Sometimes it can be difficult to find the right expert witness with the knowledge, credibility and experience to support your needs.

Dr Fiona Mason has an impressive range of expertise in providing considered opinion, and delivering independent reviews and medico-legal reports for civil and criminal cases and Mental Health Tribunals. She has vast mental health knowledge and experience in her specialist ­fields, which she can also bring to bear in her role as an expert witness.

Dr Mason has carried out a wide range of medico-legal work since she began training in forensic psychiatry. She assesses both men and women, although she has particular expertise in relation to the assessment of women, given that for the majority of her career she has specialised in the treatment of women with complex psychopathology. 

She undertakes both civil and criminal work, and has gained unique insights in post-traumatic responses and the links between trauma and offending, both in childhood or adulthood. In short, she can bring you the highest level of credibility and high level support when called on for any medico-legal work or as an expert witness.


I have known Dr Mason professionally for many years, both in her capacity as a lecturer and as an expert witness. She is rightly renowned for her expertise; I have also been greatly impressed by her clarity of thought and her ability to communicate complicated concepts in a way which makes them meaningful to the listener, whether her audience is made up of professionals or lay people.
