About Us


Mediation4 is run by Marc and Kathy Reid. Mediation4 is based in Berkshire in the Thames Valley and supplies mediation services and conflict management training to the whole of the UK.

Marc is an experienced professional workplace mediator and conflict management trainer.  He is author of the book “DIY Mediation. The Conflict Resolution Toolkit for HR”  and co-author of "8 Stages of Workplace Conflict".

Prior to setting up Mediation4 Marc worked for nearly 25 years in senior HR, commercial and general management roles for a FTSE 10 multinational company.  He set up and ran the company’s internal mediation service, having been trained and accredited by CEDR.  Whilst managing the service Marc recognised the power of workplace mediation, prompting his decision to leave the corporate world and set up Mediation4 in 2011.

As a passionate advocate of workplace mediation Marc regularly promotes its use to HR professionals.  Feedback has highlighted the need to improve HR and line manager skills in identifying and managing conflict. So using his experience as a manager and mediator he developed DIY Mediation to provide HR and managers with a structured, practical approach that enables them to resolve low-level conflict. Together with Kathy, Marc has trained hundreds of people to use the skills, process and tools of DIY Mediation.

Marc is a keen supporter of local community involvement, and is Lead Mediator and Vice Chair of Resolve, the Thames Valley based community mediation charity which helps resolve a wide range of neighbour disputes. Marc is a Civil Mediation Council Registered Mediator and has also worked as an Associate Consultant for Blake Morgan, a Consultant for Forbury People, a Consumer Conciliator for CEDR and a Prince's Trust mentor working with young people.

Kathy is a qualified mediator and experienced trainer. She is co-author of the book "8 Stages of Workplace Conflict".

Kathy works as a Trainer for Citizens Advice Reading and worked as a trainer for Resolve Mediation for many years, developing and delivering training to hundreds of adults, students and schoolchildren in conflict resolution skills and mediation. Working with Marc, Kathy has designed and delivered training in conflict resilience and mediation skills for both classroom and online delivery.  Kathy has a strong community focus and has worked as a Citizen's Advice Bureau Adviser, community mediator and mentor to young people.
