He is committed to impartiality and to providing balanced, evidence-based, accessible reports tailored to each case’s needs. His assessments adopt a forensic approach, involving meticulous evaluation and triangulation of objective and subjective evidence. He is well-versed in the intricacies of medico-legal assessments and known for delivering clear, robust, high-quality reports and oral evidence to assist the court effectively, with complete adherence to Part 35 requirements. He is very happy to informally discuss potential cases and can assess and report with tight turnaround times if needed.
