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

David Harris

Civil & Commercial, Workplace and Online Mediator


Practice Overview

David uses his highly pragmatic approach to resolve difficult and seemingly intractable disputes. He has a relaxed approach whilst listening to parties' needs and concerns and then steering them towards a resolution of their differences. 


David draws upon over 30 years of experience as a commercial litigation solicitor. His knowledge and understanding of the technical and procedural issues (and the costs) that can bog down parties in litigation help him to grasp very quickly the best route forward for the parties and where appropriate to press the parties to reality test their current position. 


David has a calm and relaxed style but he is not afraid of taking a "hands on" approach and being blunt with the parties where it is necessary. He also has experience of handling mediations where there are language barriers and the parties have brought translators along to assist them.
