayawardena.

Our Association continues to involve in projects to improve infrastructure of the College.
