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
