Founded in 1962 as the first Roman Catholic parish in Santee, Guardian Angels Catholic Church on Dalehurst Road celebrated its Diamond Jubilee in 2022, marking sixty years of continuous service within the Diocese of San Diego under the Roman-Latin rite. The parish operates the Cunnane Parish Center alongside a preschool and Vacation Bible Camp serving pre-kindergarten through fifth grade, anchoring an educational corridor that includes Carlton Oaks School on Wethersfield Road in the adjacent Carlton Hills neighborhood. Active ministries span the Prayers & Squares quilting outreach, the Filii Mariae devotional society, and an annual Fall Festival that draws attendees from across East County San Diego. The church's location on Dalehurst Road near Fanita Parkway and Settle Road places it within walking distance of the Santee Lakes Campground, the 190-acre recreation preserve that anchors the Carlton Hills district. The parish sanctuary and parish center together occupy a dedicated campus with a secured coded-entry system for parish offices and classroom wings.
