St. Pius V is a Roman Catholic faith community following the teachings of Jesus Christ. As a united parish, we celebrate and evangelize our many cultural traditions through liturgy, prayer and service. Empowered and challenged by the Holy Spirit, we welcome all in fellowship by sharing our gifts and reflecting God’s love.
