Peter F Gallagher | Global Leadership Authority | Change Leadership Thought Leader |

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 a leading global voice on AI‑OCLeadership, helping leaders move through the AI wow, the AI oh no, and into the disciplined AI how that drives responsible, measurable transformation.

His 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. Leadership, for Peter, is the human expression of our evolutionary arc: a force that shapes possibility rather than preserves comfort.

His three core AI‑OCLeadership keynotes focus on the three change leadership responsibilities, leadership alignment, and the ten essential change management lessons every leader must know.

He is the author of 15 change management books

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.
All leadership is about change and improvement.
If you are not leading these, you are a manager!"
