The Old Trinitarians’ Union (OTU) provides a way for all ex-students of Trinity to maintain contact with their School.

As members of the OTU, Old Boys are able to keep in touch with their former classmates through class reunions and participation in spiritual, sporting, cultural and social activities at the School. They are kept informed with news of the School and other Old Boys through a monthly community eNews, and the bi-annual magazine, Trinity News.
