About Dr Suzanne O’ Brien

Dr Suzanne O’ Brien is a neuroscientist and GHR-registered hypnotherapist, with doctoral and master’s training in neuroscience, and a undergraduate degree in psychology. Her research explored the brain’s ability to adapt and change in response to experience. This perspective underpins her work, whether she is delivering workshops or working one-to-one with clients.

Her research interests have also included women’s mental health and early childhood development. Suzanne previously served as Vice-President and board member of the Marcé Society (UK and Ireland), an organisation dedicated to supporting mental health during pregnancy and the postnatal period.

At the heart of her work is a simple aim: to translate complex neuroscience into grounded, practical insights that feel relevant to real life, and that people can actually use. Within hypnotherapy, this means working with the brain’s natural capacity for change, learning and emotional processing, creating a structured and collaborative space for meaningful change to occur.

Client Experiences

"I came to Suzanne with the aim of improving my confidence, I felt scared of being seen, I wanted to feel comfortable with public speaking and get over the feeling of imposter syndrome. For too long I had felt that I was unworthy of being seen, heard or deserving of the good things that had come my way. Even if I had worked hard and knew that I “know my stuff, I deserve to be in this room” I was constantly scared of being judged, thinking it was pure luck that I had gotten this far. I was scared to assert my authority in both my personal and professional life and I desperately wanted to get over these feelings. Under Suzanne’s care, gentle guidance and hypnotism practice I felt like a weight had been lifted off. That there was no need to second guess myself, I learned to trust myself, lean into my strengths and own my words. I now move and speak with confidence which comes from a place of deservingness. I feel stronger and have been able to speak from the heart, knowing and owning my worth. I no longer play small, but I still feel like me, nothing show-offish or obnoxious and I am so grateful for Suzanne’s work, guidance and support."

"I had the most life changing hypnotherapy session with Suzanne. I was struggling with boundary setting and always had really bad FOMO (fear of missing out) when going out with friends. .I would always stay out longer than I should or wanted, even if I had important things that I needed to be up for the next day, I just struggled so much with being able to say no or knowing when to call it a night. I've always been a bit sceptical if hypnotherapy could work for this sort of thing, but I gave it a go anyway and I cannot believe how much this has changed my entire life. Not only did it work within that same week, but it's been over a year now and I've still been able to go home when I want and to feel good doing it. All my friends noticed the change and couldn't believe it. I feel more motivated than ever, I've allowed myself to feel confident in setting boundaries and Suzanne has a way of saying things that stick with you and make you feel empowered. So I left her session feeling so positive and happy- that feeling has stuck with me to this day. Suzanne got me in such a deep state of hypnosis with her soft, calming voice and made me feel at ease straight away. Cannot recommend her enough. If you want to change your life you need to see Suzanne!”

“My clinical hypnotherapy session with Suzanne in preparation for my third labour was just magical. The relaxation and calmness I felt during and afterwards was exactly what I needed after an extremely stressful couple of months. Especially, as I had no real time to prep for the imminent labour otherwise. After the session, I had the best night sleep (hard to come by at 9 months pregnant) and the effects of this calmness carried over to the next day and to when the labour started two days later. Would highly recommend this to any mama to-be regardless what their birth preferences are.

"Hypnotherapy with Suzanne was such a special and grounding experience. She offers a unique space where you can go deep within, discover more about yourself, and feel truly seen, heard, and cared for. I highly recommend Suzanne"

— Oreke
“Suzanne helped me during a period of high stress and anxiety. I immediately felt safe and supported, and she made it easy for me to open up. Thanks to my work with Suzanne, I felt calmer and more able to handle the changes I was going through. I can’t recommend her enough.”

— R.
“I found my hypnotherapy session with Suzanne very relaxing and helpful. After carefully assessing my needs (troubled sleep/light sleeper and sense of overwhelm), she explained the process and built trust between us. The hypnotherapy itself was a great experience, first I felt very relaxed and afterwards I knew things were changing for the better! My sleep improved day by day and even if I wake up, I now manage to re-fall asleep. In general I feel more at peace and calm within. A massive thank you!”

— Daphne
"I came to Suzanne feeling stuck in a cycle of self-doubt and negative thinking that I just couldn't seem to shake on my own. From the moment the session began, I felt completely at ease. It was as if I was wrapped in my own personal bubble of calm, and bliss. The trance-like state was surprisingly natural, and somewhere within it something quietly shifted. I can't fully explain it, but my thinking around my own self-worth feels a little different now. If you're caught in your own head and struggling to believe in yourself, I'd wholeheartedly recommend giving Suzanne a try. Sometimes you just need a different kind of space to find a new perspective"
