Today’s guest has spent more than 25 years focused on one big idea, helping learning truly stick. Dr William DeJean is the founder and CEO of Unleash Learning, working with schools and organisations around the world to build professional learning that lasts. His journey began in San Diego, where he taught high school for a decade and was named the 2003 San Diego County Teacher of the Year. He went on to complete a masters and doctorate in education, lectured in universities across the US and Australia and supported leadership teams through major change. His work brings together deep research, real classroom insight and a clear understanding of what makes learning meaningful and sustainable. William now leads Unleash Learning, hosts Unleash Learning TV and the Unleash Learning podcast, and presents at events including TEDx, Young Minds and Happiness and Its Causes. You can learn more about him on the Unleash Learning founder page. This is the second time I’ve had the chance to speak with him, and it’s a real pleasure to welcome him back. Let’s dive in.
