Jennifer Diaz, 34, “has made history, becoming the first female head carpenter of Local 1 of the International Alliance of Theatrical Stage Employees. The local’s 3,351 members work in spaces from the Met to Carnegie Hall, at Radio City Music Hall and Madison Square Garden, and in every Broadway theater – including the Walter Kerr, which is where she was one morning in September, overseeing the load-in for the musical Falsettos.”
