Mark Schaefer Keynote Speaker, Consultant, Bestselling Author of "Known"
"I knew we were in for some great instruction but in the course of his visit, Mark transcended the promise of being an effective teacher. An hour dissolved into an instant. But even more remarkably, he generated a ‘majestic synergy' from the encounter – an elixir of wisdom, passion, laughter, and the power of human connection. You could say he left an enduring mark."
