Unsolicited feedback includes:

“ 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 …”

“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.
