Our story
Peter Walker & Associates Clinical Psychologists was founded in 2002 by Peter Walker who had been working as a clinical psychologist since 2000.
The practice offered psychological treatments for those experiencing difficulties with anxiety, depression and couples in distress. It was unique in that it also offered specialised treatments for those experiencing psychotic disorders and bipolar disorder. At that time, the development of psychological treatments for these conditions was in its infancy and Peter was considered an innovator in this field.
Over the years, the Randwick practice has grown to include several clinicians, each with their own areas of interest. The predominant model used by our clinicians is Cognitive Behavioural Therapy (CBT) and related approaches within this framework. All of our clinical psychologists have undergone extensive training in the implementation of evidence based approaches either through Masters, Doctorate or combined PhD/Masters degrees in Clinical Psychology.
