About

Get to know me — not through a résumé, but through who I really am.

Through 3 questions, I invite you to discover where I coach from.

Portrait of Nicolas Dalléry
01

Nicolas,
who are you?

I'm a father of three and someone who needs to feel the world in order to understand it.

An athlete, wingfoiling and ski touring taught me the body's capacity to sense every micro-vibration before the mind can even put it into words — an absolute presence in the moment. This connection to life flows through everything I am.

What people say about you & your promise?

« Unconventional, authentic, joyful. Touching yet powerful — like a good wine. »

A deep sensitivity that feeds strength, a mischievous intelligence paired with presence.

My promise is born from all of this — and from a certainty forged in the flesh.

An owl at the heart of the sun:

  • See clearly, even in the dark.
  • Watch over, with presence.

That's the spirit of Selformance.

February 2026 · Western Sahara

A sudden viral myocarditis struck me down. Far from everything. I owe my life only to my partner and to an improbable alignment of planets.

That event reminded me, with a luminous brutality, that every moment counts — and that every human being deserves to be accompanied with total presence.

That's where I coach from.

Robustness is born from an inner alignment, between what we think, what we feel, what we do. It's a way of being that I choose, every day.

That's Selformance: bringing everyone performance through our awareness.

Let's walk this path together.
