The biggest opportunities are often hidden behind assumptions we've never thought to question.

Dennis brings this idea to life through extraordinary stories that entertain, challenge perspectives, and inspire audiences to see what's possible.

Signature Keynote

The Assumption Trap

What if the biggest thing holding us back isn't a lack of ideas, resources, or opportunities, but the assumptions we've never thought to question?

Every day, we make decisions based on what we believe to be true. But some of those beliefs are simply assumptions we've accepted without question. And over time, they can quietly limit our thinking, stifle innovation, and prevent us from seeing possibilities hiding in plain sight.

In The Assumption Trap, Dennis Geelen takes audiences on an entertaining, thought-provoking journey through extraordinary true stories, surprising twists, and remarkable examples of people who challenged conventional wisdom and discovered something extraordinary.

Along the way, audiences begin to recognize the hidden assumptions shaping their own decisions and discover how a simple shift in perspective can open the door to entirely new possibilities.

Audiences will walk away with:

A fresh awareness of how unquestioned assumptions can limit creativity, innovation, and opportunity.
A new perspective on the value of challenging conventional wisdom and asking better questions.
Practical ways to recognize and challenge assumptions in their work and everyday decisions.
The inspiration to look beyond "the way things have always been done" and explore possibilities others might overlook.
