The parish reports about 1,600 households and lists ministries ranging from liturgical roles such as lectors, altar servers, and ushers to a food bank. Formation programs include Becoming Catholic (OCIA), a returning-Catholic track, religious education for grades 2 through 5, junior high and high school formation, and Catechesis of the Good Shepherd. Parish schools listed include St. Joseph's Catholic School, Bishop Kelly High School, and a Catholic Montessori. Separate children's services are not offered because families are encouraged to attend Mass together. Four parking lots serve the campus, and street parking is usually available nearby. Clothing should be modest and respectful, and self-guided tour hours and Sunday afternoon docent tours are posted.
