My Professional Background
I specialise in complex, high value medical negligence, fatal accident and preventable suicide cases. I am responsible for a wide range of cases, including surgical error, misdiagnosis and sub-standard nursing and midwifery care. I am particularly interested in claims involving injuries to mother or baby during pregnancy and labour. I also represent families at inquests.
I became a Partner at Attwaters Jameson Hill in 2009 and Head of Medical Negligence Dept in 2014. I am the Firm’s LEXCEL Senior Responsible Officer (SRO) and a Professional Trustee on a number of multi million pound Personal Injury Trusts.
