The annual Greek Fest is the Church's major fundraiser. Bringing the community together to help raise funds to sustain the fiscal needs of the parish and to introduce the surrounding neighborhood community to Sts. Constantine and Helen Church are the main objectives.

The entire parish community is relied on heavily to prepare, work and participate in the festival activities. There are also volunteer opportunities for students needing community service hours. The fellowship and resulting friendships are a wonderful extra benefit of working on this good cause. ​
