About David

David Penglase is a behavioural scientist, best-selling author, and Hall of Fame keynote speaker — one of Australia's most booked and rebooked conference speakers on the subject of sales success. Inducted into Australia's Professional Speakers Hall of Fame, he holds degrees in Business and the Psychology of Adult Learning, an MBA, a Master Degree in Professional Ethics, and a Master of Science in Applied Positive Psychology. His presentations combine evidence-based strategies with high energy and genuine entertainment, shifting mindsets and changing behaviours in ways that produce measurable results.

What sets David apart is the rigour behind the content. Over more than two decades of conference speaking, he has built a body of research focused on one central idea: that trust is the fastest accelerator of sales, leadership and customer service performance. His two books — The Art & Science of Building Customer Trust and LIVING in the Light of Day — distil that research into practical frameworks. He travels nationally and internationally, working with top-tier corporations and associations, and tailors every engagement to the specific brief of the client.

David is the right choice for sales conferences, national roadshows, franchise events, leadership forums, and any gathering where an organisation needs to move people from knowing what to do to actually doing it. Clients include major financial institutions, property networks, and industry associations. Repeat bookings are a consistent feature of his track record — a reliable signal that his content lands and sticks.
