Who is Peter F. Gallagher?

For the last 35 years he has worked in over 35 countries for some of the world’s most successful organisations

Peter F. Gallagher is a Top 7 Global Leadership Authority, the world’s #1 ranked Change Leadership Thought Leader, and a 15-time author who advises boards and C‑suites worldwide. He is recognised internationally for advancing the Leadership of Change® and, now, AI‑OCM Leadership — the discipline that helps leaders navigate the AI wow, the AI oh no, and the disciplined AI how that delivers responsible, measurable transformation.

Peter’s leadership philosophy is simple yet provocative: Change waits for no leader. All leadership is about change and improvement — and if you are not leading these, you are managing. His mission is to redefine leadership as the act of influencing people through vision to embrace change and deliver continuous improvement, a human responsibility rooted in our evolutionary drive to adapt. Leadership, in Peter’s view, is the human expression of our evolutionary arc — a force that shapes possibility rather than preserves comfort.

Peter works with boards, CEOs, and senior leadership teams to prepare and align them to effectively and proactively lead their organisations through change and transformation.

Why does organisational change and transformation constantly fail?

Do you ensure your leadership team knows their three change responsibilities?

Do you have a change sponsor who will keep the leadership team aligned?

“Change waits for no leader. The capabilities that sustain daily operations are not the same as those required to lead change — especially in an AI‑accelerated world.”

Peter F. Gallagher is a leadership guru, change management global thought leader, organisational change authority, international corporate conference speaker, 15X author, and C-level change leadership coach.
