Dr Siobhan Blackwell

Chartered Clinical Psychologist


Chartered clinical psychologist, cognitive analytical therapist (CAT) and dialectical behavioural therapist (DBT) specialising in adult mental health and older adolescents.

I completed my clinical training on the Oxford doctoral course of clinical psychology, which is closely affiliated with the Oxford cognitive therapy centre, a centre of excellence for cognitive behavioural therapy (CBT). My final year of this programme was based at The Tavistock clinic, which specialises in psychodynamic work. My post-doctoral training in cognitive analytical therapy (CAT) provides a framework which combines the best of these models. I have a wealth of experience spanning over 20 years and draw flexibly on these models to meet a wide range of presenting problems.

I’m committed to ongoing professional development and I’m registered with the British psychological Society (BPS), The Association of Cognitive Analytical Therapy (ACAT) and The Health and Care Professions Council (HCPC) and I adhere to the code of ethics set for these governing bodies.
