During the day, Jo teaches AP Calculus and PreCalculus at Flintridge Preparatory School in La CaƱada, CA. But at night... he does like any exemplary teacher: grades tests, prepares lessons, records softball box scores, answers tech-related questions, and offers virtual tutoring through chat and social media.
It's a wonder how he had time for anything else! And, isn't that the case for most teachers!
Jo has been on the periphery of Hallpass and Friends since its founding and is now a lead on the Calculus Pivot project. His background in business marketing and logic has made him an valuable member of the Hallpass team.
