Dr Shaun Parsons is a forensic psychologist and has been carrying out expert assessments for the courts for more than 14 years.

His recent professional practice has concentrated on applying a risk assessment model to parenting assessment. He particularly focuses on the association between personality structure as a method of explaining past difficulties and parenting and the use of this information to provide a risk assessment that is robust and based on sound scientific theoretical underpinnings. He is able to assess the risks of violence, substance use, personality difficulties and interpersonal relationships and their impact on parenting.

He has received specialist training on working and assessing sexual offenders and their families including partners' ability to protect. Dr Parsons also has a special interest in the assessment of capacity, especially of people with physical and/or sensory impairments.


Dr Parsons is trained in EMDR and solution focused therapies and is experienced at undertaking group and individual therapy.

Alex is actively involved in research into domestic violence programmes in collaboration with Nottingham Trent University, continuing on from peer-reviewed research into domestic violence perpetrators involved in family court proceedings. His previous research includes a thesis establishing effective elements of CBT programmes with adult and adolescent offenders; individual differences of domestic violence perpetrators and the efficacy of assessment tools used for young offenders in formal forensic settings.

Alex also has a background of lecturing at universities and delivering training and workshops for other professionals, including sexual risk management to the police service, court room psychology to social workers and neurological difficulties and behaviour management to professionals working with adolescents in forensic settings.
