Matt Granoff
Language Arts Curriculum Developer
Matt majored in folklore and mythology at Harvard before slowly drifting into teaching English. This new field is unquestionably of more use to the world in general, but if you ever want to just talk about world mythology, he's pretty much always down for that. Matt started teaching rhetoric at a classical academy in Minnesota before moving to the Bay Area and teaching English, ethics and game design theory (three separate courses, sadly) at the Menlo School and English and philosophy at Saratoga. He's always found the most exciting part of teaching to be getting students to push beyond their intellectual comfort zones and see just how much cool stuff is out there in the world to learn about. When he's not teaching or taking care of his 3-year-old, Matt spends his time doing competitive trivia, puzzle hunts, computer gaming and reading lots of sci-fi and comics.
