It all adds up in Proof, the Pulitzer Prize-winning play that blends family drama, romantic tension, and intellectual mystery. This modern classic follows Catherine, a woman grappling with the legacy of her father’s mathematical brilliance and mental decline. Directed by Artistic Director Brendan Burke (who calls it his favorite play) the production features a cast that includes Shadowland regulars Eilis Cahill and Steve Brady, alongside TV talents Rudy Galvan and Carolyn Holding.
