A summer staple since the early 1980s, St. Mary's Cultural Festival is a two-day long food and music festival held in the parking lots of St. Mary's Church.

The origins of this festival are found in the former Cristo Salvador Church, where parishioners began this festival both to highlight the Hispanic Culture of the parish and to raise much-needed funds for the operations of the parish. Following the parish mergers of Cristo Salvador and St. Mary's in June of 1995, the Hispanic Festival moved to St. Mary's where the same great-tasting foods were served at a new location.  In 2013 the "Hispanic Festival" was renamed the "Cultural Festival" to further highlight the dynamic multicultural nature of St. Mary's Church.

The 2023 Cultural Festival will be held on June 16, from 5:00 - 9:00 pm. & June 17, from Noon - 9:00 pm.
