Sierra Boggess

theINTERVAL: When we met Sierra Boggess on a rainy New York City morning, within five minutes it became clear that she’s a woman who has given a lot of thought about who she is and how she wants to be in the world (she even managed to do this during the now standard, “It’s nice that it’s not freezing out, but also it’s kind of creepy,” small talk). Sierra is currently starring as Rosalie Mullins, the principal in School of Rock.
