Dean Leak helps leaders and teams disagree well, so the best ideas make it into the room, not the corridor. Over 200 talks for Olympic teams, FTSE 100 companies, governments and global brands.

Most leaders tell me their teams argue too much. Then I sit in their meetings. Nobody argues at all. Everyone nods, the decision sails through, and the real conversation happens afterwards. In the corridor. On WhatsApp. In the meeting after the meeting.
I call it the Price of Peace: every unsaid doubt, unshared risk and swallowed idea quietly taxes your performance. Artificial harmony looks like alignment. It votes like alignment. It just doesn’t perform like alignment.
And to be fair to your people, they’re not being weak. They’re being kind. They’ve learnt that challenge can cost relationships, so they protect the relationship and quietly spend the performance.
Groupthink is an operational risk.
Dean reveals how healthy conflict and human connection transform workplace tension into a competitive advantage for leaders navigating constant change. Every talk is shaped around your audience, your goals and your language.

Healthy conflict is disagreement about ideas, decisions and the work, done with respect and in the room. It is how teams test their thinking, surface risks early and commit to decisions, without damaging trust.
