Unsolicited feedback includes:

“Can I also reiterate my sincere thanks to you for your tireless professionalism and good humour through a very lengthy and difficult mediation. I think a deal was finally struck largely because you were able to find solutions to the numerous complex issues which arose.”

" I have availed myself of the services of about 8 mediators, and I think that you dealt with this one more adroitly than any of the others …”

"You will doubtless have heard that, perhaps against all odds, the parties managed to settle this dispute last night. I wanted to thank you for fantastic efforts to assist both parties, which proved invaluable. I think this is one of the more remarkable succesful mediations I have encountered, and I shall certainly keep it - and you - in mind next time someone opposes a mediation order saying "There is no point".

"I am writing to let you know that the litigation has now been settled on satisfactory terms. Your impeccable and incisive handling of the mediation proved to be a major factor in encouraging the two parties to reach a settlement, and we would like to thank you very much for your help."

“We would not have reached a settlement without your calm approach, determination and nuanced understanding of both sides’ positions. I appreciated your tireless efforts during the mediation to reach a fair solution that reflected our interests and values.”

It goes without saying (but I'll say it anyway) that it would certainly not have happened without your input, encouragement and persistence.”

“I just wanted to drop you a line to thank you for your role in bringing this mediation to a successful conclusion.  Your calming influence and determination to see this through was much appreciated throughout – as was your desire to see ‘fair play’ done and ensure that the investors’ position was not forgotten.”

“You are a very good mediator and even if we had no success this time, it was a thoroughly worthwhile process.  You had the complete confidence of my clients”

His approach to mediation is not to seek to impose his own evaluation of the legal merits of any dispute, but to focus on ensuring that parties have properly assessed the risks of their respective positions, creating consensus and exploring alternative solutions.
