For 23 years I have been  working with people of all ages to help them improve their psychological health. I originally trained as a Child and Adolescent Clinical Psychologist, and still love helping children, young people and their parents.

Over the years, I’ve been fortunate to work in a wide range of excellent services. I’ve worked in Public Mental Health, Secondary Schools, Hospitals, Community Health, and Learning Difficulties Services in both Australia and the UK.

I began supervising Psychologists, Registrar Psychiatrists and other Allied Health Practitioners in 2004. I very much enjoy training and supervising, and am pleased to still be doing this in Private Practice.
I work flexibly with a strong connection to my clients, to help them improve their mental health, well-being, relationships and lives. I enjoy enabling people to be happier and calmer; to meet their goals in life and achieve more; to learn and develop better; and to have better relationships. I work with:

  • Children (4yrs +)
  • Adolescents
  • Young Adults
  • Parents with depression, anxiety adjustment and stress, parenting/carer issues, family issues, separation and divorce
  • OCD in children, adolescents
  • Anxiety in children, adolescents
  • Phobias
  • Health-related issues, including Chronic Illness and Somatic issues (medically unexplained symptoms)
  • Parenting and family management
  • Bereavement, loss and separation

I love providing formal assessments of neurodevelopmental and learning disorders, such as ADHD, Autism, and Specific Learning Disorders. Assisting clients with these conditions and their parents is a passion of mine.
I focus on helping people using scientifically proven therapies including Cognitive-Behavioural Therapy, Interpersonal Therapy, Motivational Interviewing, Mindfulness, Narrative and Solution-Focused Therapies.

I am endorsed by the Australian Health Practitioner Regulation Agency (APHRA) as a Clinical Psychologist and an Endorsed Supervisor of other Psychologists. I am also a member of the Australian Clinical Psychologists Association.
