In 1920 the church obtained three bells named St. Stanislaus Kostka, Holy Angels and Our Lady Queen of Poland. The new main altar was installed in 1942 and restored in 2020. In the 1950s the works included the new painting decoration made by the artist Józef C. Mazur from Buffalo (1897-1970), a stained-glass maker, painter and sculptor originating from Galicia. He was educated in the USA at the Albright Art School in Buffalo and at the Art Students League of New York. He was the creator of the painting decoration of the Church of St. Stanislaus in Buffalo and many other projects, and some of his works are housed in the Polish Room at the University of Buffalo.
