Mark Berry is a leadership veteran with over 25 years of real-world experience guiding teams in high-pressure industries-including gas and oil, defense contracting, rail, and steel. He's led through chaos, rebuilds, deadlines, and breakdowns-and what he's learned doesn't come from theory. It comes from doing the work. Make no mistake-he's been to his fair share of leadership classes, corporate retreats, and professional development seminars. And while the frameworks sound great in a quiet room, most of them fall apart the moment you step back into the real world. That's the gap Mark set out to close-where systems meet execution, where pressure hits people, and where leadership actually has to work. His first book, Headspace: Surviving the Noise, tackled the internal side of leadership-clarity, resilience, burnout, and the battle between intention and distraction. Leadership and the Lion picks up where that left off, turning the focus outward toward team culture, accountability, and building environments people choose to be part of-not out of pressure, but pride. Mark writes the way he leads: with clarity, honesty, and zero fluff. His work challenges leadership myths, exposes the cost of control, and helps leaders build something that lasts-something that holds.
