About Inner Truth Psychology


About Me

My name is Dr Sarah Marzillier. I am a clinical psychologist who has spent many years working within the NHS. I am experienced working with adults, adolescents and older people. Over the 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, other chronic health conditions and people coping with the aftermath of events such as head injuries or stroke.


My Approach

I believe that everyone has a different route to happiness. My approach involves helping people to find what they need to do to be happy.

In practice, I try to listen carefully to what people are telling me. When I feel that I have heard and understood what is happening for the person in front of me, then I will suggest ways forward that I think will help.


I am trained in a range of different therapies, including:

  • Cognitive behavioural therapy (CBT)
  • Acceptance and Commitment Therapy (ACT)
  • Eye Movement Desensitisation and Reprocessing (EMDR)
  • Compassion Focussed Therapy (CFT)
  • Interpersonal Therapy (IPT)
  • Emotional Freedom Technique (EFT)

Neuropsychological Assessment

I am also very experienced in formal testing to identify strengths and weaknesses in cognitive processes such as memory and intellectual functioning. This can be particularly useful after a head injury or a stroke or when people are concerned about having a deteriorating condition such as a dementia.
