Marilyn Webster

Director & Mediator

Marilyn trained initially as a family mediator in 1991 and has been practising continuously since. Over the last nearly 20 years she has been involved with the development of mediation practice and standards through various working groups and Directorships of national mediation organisations. Marilyn’s experience in SEN disputes dates back to the 2000 Code of Practice – and even before - as she was involved in a Regional Working Party that helped to draft the mediation sections of that Code before it was issued. She has been a keen advocate of the need for standard setting in mediation from the very beginning and has made various approaches over the years to standard setting bodies in the field of mediation. She was delighted when the issue of standards was finally taken up by the DfE and mediation bodies. Marilyn is an experienced trainer who has developed and delivered Approved Foundation and Continuing Professional Development courses, including in house SEND Mediation training to one of the first Regional SEND Mediation Services in 2001.

Louise finds SEND to be by far the most rewarding of all the types of mediation she has undertaken, because of the platform it provides for discourse between the local authorities and the parents, children and young people involved.
