Hi, I’m a community college math professor, David Hasson, and it is my pleasure to welcome you to my website. Born and raised in Sonoma County, I attended Santa Rosa Junior College and then transferred to Sonoma State University where I majored in Pure Math. While my original goal was to become an Astrophysicist / Science Writer, I caught the teaching bug at San Francisco State University when working on my Master's degree. I've been focused on Math Education ever since.
