A founding member of the company, he was principal actor in eight shows, for which he created ten characters and reprised the role of Santa Claus a couple of times, once in a new show, once in a revival. He also played Vinnie in most revival performances of "Speakeasy" and Primo Donna in the revival of "Variety."

At one time, he was the funniest man performing in restaurants, but his duties a musical director at a famous private school in Wheeling, have kept him from appearing in Mystery Theatre Shows regularly since 1998. In earlier days, Frank appeared in many of the Music Hall Players productions.
