She was a trustee there as of her death, and she was a member of the Italian Sons and Daughters of America Lodge, Pittsburgh and the Columbiana Federation Lodge No. 23 in Arnold. Continuing her active life, Rosalie worked at the New Kensington-Aronld School District as an assistant for the Title I Reading Program in the Fourth Avenue school and H.D. Berkey buildings.
