I am an experienced business professional with experience in DEIB (Diversity, Equity, Inclusion, and Belonging), Sales, Project Management, New Product Development, Supply Chain, and Planning, as well as a former math teacher (2016-2019), a long-time Khan Academy user (profile name Dayvyd), a Khan Academy Ambassador (2019-2023), and an avid lifelong learner. Some of my certifications include: Master of Education in Math Instruction; Project Management Professional (PMP); Harvard Business School Credential of Readiness (CORe); and Texas certified math teacher, grades 4-12 (roughly arithmetic, algebra, geometry, trigonometry, statistics, and calculus). I am excited to help in any way I can with this great project to help learners around the world! Look forward to working with y'all =)

Awesome session thank you for hosting! I believe this was my first session with you, but I’ll be sure to attend more in the future. It was nice to see someone with diverse content on schoolhouse! You also taught a lot and explained things very well

David really helps you reach outside of your comfort zone but not in a forceful way. He does it in a way where it's healthy and does an amazing job in creating a safe environment for all learners.
