About me

I am a Chartered Clinical Psychologist working in the NHS and private practice (in Streatham, South London) and registered with the HCPC.

I am a warm and experienced clinician who provides confidential, tailored and evidence-based therapies aimed at helping you to feel better and get back on track. I specialise in working with individuals and couples  with a wide range of difficulties (including depression, anxiety, panic, stress, trauma bereavement, low self-esteem, phobias, physical health issues, sexual difficulties and relationship problems) who would like advice and support to help improve their wellbeing and quality of life.

I can help you to understand how your difficulties may be being maintained and support you to make lasting change in the areas important to you. I draw on a variety of different therapeutic models and techniques depending on the difficulties you would like help with. These include:

  • Cognitive Behavioural Therapy (including Trauma Focused CBT),
  • Acceptance and Commitment Therapy,
  • Compassion Focussed Therapy,
  • Narrative Exposure Therapy,
  • Mindfulness, and
  • Psychosexual Therapy.

Getting started:
Please feel free to contact me either by phone or email. I will get back to you promptly to arrange an initial telephone consultation (free) in order to get a broad sense of what you would like help with. ​If I am not able to offer you help at this time, I will endeavour to signpost you on to alternative services.

Next steps:

1. Assessment
We will arrange a time to meet face to face and discuss in more detail what you are struggling with and what you would like to work on. The assessment process usually takes 1 to 2 sessions depending on the nature of your difficulties. Following this we will agree some initial goals for therapy, that we can review regularly to check we are on the right track.

2. Therapy sessions
We will plan a course of sessions together to work through your difficulties and help get you get back on track. The number and frequency of sessions is flexible, but can typically range from 8 to 12 sessions. Together we will plan things you can do between sessions to help maximise your progress. After therapy, when you feel you are back on track, it can be helpful to plan a booster session(s) to help you stay on track.
