Our Team

Ascending Psychology has a team of specialised Clinical and General Psychologists to meet the needs of our clients and the community.

Sarah Campbell, Principal Clinical Psychologist

Sarah is a Clinical Psychologist specialising in the treatment of complex and chronic conditions. She started her career working in the forensic field, treating high risk clients who suffered from severe mental health difficulties, addiction, disability and who had committed serious offences. In this capacity, she served as an expert witness to the courts, preparing reports to assist in determining whether someone was fit to stand trial or a risk of re-offending. Thereafter, she has worked in offshore processing and in remote indigenous contexts. Sarah therefore relies on various different therapy techniques and theories to meet the needs of her clients. This includes Dialectical Behaviour Therapy, Mindfulness, Trauma Informed Practises, Narrative Approaches, and Cognitive Behavioural Therapy. Most importantly, she passionately supports clients to identify the underlying difficulties that are contributing to their suffering and encourages them to move through this with a balance of acceptance and change.
