We have set up Fitzwilliam Psychotherapy to offer psychotherapy in comfortable, pleasant and open environments with Centres located in Dublin City Centre, South East Wicklow, Carlow/Kilkenny and the Galway/Roscommon/Mayo border. Psychotherapy is about helping the person to further develop a sense of meaning, purpose and direction in life; at the same time, and toward these ends, it involves looking at things that are usually difficult to consider or what we have put to one side and of which we are no longer even aware.
At each of the centres, we work exclusively with adults and usually on a one-to-one basis. While we at times receive referrals from professionals, we work mostly with people who make contact with us directly. We also offer psychotherapy online.

While many of our clients seek psychotherapy because they experience anxiety or depression at a level, people vary greatly in what brings them to seek a consultation. A major event in life may call for a re-evaluation of things in general. Feelings of guilt or shame can be very powerful and call for some exploration. Many people become stuck in their lives and unable to make the kinds of changes they wish to make. For many people, relationships may be difficult; there may be a fear of intimacy, feelings of intense anxiety with others and experiences that are difficult to come to terms with, in spite of the passage of time. At times, our suffering gets caught in our bodies and, if we do not actually become physically ill, we become very concerned about physical illness or the possibility of illness, which can become highly debilitating.

Though we have all trained as psychotherapists, we have each areas of particular experience and interest.
