35 Years experience:
Gerry O’Sullivan’s experience and accreditation in many areas of dispute resolution such as Organisational & Workplace Mediation, Civil & Commercial Mediation and Community Mediation has given her a very sound and firm understanding of the nature of conflict, its causes and what is necessary to help parties to reach resolution. Her experience has not been solely confined to dual party dispute as she has an extensive portfolio of expertise in facilitating large and small group disputes and inter-party disputes. As well as extensive work in Ireland, she has worked in Northern Ireland, in Serbia and in Palestine/Israel. She has been trained in Mediation in Post-Conflict Countries by CSSB Berlin and in The Evaluation of Peace Interventions by INCORE, University of Ulster, Northern Ireland.

Gerry has authored a book: 'The Mediator's Toolkit: Formulating and Asking Questions for Successful Outcomes.' Publishers: New Society Publishing, Canada, She has also developed training programmes, with filmed demonstration role plays, based on this book. 

Gerry has delivered training in Conflict Resolution, Mediation Skills and Interest Based Bargaining (Management & Union Negotiation). Gerry is currently delivering training in Mediation to an M.A. programme in Peace and Development Studies, University of Limerick. The training programme that she has developed for Certified Mediation is approved by The Mediators’ Institute of Ireland.

Gerry is trained in the conduction of Investigations into Bullying & Harassment. She was on an approved panel of consultants with the Equality Authority delivering training and consultancy through Equality at the Level of Enterprise.

Gerry O'Sullivan has been working as a consultant facilitator and trainer since 1986. She also works in the areas of project research and evaluation. Her contracts have come from the public service sector, the community sector and the commercial sector. Her previous background was in the Health Sector. The broad range of people with whom Gerry O’Sullivan has worked over the last twenty years has led to her capacity to understand the diverse needs and interests of individuals and groups from many different backgrounds.

Reference from J. Murphy: "The situations that I have seen Gerry OSullivan mediate have been complex and difficult. I consider her to be one of the most highly skilled consultants working in the organizational development field in Ireland. Her overall approach is characterized by clarity, focus, incisive intelligence, efficient use of time, and warmth and respect towards the parties that she engages with. She has a remarkable capacity to clarify and hold boundaries and to ensure that all parties involved in dispute resolution respect the agreed boundaries within which the mediation process proceeds. She is a very clear communicator, as well as being organized, reliable and thoroughly professional in her approach. I believe that parties engaged in dispute will find themselves in a very experienced, safe, firm, intelligent and competent pair of hands if they contract Gerry O Sullivan to work with them towards resolution. She has the ability to: o Elicit clear briefings in advance of mediation sessions and to prepare accordingly. o Establish rapport and trust with parties at a very early stage o Very clearly set the scene for the mediation and to ensure that all parties are clear on the parameters of the process and feel safe. o Listen intently and to convey to parties that they have been heard - through fine tuned feedback o Keep parties on focus and to intervene in a firm but respectful way when people tend to digress from the issues at hand o Pose incisive questions that move to the heart of the issues involved o Change tack if the particular line of questioning is not yielding fruitful information o Stand own ground and to hold the mediator position – I have seen Gerry do this very effectively in situations where one of the parties sought to undermine her and the process. o See through and resist attempts to manipulate the mediation process o Keep the process to agreed time schedules and to ensure that adequate time is given at the end of the session for closure.
