How do you help clients?

I am the person businesses call in a crisis. Whether it is a fatal accident, major pollution incident or a dawn raid, I know how to deal with the enforcement authorities and press so that my clients can get back to business. Early intervention with the right expertise can stop an investigation in it tracks or significantly minimise its impact, which can be crucial for businesses and their management teams.
