St. Catharine of Siena is a Roman Catholic Church nestled in the West Side of Cincinnati. Built in 1903, we are a parish rich in history, unique beauty, and vibrant in community. We are one of four other Family of Parishes that make up the Family of the Most Holy Eucharist - Our Lady of Lourdes, St. Aloysius Gonzaga, St. Antoninus, and St. Martin of Tours.
