Mr Jonathan Zimmern > Fieldfisher > London, England > Lawyer Profile


Work Department

Medical Negligence Solicitors




I am a partner within the Clinical Negligence Team at Fieldfisher. I have over 14 years of experience dealing with complex, high-value medical negligence cases. I am a qualified barrister and my work covers many areas including birth injury, brain injury, delayed diagnosis, spinal and orthopaedic injury, nursing negligence and surgical negligence.

I act for the Trustees of the vCJD Compensation Scheme, which manages £67.5 million for families affected by vCJD.  In 2017, I won a potentially ground-breaking case in the Court of Appeal which considered the legal duties of care that clinicians might owe to relatives of patients who they are treating for genetic conditions.

I am described in the legal directories as a qualified barrister who is “skilled in handling high-profile cases relating to spinal injury, plastic surgery and birth injuries” and as a lawyer who is “very thoughtful about evidence and tactics”, “passionate and courageous” with “…an incredibly inquisitive and analytical mind”, “meticulous preparation of cases, sound forensic judgment and impressive command of medical issues”. I have been noted as “super-bright and really switched on…”, “… an excellent tactical thinker, he has a very good eye for the appropriate commercial settlement and his judgement is outstanding.”

The team at Fieldfisher is led by ‘titan in the clinical negligence field’ Paul McNeil, and is recognised for its ability to act on the most complex cases in this area, with a particular focus on those including birth complications; genetic metabolic disorders; delayed diagnoses of cancer; spinal injuries, cerebral palsy and psychiatric injury. The team acts on cases of varying financial level, though claims are often for values in the multi-millions; ‘ferociously hard-working’ partner Samantha Critchley is currently acting for a premature baby on a case with an estimated value of £30m. The team is often able to provide its clients with early rehabilitation and has international reach. Kate Rohde‘s presence continues to inspire praise from the market. Catastrophic injury specialist Jane Weakley is a consistent standout in the team, as is former doctor Iona Meeres-Young. Legal director Caron Heyes is known for her work with charities including Child Bereavement UK, Inquest and Mencap, while senior associate Suzanne Farg, who joined from Kingsley Napley LLP in April 2021, is also one to watch. Mark Bowman and Jonathan Zimmern complete the roster of recommended practitioners.
