Class of 1980
Class of 2012
The Holy Trinity Diocesan alumni site is made so that students and teachers from the Hicksville high school can reconnect with those that they met while attending high school. If you are a Holy Trinity Diocesan alumn, we encourage you to register and be sure to sign up for the alumni newsletter. We also encourage you to keep up to date on news and reconnect with lost friends.
