Clinical Negligence and Personal Injury Civil Litigation Expert Witness Psychologist

Independent Expert Witness Psychologist

Expert Psychological Evidence for Personal Injury and Clinical Negligence

I provide high‑quality, court‑compliant psychological expert witness reports for personal injury and clinical negligence litigation. My practice is built on more than 30 years of clinical experience in adult mental health, with particular expertise in severe and complex mental health presentations, trauma, and psychosis. I am HCPC‑registered and hold the Bond Solon Cardiff University Expert Witness Certificate (CUBS) in Civil Law and Procedure, ensuring that all my reports meet the standards expected by the courts.

My work focuses on high‑value, complex cases, and I am instructed by both claimant and defendant solicitors. I am also recognised by APIL as an expert witness.

Specialist Expertise in Injury, Trauma, and Clinical Negligence

My assessments draw on extensive NHS experience working with adults presenting with trauma‑related conditions, psychological adjustment to injury or illness, and the consequences of negligent medical care. This includes:

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

  • Consequences of clinical negligence, including 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

My reports provide clear opinion on diagnosis, causation, prognosis, and treatment needs, with careful differentiation between pre‑existing vulnerabilities, injury‑related symptoms, and factors influencing recovery.

Court‑Ready Reports and Robust Clinical Opinion

I produce comprehensive, concise, and defensible expert witness reports that comply with Civil Procedure Rules and the expectations of the court. My opinions are grounded in clinical evidence, transparent reasoning, and a clear understanding of the legal tests relevant to personal injury and clinical negligence claims.

Solicitors instruct me for:

  • Liability, causation, and quantum

  • Condition and prognosis

  • Treatment recommendations and rehabilitation planning

  • Complex or high‑value cases requiring specialist psychological expertise

Accessible, Responsive, and Efficient Service

My practice is supported by a staffed office Monday to Friday, ensuring that solicitors can reach me easily and that instructions, appointments, and communications are handled promptly. I offer fast turnaround times and clear scheduling, making the process straightforward for both legal teams and clients.

Assessments are available face‑to‑face or via a secure video platform, providing flexibility while maintaining confidentiality and professional standards.
