Jonathan Zimmern | Fieldfisher
Skip to main content

I have 20 years' 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,  cancer care and orthopedic injury. I also represent clients at inquests.

I regularly act for severely brain-damaged babies, securing multi-million pound awards for their care, as well as for clients fighting difficult and complicated medical and surgical cases.

I am known for my forensic analysis of medical and legal issues in complicated cases and for being able to cut to the heart of a claim. I always fight for the very best outcome for my clients.

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

I am a qualified barrister and speak at conferences to medical professionals and other lawyers. I also act for the Trustees of the vCJD Compensation Scheme, managing a compensation fund of £67.5m.

Last year, I recovered damages for my clients in excess of £39.6m. A recent career highlight has also been succeeding in the Court of Appeal in a ground-breaking and complicated case involving duty of care in a genetics case (ABC v St Georges'). Read about the case.
