Sigma Therapies is a clinician-led practice in Bibra Lake looking for a psychologist (registered or provisional) to work across psychological therapy and Positive Behaviour Support with NDIS and private/self-funded clients across Perth.

You do not need to be a PBS practitioner yet.
If you are already considered suitable as an NDIS Behaviour Support Practitioner (Core or above), you can step straight into the full role.
If you are a psychologist who wants to develop into PBS, we will support you with supervision and a clear development pathway, and your PBS responsibilities will build as your suitability does.

Supervision from a Board-approved supervisor is provided in-house, and your salary, caseload and PBS involvement will be set to your registration stage and experience.
