Benjamin Gryner, hypnosis practitionerHypnosis

About me and my approach

Understand what is keeping you stuck—without reducing you to the problem.

For more than 15 years, I have worked with people who want to change an automatic response, get past a block or feel freer in their own lives. My approach brings together Ericksonian hypnosis, careful listening, professional experience and methods I have developed through practice.

Sessions are currently offered in French only.

How I see it

Your unconscious mind is not trying to make your life difficult.

It often repeats a response that once made sense: protecting you, bringing relief, avoiding danger, maintaining control or preserving a balance. The problem begins when that response keeps running even though your life has changed.

My work is not about asking you to fight yourself. It is about understanding what the pattern is still trying to do, then making room for a response that fits your life now.

My background

A long-standing interest that grew into a carefully developed practice.

Technique matters. How it is used, explained and adapted to each person matters just as much.

01

Understanding the human mind

I began exploring self-hypnosis early on, first to improve the way I learned and then to observe how attention, mental imagery and automatic responses shape our experience.

02

An earlier career in healthcare

That experience taught me the importance of a clear framework, a genuine human connection and language people can understand—without turning a person into a problem to solve.

03

Training at ARCHE

I trained at the Académie de Recherche et Connaissances en Hypnose Ericksonienne, a school and research center founded in 2002 and now active in France and internationally.

More than 15 years refining my practice

I have worked with thousands of people, trained in NLP, perinatal hypnosis and focused change techniques, and continued to shape an approach that evolves through real-life practice.

The session

A direct, human and structured approach.

You do not have to fit into a ready-made method. The session is built around the way you think, feel and respond.

Listen

Start with your reality

Your words, your reactions and the specific situations in which the issue appears guide the work.

Understand

Make sense of it without getting trapped in analysis

Understanding what an automatic response is doing helps us work with it without requiring an endless review of your entire past.

Experience

Develop another response

Hypnosis engages attention, imagination and sensation so that change becomes more than a good idea.

Check

Bring the work back into real life

What matters is what changes in real life after the session.

Original methods

Two protocols that use time as a resource for change.

Promesse and TimeShift are two protocols I developed through my practice. They use imagination, memory and hypnotic projection to make change feel more tangible, without promising an automatic result.

A promise between the child you were and the adult you are today

The Promesse protocol

In the Promesse protocol, hypnosis takes you back to a meaningful moment from childhood. The child you were makes a promise to the adult you will become: when the time comes, you will be able to find the inner resources you need to move forward and get past what has been holding you back.

  1. Return to a meaningful moment in childhood.
  2. Make a promise to your future self.
  3. Reconnect in the present with the resources—and the permission—you need to move forward.

Explore a possible future to give the present a clearer direction

The TimeShift protocol

Within the hypnotic experience, TimeShift lets you move between the past, the present and a possible future. You explore what life could look like once the change has happened, then work backward toward the steps, choices and resources that can bring you closer to it. This is not about predicting the future. It is about giving it direction.

  1. Explore a future in which the goal has been reached.
  2. Connect that future with your story and your resources.
  3. Return to the present with a clearer path forward.

The book

Benjamin Gryner’s French-language book about the unconscious

Understand your unconscious mind.

I wrote this book to explain the mechanisms behind experiences we do not always understand: habits, blocks, learning, protection and change.

I devote an entire chapter to the Promesse protocol. The book also explains how I think about the unconscious—not as a mysterious force that controls you, but as a set of processes you can learn to recognize more clearly. The current edition is in French.

People also describe feeling heard, receiving clear explanations and experiencing a genuine human connection.

I waited three months before leaving a review because I wanted some perspective. In early January 2026, I decided to start the year by quitting smoking. After years of unsuccessful attempts, I went to Benjamin on someone’s recommendation, without really believing it would work. I left the session relaxed but still skeptical. I had taken a picture of my last cigarette before the appointment. It really was my last. Three months later, I still had not touched a cigarette—all after a single session. It was as though I had simply forgotten how to smoke. If I had known it could work this well, I would have done it much sooner. Thank you, Benjamin—you saved my lungs!

Benjamin, I truly wanted to thank you for today’s session. I arrived carrying a heavy mental load and a great deal of stress, and I already feel lighter, calmer and more hopeful. The way you listen, your kindness and your professionalism immediately create a sense of trust. You can feel how deeply committed you are to the people you work with, and that makes all the difference. Thank you for this valuable moment and for the care you bring to your work. I look forward to seeing the positive effects take hold over the coming days.

I knew nothing about hypnosis. This was my first experience, and it worked: after just one session, I stopped smoking completely. A huge thank-you!

I went in skeptical because I knew very little about hypnosis. I was pleasantly surprised. Benjamin explained hypnosis clearly; we talked at length and did exercises, and without realizing it, my unconscious mind was already at work. I left thinking we had “only” talked. Yet when I later faced the situation that had brought me to him, I felt no panic or anxiety. I wholeheartedly recommend the experience.

So kind and genuinely attentive. Thank you so, so much. One session was enough to help me take action and get past what had been holding me back. It completely changed my life.

It is amazing how much better I am sleeping. My children even noticed that I was much calmer, even though I had not told them anything.

Thank you, Mr. Gryner—you are amazing! Since our session on Monday, I have not had any episodes of disordered eating. I can also feel fullness again, which had not happened for a very long time. I am genuinely delighted with the result and wanted to share it with you. I started exercising again the very next morning. I even did a set of exercises—I could hardly believe it, and it almost made me laugh!

I did not believe it would work. I booked a session because I needed something faster than therapy: the repetitive thoughts and obsessive ideas had to stop. After my appointment with Benjamin, I began waking up without those thoughts clogging my mind. One week passed, then two. I am now starting the third week. It feels as though this is behind me.
