Any successful clinical negligence case is the product of team work and for me this is one of the most satisfying parts of the job. The clients are a vital part of the team and not just passive recipients of “expert” services. They are of course experts in their own lives and experiences.

“It is not my style to out-expert the expert. I find I get the best results by being an informed enquirer.”

Clients need a clear and accessible explanation of the strengths and weaknesses of the case. This is the foundation for building a relationship of trust, empowering the client to make the best choices as the case progresses. Many of the cases I deal with are extremely complex and it can be challenging to explain a case in a way which is accessible but not oversimplified or patronizing.

A case is not a battle of wits between barrister and medical witness. It is not my style to out-expert the expert. I find I get the best results by being an informed enquirer.

Patients need to understand what went wrong in their treatment but perhaps more importantly they need appropriate compensation. Medical treatment and care is very expensive and increasingly hard to access unless compensated. I have seen how compensation can turn an individual’s life around and it is a privilege to feel I have made a difference.
