Expertise and Experience

Sue Castledine is a Chartered and Registered Forensic Psychologist and Associate Fellow of the British Psychological Society (BPS). Sue works for NHS England, as well as privately with Purple House. As an associate of Purple House, Sue works with adults who have a range of psychological issues including anxiety, depression and complex personality structures resulting in inter-personal difficulties. Sue also has specialist skills in working with individuals with anger management difficulties, both in individual therapy and in group settings. Primarily, she works within a CBT framework.

As part of her professional training and career path, Sue has worked with both forensic and clinical needs. Sue started her career as a Forensic practitioner in the prison service undertaking assessments and intervention work with high risk adult male offenders including life sentenced prisoners before working for the National Probation Service. This included working with individuals convicted of a broad range of offences including violence and sexual offences. In the past five years, Sue has worked as the Clinical Lead for a personality disorder service jointly commissioned by NHS England and NOMS (National Offender Management Service). This role has included working directly with offenders with complex needs including trauma, anxiety, depression and other presentations as well as those with a formal diagnosis of Personality Disorder. In addition to this, a significant part of the role has been undertaking workforce development activities including staff training and supervision. In her private work with Purple House, Sue focusses on work with non-offending clients, applying her experience of working with complex clinical presentations to mental health difficulties in the general population.

Sue has extensive experience in providing training, including training in suicide and Intentional Self Injury, personality disorder, complex needs, anxiety, depression and anger management.
