Tess Keijzer.
More heart
into this world.

That is my mission. Not as a beautiful message. As my life. Everything I do, coach, train and write starts from that one conviction: the world needs leaders who lead from the heart.

The mission

Bring more heart
into this world.

This is not a tagline I once came up with. It is the conclusion I drew after everything I have experienced, learned and lived through. After more than 25 years of exploring psychology. After 15 years as a coach, trainer and facilitator. After an accident that changed everything.

The world has enough smart people. Enough strategies. Enough models and frameworks. What is missing is the heart. Presence. Courage. The ability to lead from who you truly are, instead of from the expectations placed upon you.

That is what I facilitate in others. And it is what I practise daily myself, in my own life, my own leadership, my own vulnerability.

"You can only facilitate what you embody yourself. That is not a beautiful quote. It is the foundation of everything."

Tess Keijzer
The story

The moment that
changed everything.

In 2018, I had a mountainbike accident. I flew over the handlebars and landed hard. In the days that followed, while my body slowly recovered, something else in me suddenly became very clear: I had waited long enough. To live fully. To feel fully. To live the mission I had carried within me for so long but had never quite dared to live.

That accident gave me something back. Not the fear of vulnerability, but the courage to move through it. The realisation that the body always knows what the head sometimes prefers not to see. And the longing to pass that knowledge on to everyone I guide.

But let me be honest: the story didn't begin in 2018. It began much earlier.

As a young girl, I lived with my parents and sister in West Africa for several years. A different world. A different way of being. A childhood in motion followed. After my Masters in Psychology at the University of Amsterdam, I spent my twenties living in New York City and Sydney. In my thirties, I built my career from Amsterdam. I now live with my partner and daughter in Dubai.

Each of those places taught me something. About adapting without losing yourself. About being at home within yourself, wherever you are. About the power of presence in a world that is always in motion.

Over the past 15 years, I have guided more than 1,000 leaders in renowned organisations across finance, telecom, technology, retail, healthcare and government. I have seen what happens when people lead only from their heads. The exhaustion. The loneliness. The feeling that success doesn't truly fulfil. And I have seen what changes when they take the step towards the heart.

That is why I do what I do. Not as theory. As a conviction I live every day.

How I work

Science.
Heart. Presence.

I don't work with one method or one framework. I work with what is there. With who you are. With what is alive. And with the scientific knowledge of the heart, the brain and the unconscious that I have built over the years.

Heart Leadership
From 2018 onwards, I immersed myself in neuroscience and the science of heart intelligence. From that, the Heart Leadership Model was born: a scientifically grounded and fully embodied way of coaching, leading and living.
Hypnosis and the unconscious
I am certified in hypnosis and trained and certified as an RTT Practitioner. This allows me to work with the deeper, unconscious layer that conversation alone cannot always fully reach. Here, patterns become visible that often guide people more powerfully than they consciously realise.
Presence as an instrument
I bring deep professional craft to what I do. I am also fully present in who I am. Participants and clients feel the difference. My presence is not a technique. It is who I have become through everything I have walked through.
The book
In 2024, my book "Moedig Leiden vanuit je Hart" was published, named a must-read by Dutch Vogue. It captures the vision and science that form the foundation of everything I do. Currently available in Dutch.
