Clinical Psychologist

About me

I am a clinical psychologist with over 17 years' experience working in the NHS, private practice and palliative care.  Although painful, times of difficulty can be times of great potential. It is often during these times that we begin to understand what really matters to us, and this can lead us to develop more fulfilling lives.

I have many years experience working with people who have experienced trauma, have chronic health conditions, or who are anxious or depressed. As well as being trained in CBT, third wave CBT and EMDR, I have expertise in energy psychology and spirituality.  

I am polyamory and kink aware. I am sex positive and supportive of diverse relationship orientations, sexualities and lifestyles.

What to Do Next

If you think you might be interested in seeing me, then please email me through the website or call me on 07522 450369. I offer a free telephone consultation service to see if my approach will be a good fit for you.

I am now offering online therapy sessions so please let me know if you are interested in this option.

The first session is an assessment session, where we both work out together whether psychological therapy would be a good approach for you. If we think that it would be, we can then go ahead and book some more sessions. We can book on a session-by-session basis, there is no requirement to have a certain number of appointments. Everyone is different, of course, but a rough ballpark figure of about 10 sessions is quite common

Training, qualifications & experience

My Experience

For over 17 years I have worked in NHS mental health services and hospitals and private clinics. I have worked extensively with people with low mood, anxiety and people who have experienced traumatic or distressing events. I have also worked with people with a range of health conditions, including headaches, chronic pain, cancer, headaches, other chronic health conditions and people coping with the aftermath of events such as head injuries or stroke.

I work with alternative relationship orientations and sexual preferences including polyamory, BDSM and other types of kink.

Why See a Clinical Psychologist?

Clinical psychologists have a longer training than most counsellors and psychotherapists. We have a 3 year undergraduate degree in psychology plus a 3 year doctorate in clinical psychology. In practice this means that we have an in-depth grasp of psychological processes and how these can affect well-being. Clinical psychologists are trained in a variety of different therapies. This means that we can create a bespoke therapy for each individual, choosing from a range of different techniques to suit each person and the issue that they are facing.

Additional information

I offer a free telephone consultation so that we can both work out whether my therapy would be a good fit for you.

Sessions cost £100 for a 50 minute session. Clinical psychology sessions tend to be more expensive than counselling or psychotherapy. This is because clinical psychologists have a longer training (3 year undergraduate plus 3 year postgraduate to a doctoral level). We are also trained in a range of different psychological approaches. In practice this means that we can choose from a range of different techniques to suit you and the issue that you are bringing to therapy. In this way we hope to offer a bespoke therapeutic approach. We also aim to work quickly to reduce distress and enhance well-being, so that it may be possible to improve in fewer sessions.

I offer reduced fees for people who are currently unable to work, please contact me and let me know if you would like to know more about this.

I am registered with all of the main insurance companies, including Axa, Bupa, and Vitality.

When I work

Monday to Fridays between 9am and 3pm.

Further information

I am also now seeing people for online therapy. You would simply need a private space and access to the internet. This allows me to see people across the UK and is more convenient for many people. Online therapy is as effective as face-to-face therapy.

I see people on Mondays and Thursdays from 9-3.

Wheelchair user access

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a Counsellor's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the Counsellor to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.
