Upper St. Clair alum’s showbiz career spans from ‘Last House’ to The Comedy Store

After graduating from Upper St. Clair High School in 1967, Sheffler wouldn’t just find himself in the entertainment industry, but also in one of the most infamous exploitation horror films of all time, “The Last House on the Left.”
