About Your Professors

Joe Sadow holds a masters degree in computational and applied mathematics from Arizona State University, having focused research on numerical approaches to solve inverse problems. After teaching at local community colleges for a year or so, Joe was fortunate enough to start a career in 2019 as an actuarial analyst working on various aspects of California's Medicaid program. Love of teaching and interacting with students has compelled Joe to continue to moonlight teaching college math courses since starting graduate school in 2015. Fortune struck again when Joe partnered with ACTEX in 2021 to help create actuarial exam study materials. During time off, Joe enjoys learning chess, French, and testing out ideas for math videos on his wife, Allison and corgi-chihuahua mix, Clive.
