What Others Say

Mediation Services

"After 25 years of good old fashioned litigation I would describe myself as a mediation sceptic, that is, until I experienced Toby Walker and the team at ADR Group who showed me and my clients how it's really done and why it can be relied upon to produce results"

Mediation Services 

"ADR Group is a well-run and efficient service provider.  They listen to your mediation requirements with care and make sure they pair you with a mediator suited to your needs.  Everything is done in a very timely manner.  My first point of call, always" 

Mediation Services 

"ADR Group make organising mediations easy"

Mediation Training 

"I had already trained with a lesser known mediation company, though I wish I hadn't. Once I started to train with ADR Group, I realised how much i'd missed out on and how much I had to gain by training correctly. The trainers at ADR Group were the most helpful, friendly, informative and supportive trainers I could have ever wished for. The training was fun, informative and interesting and I am forever grateful to ADR Group for helping me along the way."

Joanna Nutley

Mediator Training

"I was extremely impressed by both the content and the delivery of the course particularly given the need to deliver it remotely. I have heard colleagues talk about mediation training that they have undertaken recently with other providers and this course would certainly appear to be more comprehensive than those."


Mediation Services

"I must say I was very impressed with the service received from the ADR Group and I will certainly be using you again in the future. Right from the start I was highly impressed with Sam; his responsiveness and communication was excellent."  Legal Counsel

Practice Overview

Stephen has personally mediated over 800 mediations with a 87% settlement rate (over the last year).  He is ranked in the top 40 mediators in the UK in both Chambers and the Legal 500 Directory 2021 which describe him as having:


"a relaxed firm style with a sense of humour”

“a strong personality without being overbearing”

“gravitas which clients like”

“the ability to be succinct"

"He cuts through the nonsense and is practical, assertive and imaginative." 
"He thinks on his feet and addresses the issues at hand during the mediation, coaching parties into sensible positions and balancing commerciality with the legal aspects of a case."

His approach is to identify the obstacles to settlement and help the parties get over them.  Many of his mediations come from referrals or repeat instructions.  Clients value his proactive "we can do this "style.  

Stephen has a 360º experience of mediation: as a mediator, a mediation advocate and as a client himself.  He understands what mediation is like for clients and their representatives.

You were brilliant” – Claimant in a construction dispute.

“We couldn’t have done it without you. A truly fabulous result” – Highly experienced Commercial Litigator.  

It was very well done and achieved a settlement that I thought initially would never happen and certainly not on such fabulous terms” – Experienced Midlands Litigator

For my part I will certainly be recommending you as a mediator and am not surprised that both sides were very happy with you” - Chancery QC

“Facilitative mediation my a***” – Solicitor, Mediator and Deputy District Judge

“You did an excellent job with tact and humour. You also managed to do that most difficult thing of sending everyone away apparently happy with their lot” – Experienced Chancery Barrister.

I have no doubt that we will be turning to you again in the near future. I intend to let the rest of the department know about your services and to endorse your expertise” – Commercial Barrister and Mediator.

“Brilliantly done. It was a fun day” - Managing Director of an international trading company

“You were a magician to settle two disputes in one day - Finance Director of well-known leasing company

“I found you to be very pro-active for a mediator and your input was vital in persuading my client to adopt what I would call a sensible commercial approach”.  Commercial Solicitor.

Very assiduous, incapable of being intimidated, imaginative, highly intelligent, determined and courteous” - Experienced Solicitor and Mediator

“I thought that you were most effective and pushed and probed at just the right times… I can see light at the end of the tunnel now after four years of darkness” – In house counsel for a national construction company.

“Calls a spade a spade and that was needed”- Experienced Commercial Solicitor

“I must say that last week’s mediation was by some distance the most constructive mediation I have taken part in,.  For me the real difference was your approach, combining as is did a light touch with a willingness to address the legal issues where necessary.  This left me with a sense that although the settlement was ultimately a commercial one it had been reached with an understanding and appreciation of the parties’ respective legal positions.  This contrasts with the crude mechanistic approach I have seen used in the past which almost seems to make a virtue of ignoring the parties’ legal rights.  You obviously have a real feel for the mediation process and I am therefore sure that you have no need of it but if asked to suggest a mediator I will have no hesitation in recommending you” - an Experienced Chancery Barrister

You lent an extra pair of ears to my clients’ hilarious but interminable – anecdotage – Senior Chancery Barrister
