Carol is trained in Child and Adolescent psychotherapy and works with children and adolescents in a developmentally and age appropriate way, using various approaches including play, creative mediums and attachment informed therapy.  Carol also tailors therapeutic support for parents and carers, working systemically to support the development of children.  Carol provides consultation on emotional and behavioural difficulties and has extensive experience with the symptoms of trauma, attachment/relationship and developmental issues.

Carol has a special interest in Somatic Experiencing (SE) and provides this intervention to both adults and adolescents.  Somatic Experiencing is a comprehensive form of healing that recognises the integral relationship between body and mind in moving towards greater resiliency and well-being.  SE understands that both stress and trauma is a natural part of life that affects us all.  Trauma, chronic stress and overwhelming experiences can contribute to nervous system dysregulation.  Sometimes we can be left feeling shut down, disconnected, anxious, emotionally charged, coping with physical illness/pain or other lingering problems.  SE works to increase capacity to regulate the nervous system and release stuck patterns.  It supports a movement towards living in the present in a healthy balanced way.

Services include: Somatic Experiencing, Individual psychotherapy, parent/child relationship work, therapeutic parental support, consultation
