What is Old Pueblo Playwrights? Old Pueblo Playwrights (OPP) is a non-profit organization dedicated to encouraging the creation of new dramatic works by Arizona authors. Its members are writers -- both professional and aspiring -- who meet weekly to hear readings of their works and to discuss those works critically. OPP membership is open to any interested writers of dramatic works for stage, film, radio, or television (as well as to any other artists in those disciplines).
