About BSSA

Who We Are

Behaviour Support SA (BSSA) is a small but dedicated team of Positive Behaviour Practitioners.

We aim to improve the quality of life and self-esteem of participants of all ages with disability or integration difficulty through building the capacity to live an ordinary life.

Our therapy services offer support in challenging behaviour, social interaction and empowering people and families to manage challenges as they arise.

We believe in a person first approached that is tailored to individual needs and requirements to encourage the outcomes you want.
