Matt Granoff

Matt Granoff Senior 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.

Stephanie has been working with AoPS students since 2017 and was previously an Associate Director at AoPS Academy Bellevue. Stephanie has always had a deep interest in understanding how the world works. This led to the decision to major in mathematics and physics at Washington State University and led to tutoring others in math and science classes while in school. She quickly realized how much fun it is to help people explore new and difficult concepts by challenging them to think through their own ideas. She then spent two years as a graduate student in mathematics at the University of Colorado, where being a TA who taught Calculus was the most rewarding part. Next steps included teaching students of all ages and ability levels, including teaching high school math and science for three years. Stephanie loves working with students who are excited about math, helping them rise to new challenges and discover new problem-solving strategies, but also loves working with those who aren't as excited about math, helping them to see how fun and rewarding it can be. When not talking about math, Stephanie enjoys traveling, hiking, and making crochet hats.

Our family regularly talks about AoPS. We try to think about how our life would be different without you all. What if my daughter hadn't learned to love math? What if she never experienced being pushed to her limits? Overcoming failure? She wouldn't be who she is. And she is AWESOME! A very proud mom here. We are so fortunate that we found AoPS Academy. I credit AoPS for much of her confidence.
