CRUSH SCHOOL

5644 1st Avenue South Minneapolis, MN, 55419

I blog on Brain-Based Learning, Metacognition, EdTech, and Social-Emotional Learning. I am the author of the Crush School Series of Books, which help students understand how their brains process information and learn. I also wrote The Power of Three: How to Simplify Your Life to Amplify Your Personal and Professional Success, but be warned that it's meant for adults who want to thrive and are comfortable with four letter words.
