I have over 16 years of experience dealing with complex, high value medical negligence cases covering all areas of treatment, including birth injury, delayed diagnosis, surgical negligence, brain and spinal injury, wrongful birth, gynaecology and cancer care, nursing care and orthopedic injury. I also represent clients at inquests.

I am a qualified barrister and have spoken regularly on clinical negligence, both to medical professionals and to other lawyers. In addition to my clinical negligence practice I act for the Trustees of the vCJD Compensation Scheme, managing a compensation fund of £67.5million.

I have experience dealing with complicated cases of clinical negligence that overlap with pre-existing personal injury claims and am often instructed to take over cases mishandled by other solicitors.

One of my proudest moments was succeeding in the Court of Appeal in a ground-breaking appeal involving duty of care in a genetics case (ABC v St Georges'). I regularly act for severely brain damaged babies securing multi-million pound awards for their care, as well as for injured clients fighting difficult and complicated medical and surgical cases. I am known for my forensic analysis of the medical and legal issues of my cases and for my ability to cut to the heart of a case. I will fight to ensure the best outcome for my clients.
