“Solved a 26 year old smoking addiction in 3 hours! . . . Can’t recommend him enough!” Raj, Cronulla (5 Star Google Review)


Seian is the Lead Therapist and owner of Quantum Hypnotherapy, the No. 1 choice in Sydney for Clinical Hypnotherapy and Rapid Resolution Therapy (RRT). And now available across Australia and internationally online. And he loves his work: “Watching someone’s life transform in front of your eyes – really, how can I call that work?”

He has trained extensively with the Australian Institute of Clinical Hypnotherapy (The Institute of Applied Psychology), The Center for Integrative Hypnosis (New York), The International Association of Generative Change (California), The Institute of Mind Science, The Institute of Human Technology, Rapid Resolution Therapy (RRT) with Dr Jon Connelly (Florida) , Beyond NLP, The Anglican Counselling Centre, and Uncommon Practitioners (U.K.). He is the ONLY Certified Advanced Practitioner of Mirroring Hands (the therapy developed over decades by the great Jungian therapist, Ernest Rossi), in Sydney. And he is one of the ONLY therapists in Sydney trained in both RRT for Trauma and the UK’s How To Stop Anyone Smoking System.

As well as seeing clients in his private practice, he worked alongside one of the Sutherland Shire’s most reputable and experienced GPs, Dr Valerie Parish, for 5 years.

Prior to becoming a therapist, he worked with teenagers and enjoyed a very successful and extensive career in the corporate world with Fairfax Media.

When he’s not in clinic, you can often find Seian tucked away in a local café in the area enjoying a coffee and writing, or down at the beach doing his best impression of surfing.

  • Hypnotherapy

    is a very gentle and creative process of helping you achieve a focussed state where you can absorb new ideas and elicit exciting changes in your life. You get to re-write and update any software that is simply of no use to you anymore. And you are always in control of the process.

  • Rapid Resolution Therapy (RRT)

    utilizes innovative concepts, multi-level communication and specialized tools to resolve emotional disturbance and maladaptive behaviour. RRT changes how the unconscious mind processes information so that improvements are natural.

  • Strategic Psychotherapy

    is a highly effective process of aiding you to identify and interrupt old patterns, see their mechanics, and easily make accelerated changes that neutralise what is not working and adopt new ways of interacting with your world. Strategic Psychotherapy works hand in glove with Hypnotherapy, amplifying your results.

  • NLP

    is Neuro Linguistic Psychology - The mind (neuro) regulates how our bodies function, language (linguistic) determines how we communicate with ourselves and other people, and our sub-conscious strategies (programming), determines the kinds of models of the world we create. NLP addresses change at these very core areas utilising safe and easy techniques for powerful, rapid change. And it’s fun!

Seian is highly skilled and my time with him has been transformative. I have always felt safe and comfortable, and he’s very easy to talk to. I would highly recommend sessions with Seian to help with any problem, or improve performance across all aspects of life. It’s one of the best investments I’ve made and I wish I’d found him years ago.

I have had incredible success after multiple sessions with Seian at Quantum Hypnotherapy. All sessions with Seian have left me feeling safe, comfortable, relaxed, calm and empowered.Seian is kind and professional. He remembers details from previous sessions and listens deeply to what you are saying and sharing, clarifying information along the way. It was so nice to feel understood and have my feelings validated and unpacked. Seian used a range of analogies to explain situations and emotional reactions. These were easy to understand and have really stuck with me, helping me in my day to day life.I highly recommend booking in to see Seian at Quantum Hypnotherapy.

I have recently had some sessions with Seian and he really understood me and the anxiety I have been suffering with. He was immediately engaged and there was a sense of deep connection to the issues I have been dealing with. Apart from the fact that he listens and explains things so well, Seian has the techniques and tools to really help to make a change to the entrenched patterns that can cause pain and suffering when we don’t address them.Thank you Seian for giving me the hope that things can be different and be better. I would recommend Seian absolutely.
