Defensible Psychological Evidence

Independent, court‑ready psychological evidence for complex, high‑value civil cases.

My reports deliver clear, defensible opinion on liability, causation and quantum, grounded in rigorous clinical assessment and CPR‑compliant medico‑legal practice.

I assist both claimant and defendant solicitors with precise, evidence‑based conclusions that support robust decision‑making.

With over 30 years’ specialist experience in adult mental health, I bring advanced expertise in severe and complex presentations. My reports set out authoritative opinion on diagnosis, treatment needs, and prognosis, with careful, structured differentiation between pre‑existing vulnerabilities, injury‑related symptoms, and factors influencing recovery.

Assessment Scope

I have extensive NHS experience in trauma‑related conditions, psychological adjustment to injury and illness, and the consequences of negligent medical care. My expertise includes:

  • Psychological impact of personal injury — trauma, adjustment disorders, chronic pain‑related distress, and functional impairment

  • Consequences of clinical negligence — delayed diagnosis, surgical error, obstetric injury, and adverse treatment experiences

  • Psychological adjustment to medical conditions and long‑term health consequences

  • Trauma‑related presentations in veterans and individuals exposed to high‑intensity events

  • Complex mental health presentations, including psychosis and severe mood disorders
