I was once told that where a businessman always looks in a transaction in terms of what can go right, a lawyer looks at transactions in terms of what can go wrong. An eternal optimist, I make sure that I have firmly in mind the commercial and reputational objectives of each client when advising on regulations and potential legal risks.

“I have come to appreciate the value of a pastoral approach to client care”

Ever an inquisitive individual, I still get excited when faced with a novel point of law. Years of broadening my practice into different (albeit related) areas of law have provided many opportunities to think outside the box and draw on law developed in other fields.

Through my experience of dealing with vulnerable or financially exposed clients, where the legal process they face is difficult if not life changing, I have come to appreciate the value of a pastoral approach to client care.
