Lehigh Valley veteran actor Ralph Montesano recently faced one of life's most challenging roles. Recognized with wife, Vicki, as a mainstay couple of local community theater, in particular, Bethlehem's Pennsylvania Playhouse, Ralph's stage work came to a halt in April 2013 when he was diagnosed with stage 4 glioblastoma, or a malignant brain tumor. After undergoing 18 months of treatment that included trips to Duke University Medical Center in Durham, N.C., the news is now positive. On September 26, the Macungie couple once again will take the stage for the opening of Pennsylvania Playhouse's "I Love You, You're Perfect, Now Change." The musical production runs through Oct. 12.
