About me

Hi, I’m Sarah. I love working with people to discover their deeper truths, connect with what really matters to them, and create the life they want. I have extensive experience working with anxiety, depression, trauma and the emotional impact of physical health conditions, as well as helping survivors of narcissistic relationships. I particularly enjoy working with people who are polyamorous or practise consensual non-monogamy, and with people involved in kink and BDSM. I offer a warm, sex-positive space where we can explore your experiences with openness, curiosity and respect.

I have over 20 years’ experience as a qualified Clinical Psychologist, working in the NHS, the charity sector and private practice. I draw on psychological and trauma therapies, including EMDR, CBT, ACT and CFT. I have a strong interest in energy psychology, where Eastern energy approaches have been combined with Western psychological therapy.

My approach is collaborative and tailored to you. Together, we can explore the experiences and underlying patterns that keep you stuck and work towards lasting change. Spirituality is welcome in our work. I offer individual therapy online, and you’re welcome to get in touch for a free initial 15-minute conversation.

Training, qualifications & experience

Therapies

I am trained in a range of therapies including:

  • Trauma therapies: EMDR, trauma-focussed CBT and energy psychology.
  • Third wave CBT: Acceptance and Commitment Therapy and Compassion Focused Therapy.
  • Energy psychology, including EFT, Blue Diamond Healing, Ask & Receive and Logosynthesis.

Why See a Clinical Psychologist?

Clinical psychologists have a three-year undergraduate degree in psychology plus a three-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 15-minute telephone consultation so that we can both work out whether my therapy would be a good fit for you.

Sessions cost £120 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.

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.
