What drives you in your career?

I do get a kick out of resolving disputes, representing interesting clients and trying to bring parties together to broker a deal.  At the same time, I also enjoy the thrill of the Court room and fighting hard for a result.

Why did you choose dispute resolution as an area of law to specialise in?

I remember being taken to Court to attend a hearing as part of a work experience placement in the 1980s and I was immediately hooked on litigation.  I was pleased to be offered a position in my then firm’s litigation department upon qualification as a solicitor and have not looked back since.

Are you one of those lawyers that just advise clients to settle?

I hope not.  I do believe in standing up for your rights and not selling yourself short.  However, I settle more of my cases than the national average but importantly on terms which I, and more importantly my clients, believe are fair.

What have been the most interesting cases you have been involved with?

I have to say that although I have been involved in substantive commercial litigation over the years, the cases which really stand out are those in which I have represented individuals or groups with personal issues which have hit the news headlines.  The use of the media to expose wrong doing has always interested me.

What was your most embarrassing professional moment?

This has to be the time I was conducting a trial in South Yorkshire when the seam in my trousers decided to give up.  I had to run out during the lunchtime adjournment and buy a new suit.

What else do you do at Raworths?

I take a particular interest in the firm’s marketing and social events.  I have also set up our Corporate Responsibility Programme called Raworths Responds in which we put in a team of helpers into the local community to make a difference.

What interests do you have outside work?

I have always had an interest in politics and I stood in the General Election in 2005.  Nearly 9,000 people voted for me but it was not sufficient to get elected.  I will therefore stick to being a solicitor.

A client says:  “He is tenacious, thorough and exceptionally experienced in his field. We have always felt very confident following his recommendations and believe he has gone the extra mile with his proactive approach.”
