Holy Trinity runs a Sunday School program from September through May. Children range in age from 3 to 12 and are usually divided into three groups: Pre-K/K, 1st- 4th grades, and 5th-7th grades. Classes meet during coffee hour in the church hall. The different themes covered include Old and New Testament, The Saints, The Divine Liturgy, The Feasts of the Church, as well as other topics of interest. The Church School also sponsors at least 3 charity events a year and puts on a play/performance once a year. A small teen group also gathers on a less formal basis. All interested families are welcome to attend!
