Mark Guy

Medical Negligence Solicitor


“Working closely with experts and learning about medicine is a fascinating part of being a medical negligence solicitor. It is particularly satisfying to run a case from start to finish and, when a claim succeeds, you can see first-hand how it can help people get their lives back on track.”
