About
Marc Devillard —
a life of learning,
questioning, helping others grow
Engineer, strategist, business leader for thirty years — and certified hypnotherapist. What may seem like a contradiction is in fact a deep coherence: my whole life, I have sought to understand how human beings work, and how to help them give the best of themselves.
The path travelled
A journey
that always leads toward others
Childhood &
adolescence
A nomadic childhood, a curiosity born early
Paris, Netherlands, Belgium, Provence, the Alps, Lyon… Growing up across several countries and regions, cultures and languages forges an adaptability and openness to the world that never leaves you. From an early age, I was fascinated by people — by what makes them work, what blocks them, what makes them flourish.
Scientific
training
Rigour as a foundation
Trained in the French grandes écoles, in scientific disciplines and business administration. Engineering training did not only teach me to calculate — it taught me to think, to model complexity, to find the essential in the noise. These are skills I use in every session today.
30 years of
career
Consulting, strategy, business leadership
Pipeline construction, strategy and organizational consulting, technology innovation, software, venture capital, entrepreneurship, video games — a versatile, demanding and international career that exposed me to thousands of people at pivotal moments in their professional lives. I learned to see people as better than they see themselves. I was told that often. I never knew if it was a compliment or a reproach — it is simply what I see.
Montreal,
today
IFHEC — and the discovery of a calling
It was curiosity that led me to enroll in IFHEC’s introductory hypnosis course. I wanted to understand, not to believe. What I discovered there exceeded all my expectations — not only the rigour and coherence of the method, but the human quality of Shaïda and her teachers, the values that underpin this teaching, and the profound kindness with which this practice is transmitted. I did not hesitate long before continuing.
My deep conviction
Every person carries within them
all the resources they need
My role is not to heal you — it is to guide you toward what you already know, deep down.
I have been through very hard times in my life. Periods when everything seemed blocked, when resources seemed impossible to find. And each time, I found within myself what was needed to come through — not alone, but by reaching for what was already there.
This personal experience deeply informs my practice. I do not come as a saviour. I come as a guide, convinced that you already know, somewhere, what you need — and that our work together consists of clearing the path that leads there.
Rigour in service of gentleness
Transformative hypnosis is a serious, scientifically documented method. There is nothing mystical about it — and yet it reaches what rational approaches do not always access.
Absolute respect for the person
You remain in charge of yourself at every moment. My work is never to influence you — it is to help you hear yourself.
Adaptability as a principle
Every person is unique. Every session is built for you, not for a protocol. Thirty years of adapting to very different people taught me to meet each one where they are.
Trust as a foundation
Nothing is possible without it. I work to earn it in every session — not by convincing you, but by allowing you to see for yourself.
What makes this practice distinctive
A rare
combination.
An intact scientific curiosity
Trained in the French grandes écoles and at INSEAD, I understand the mechanisms of hypnosis and can explain them to you clearly. Rigour does not exclude depth — it strengthens it.
Bilingual, naturally
French and English on perfectly equal footing — not a translation, a native thought in both languages. Sessions take place in whichever language you feel most yourself.
A deep and natural empathy
A particular sensitivity to the inner state of people — developed over a lifetime of listening, questioning, sensing what others are going through. It informs every session.
Real-world experience
Thirty years of exposure to professional challenges, crises, and difficult life transitions. I understand what you are going through — not through books, but through direct experience.
A rigorous and safe framework
Certified training at IFHEC, complete client files, absolute confidentiality, structured approach. You are in good hands — you will know it from the very first session.
For adults and for children
Transformative hypnosis adapts remarkably well to children and teenagers. I welcome both with the same care — and often, working with a child transforms the whole family.
The first session is already a first step.
No need to be convinced in advance. No need to have figured everything out. All you need is to show up, and let curiosity do the rest.
Transformative hypnosis is a wellness practice. It does not constitute a medical or psychotherapeutic act, does not establish any diagnosis, and does not replace medical or psychological follow-up.
