Let’s work together to bring you more happiness, calm and fulfilment.

How many sessions will I need?

Sessions are normally once a week and last 50 minutes. Please let me know if you would prefer a different structure. You can work session by session though booking a block of for or six sessions is more cost effective.  

The many clients will have between four and 12 sessions. Some have fewer and some will have more. Not all challenges are the same and no two clients are the same either. For example, some phobias may need just one session, whilst other phobias many require more. Addictions such as reducing drug dependency or overeating will normally require at least three or four sessions. 

My standard smoking cessation programme (as outlined here) is fixed at two sessions. 

I advise perspective clients to book a session and then book session by session. However there are reductions for block bookings.

How much do sessions cost?

I offer you a free initial consultation, by phone, under no obligation. All session prices include free support by email between sessions. I work in London’s Harley Street Medical district. 


Clinical Hypnotherapy: £115

Book four sessions: £395

Book six sessions: £595

What is hypnotherapy and is it safe?

Hypnotherapy (sometimes called hypnosis) is not only perfectly safe, you will find it relaxing and calming. You will hear everything said and sometimes may be asked to respond to questions as well. Unlike stage hypnotism shows, which are about entertainment, during clinical hypnotherapy you are in complete control and able to open your eyes if you wish to. 

It is rare to find someone who can’t be hypnotised. Have you ever daydreamed or concentrated on a book or TV show? Those are experiences very similar to the hypnosis trance state. Your mind was focussed and open and receptive to the information you were taking in. Hypnotherapy is simply when a trained and qualified expert guides you gently into that feeling of calm relaxation. Hypnotherapy involves structured visualisations or speaking to you whilst in this peaceful state. It is amazing how effective hypnotherapy can be.

What if I don’t want hypnotherapy?

With all clients I use a range of therapy techniques. These may include Mindfulness based tools which aim to train the mind to let go of past and future worries and concerns. I use NLP (Neuro-linguistic programming) and aspects of Cognitive Behavioural Therapy to challenge and change rigid or unhelpful thought patterns and beliefs. This means that some sessions may not have any hypnotherapy component. You can request that I primarily use one technique. 

For some challenges such as pain control, smoking or phobias, primarily I will use hypnotherapy. However I will always make use of other therapy exercises and techniques to ensure you see long lasting real results. No question or concern is too small, so please ask more about how I work.

Do you guarantee success?

Don’t believe any therapist who tells you they can 100% guarantee success. All therapeutic work is really a partnership between me, the therapist, and you, the client. I give you tools and work very hard to help you see things differently and gain resources. However whatever changes you wish to see will ultimately be carried out by you. You are responsible for your decisions, choices and mindset.

Though I cannot guarantee results, I feel confident that you will benefit greatly. If you are motivated, wonderful changes should hopefully result. This is why many packages do have a 30 day and in some cases, a 90 day, refund satisfaction guarantee. My smoking cessation programme includes six month support.
