Some information about me…

I am an experienced QCH Practitioner and QCH Training Manager at the Quest Institute, Regents University in Central London, training new therapists to work worldwide.

Why did I decide to become a Cognitive Hypnotherapist?

I have always been interested in people and often found myself listening to the worries of friends and family, doing my best to help.Wanting to do more than just listen though – I decided that I wanted to give good, solid help that made a difference. To do this I needed to train to be a therapist.

It was also very important that I provide a modern, friendly and structured service where my clients felt safe and supported. Treating people with care, respect and kindness is my aim.

My own life changing experience of hypnotherapy came when I sought help for a fear that was beginning to really restrict my life. In one session my life was transformed. The strange thing is that I remember asking the therapist “Did you actually hypnotise me?? ” It didn’t feel weird or life changing – I just felt calm and relaxed. I couldn’t really believe how quickly and powerfully the therapy worked. It was as if the fear had never been there…

Where did I train?

I studied with the Quest Institute which is based at Regents University in London. This was because  I wanted to make sure that I studied Cognitive Hypnotherapy with a school that was credible, supportive and that gave me an in depth knowledge of my subject. The Quest Institute is internationally renowned with an ongoing research programme into its effectiveness with Anxiety and Depression.

Having researched courses extensively I chose to study with the founder of Cognitive Hypnotherapy and Wordweaving™,  Trevor Silvester

It is a decision that has quite simply changed my life and one that I am thankful for each day. The HPD Diploma course is an eleven month course with hands on practice as well as written examinations, including case studies. It is intensive and thorough. The Quest Institute is considered one of the premier schools for hypnotherapy in the country and  I have since gone on to become a Master Practitioner.

What are my qualifications?

  • Diploma in Cognitive Hypnotherapy (DipCHyp)
  • Hypnotherapy in Practice Diploma (HPD)
  • Neuro Linguistic Programming Master Practitioner Certificate

Professional Associations

I am a member of the CNHC (Complementary and Natural Healthcare Council)

This is the government regulated voluntary register for complementary therapists.


I am a member of the QCHPA 

The QCHPA is the professional association for the evidence based approach of Cognitive Hypnotherapy. Only therapists who have qualified at the Quest Institute can belong to this organisation. We follow a structured yet gentle approach where the client’s needs are what count. The Quest Institute has been running a research study for the last 5 years. This study has recently been published in the Mental Health Review Journal and has shown very positive results. The study continues because the QCHPA takes the treatment of mental health very seriously and we want to have evidence to prove how effective the Cognitive Hypnotherapy approach is.


I follow the strict Codes of Conduct of these organisations and in order to be a member I have to renew each year with proof of CPD. I am proud to be able to say that I belong to these organisations and adhere to the high standards that they require.

Insurance and DBS Check

I am fully insured by Holistic Insurance and I hold an enhanced DBS certificate.
