Growing up in Stoneham, Massachusetts, Corsaro began showing interest in drawing at age 3 while attending St. John’s Preparatory School in Danvers, MA.,[2] and continued to pursue this passion throughout his adolescence. His father, Mario, owned a shoe store in the North End. Like his show's protagonist, Corsaro often performed downhill stunts via skateboards, bikes, and toboggans. However, a leg injury from one bike trick required him to be hospitalized at Lahey Hospital.
