My favorite part: her personal hype man! @ryanflessner

[Courtney Flessner @CFless]

Still telling these stories today. Literally. I was actually working with teachers today about dispositions towards teaching mathematics. We have a lot of work to do in our schools to change the narrative around math! I’m here for it.
