Sook Fern began practicing in 2014 in a restructured tertiary hospital. She has experience with a variety of child and adolescent presentations including anxiety, depression, eating disorders such as Anorexia Nervosa, self-harm, and suicidality. She uses an eclectic mix of CBT and DBT-informed therapy to help clients achieve change. As the young person is part of the family system, she also believes in helping caregivers learn how to support their young person to ensure that changes are maintained.

Sook Fern is trained to conduct a variety of psychometric diagnostic assessments, including those for dyslexia, ADHD, Autism Spectrum Disorder, and Intellectual Disability.

Sook Fern is trained to provide Family-Based Therapy (FBT) for Anorexia Nervosa, and was awarded the 2019 Team Health Manpower Development Plan Award (HMDP) for an attachment opportunity at Maudsley Hospital, where FBT first originated from, to gain new ideas and keep up to date on the newest methods of conducting FBT. Additionally, she is also qualified to conduct the Aussie Optimism Program, which uses CBT principles to help maintain a young person’s mental health.

In her free time, she enjoys relaxing at home, listening to music, and helping her son discover the wonders of the world around him.
