You deserve more—more joy, more freedom, more control. If you’re ready for profound breakthroughs, let’s work together to make it happen.

Living with IBS can mean constant bloating, discomfort, and anxiety about where the nearest toilet is. Hypnotherapy can help you calm the gut–brain connection so your body feels more relaxed and under control.
Addictive patterns can leave you feeling stuck, ashamed, or out of control. With hypnotherapy, we work directly with the subconscious mind to reduce cravings, change habit,s and support your wider recovery.
Anxiety can show up as racing thoughts, a tight chest, or a constant sense of dread. Hypnotherapy helps your nervous system settle, so you can feel calmer, safer and more present in daily life.
Old experiences can keep replaying in the mind and body, making it hard to feel safe, worthy, or hopeful about the future. Trauma-focused hypnotherapy offers a gentle way to process past events and reconnect with a stronger, more grounded version of yourself.
When sleep is broken or shallow, everything feels harder. Hypnotherapy can help retrain your mind and body to switch off at night, so deep, restorative sleep becomes more natural again.
Depression can make life feel flat, heavy and hopeless. Together, we use hypnotherapy to gently shift unhelpful patterns, reconnect you with motivation, and make space for more lightness and meaning.
Most diets work in the short term but not in the long term because they do not address the emotional and subconscious drivers of eating. Hypnotherapy helps you change your relationship with food and your body, so healthy choices feel more natural and sustainable.
Confidence Hypnotherapy
Self-doubt, overthinking, and fear of judgment can quietly limit your life. Confidence hypnotherapy helps you rewire old beliefs, so you can speak up, show up, and trust yourself more fully.
Stopping smoking is not just about willpower; it is about changing the unconscious associations that keep the habit in place. Hypnotherapy can support you to break free from cigarettes and feel more in control of your health.

I offer in-person hypnotherapy sessions at Islington Therapy House in central London. The rooms are calm, comfortable, and designed to help you relax as soon as you arrive. The practice is just a 5‑minute walk from Angel Underground station, making it easy to reach from across London.
Can’t make it to London? Remote hypnotherapy via Zoom or Skype allows clients from across the UK and abroad (US, Australia, and Canada) to benefit from my hypnotherapy approach.
Relax in the comfort of your home
Secure, private sessions
Full support and guidance for lasting results

I had a hypnotherapy session with Antonios Koletsas for my IBS and it was life-changing. Antonios was warm, and welcoming, and listened to my concerns. During the session, he guided me into a state of relaxation and used visualization techniques to help me heal. After the session, I noticed a significant improvement in my symptoms and felt a weight lifted off my shoulders. I highly recommend Antonios to anyone struggling with digestive issues.
My experience with Antonios has been very positive. I was diagnosed with IBS a few years ago and despite all my efforts with diet, and visiting several different specialists I couldn’t get to the root of my problem. Antonios approach was very unique, within 3 hypnotherapy sessions I could feel that almost all my symptoms have been diminished. I truly think hypnotherapy really helped me to establish a mind-body connection that wasn’t there for many years. Antonios helped me understand my triggers and also offered some dietary advice that I felt was really helpful. I certainly recommend Antonios services without hesitation to anyone.
Antonios is a great hypnotherapist! His calming personality creates a safe place for discussion and self-improvement! I had IBS for several years and Antonios has helped me tremendously! Highly recommend his services!
A core part of hypnotherapy is being able to feel safe and comfortable. Antonios goes a long way to make sure that you do, long before the session starts. He is a great listener, and would gladly answer any questions and concerns you had going in. Antonios clearly lays out what to expect during the session and creates a calm and relaxing atmosphere to help you enter the desired headspace. Though I’ve only had one session so far, I can highly recommend Antonios thanks to his patient and understanding demeanor. I am confident to recommend his services.
I visited Antonios because I was having some anxiety and sleep issues. I found him very professional and his voice was very calming. We had 3 sessions and that was all I needed. My anxiety is non-existent and my sleep has improved dramatically. Thank you
Was referred to Antonios by a friend and am very grateful for that. Our sessions have always been a very pleasant experience. Antonios is very professional and with attention to detail.
I recommend Antonios services without hesitation.
Antonios is really great at what he does!
The best thing about him is that he isn’t pointing in any direction. He is there listening with caution, observing and making me the right questions in order to find out and discover more things about myself and my personality.
Then from that point, I was feeling more and more confident to make changes and take decisions that really improved my life and my mindset. Thank you for that Antonios.
It was very interested throughout the session, the coach had my full attention and interest. Very clever and mindful questions at the right time. Overall I felt motivated, like a weight came off my shoulders, like my mind was in place and not as chaotic as before the session. I learned how to set goals and try and find tangible solutions. I also recommended this experience to my friends
I learned how to set personal goals. To be more specific, through this session I was given the opportunity to identify and re-evaluate several aspects of my life. In addition, I perceived our meaningful conversation as a challenging interaction between me and my life coach who taught me ways to fulfill my potential by setting realistic objectives in the short term in regards to my emotional and spiritual wellbeing. It was an interesting and exciting process that provided me valuable insights about myself and helped me to overcome barriers
Antonios positively contributed to my resolutions of both actively start my practice for future job interviews, and studying to acquire my professional license to become a registered pharmacist.
To be honest with you, before the session I wasn’t sure if life coaching works. But the session made me change my mind! Through the talk with Antonios, I managed to make a list and some commitments, as well as assess more options in my life.
