Career

I am a Partner in the Medical Negligence team.

I have more than 30 years' experience in medical law, and I specialise in the interests and rights of birth-injured children (obstetric and neonatal) - particularly those affected with catastrophic injuries where compensation awards are very high to ensure provision for their future needs.

I agreed a £33m settlement for a 15-year-old boy with cerebral palsy and complex cognitive and behavioural needs, one of the highest awards of its kind and the largest ever for a teenager. I also negotiated settlement for a 7-year old boy with severe behavioural problems, autism and ADHD to the value of £30m.

My cases regularly receive media interest. I have been quoted in the national and local press and interviewed on national TV and radio. I appeared on BBC2's Victoria Derbyshire Show with a client who spoke about her cerebral palsy via eye-gaze technology.

I lecture on best practice in obstetric cases and present to the Trust for Children with Brain Injury (Surrey), Chailey Heritage School (East Sussex) and SCOPE (London).

I am a Law Society accredited Clinical Negligence Specialist, a member of the AvMA Specialist Clinical Negligence Panel and an APIL Fellow.

In 2022, I completed the Land’s End to John O’Groats challenge, and in 2025, I undertook a 9-day cycle ride across Ireland from Mizen to Malin, raising funds for Fieldfisher’s One Firm Action initiative in support of the charity Access Sport.
