Peter F. Gallagher Appointed Thinkers360 Ambassador for Change Management (2025–2026)

Honoured to Be Appointed Thinkers360 Ambassador for Change Management

I’m humbled to share that I have been appointed as a Thinkers360 Ambassador for Change Management for the 2025–2026 period.

Thinkers360 Ambassadors are selected based on global influence, original thought leadership, and sustained impact across both professional and digital platforms. I’m honoured to be recognised among this group of respected peers and contributors to our field.

As many of you know, my work is grounded in the belief that:

Change leadership inspires, change management organises and employee adoption sustains.

As an Ambassador, I will continue to:

• Champion the importance of change leadership over passive change management,

• Contribute to the elevation of standards across the profession, and

• Advocate for integrity, structure, and sustained adoption as core pillars of successful change.

With more than 15 published works, including the a2B Change Management Framework® and the Change Leadership Trinity, I remain committed to equipping organisations and leaders to drive transformation with purpose and discipline.

Congratulations to my fellow 2025 Ambassadors—I look forward to engaging with you all throughout the year.
