My style and my specialisms

I came to the practice of Conflict Resolution and Mediation through two distinct routes. One was through doing management consulting in the public and private sectors, and coming to understand just how much stress, inefficiency and sadness arises from communication and conflict difficulties in the workplace. The other route was through being a patient, a parent of children with disabilities and a family carer, and witnessing how difficult it can be to make plans for the future when the present involves difficult discussions and many people.

So I specialise in making sure that people feel comfortable with the process they undertake with me, and that it leads them towards feeling comfortable and confident about their future. I aim to be thoroughly supportive, reassuring and encouraging at all times.

My professional work and personal experience in health and social care mean that I am particularly experienced in supporting people who are living with any form of illness, disability, mental health condition or life-limiting condition. I have particular personal experience of working with people who are deaf or hearing impaired, on the autism spectrum, experiencing mental illness and living with dementia or stroke.

Why I love being a mediator

I came to mediation through a confluence of circumstances which made me think, ‘There must be a better way for people to deal with their difficulties than to threaten legal action, or refuse to engage in communication at all!’ I realised that a great deal of my management consultancy work was really… conflict resolution. It gave me such pleasure and relief when long-held rifts within and between teams melted away after some good, authentic communication. This piqued my interest to find out more about the art of conflict resolution, and I did my first certificated training, and started practising as a community mediator. Later I qualified as a civil and employment mediator, and have been mediating ever since.

It’s astonishing to witness people’s lives turn from a turmoil of distressing, intractable ‘stuckness’, to a new phase in which, for example, neighbours can conceive of greeting each other again; or work colleagues re-establish trust between each other after maybe years of mistrust, stress and non-communication. Mediation takes empathy, patience and persistence, and it is a skill I will develop and hone endlessly over years to come, but its core aspect is a belief that people really can find peace again, given the right support and a safe space to explore options for settling differences. Facilitating such processes is a real honour. Nothing beats the sight of former disputants smiling, shaking hands, or even (more often than you would think) hugging, at the end of a mediation.
