Howdy from Billy Cart Behaviour

ABOUT US

At Billy Cart Behaviour, our name carries deep meaning — a tribute to two remarkable young lives who continue to inspire everything we do. The spirit behind Billy Cart comes from love, loss, and the joy of human connection. It honours Billy, a beautiful boy whose time here was brief but profoundly meaningful, and Ashton, a vibrant young person whose laughter lights up every room. Both have shaped the way we see the world: with compassion, determination, and a fierce belief in every person’s right to live fully, be seen, and be supported.

Billy Cart Behaviour was created from this place of purpose. We exist to walk alongside individuals and their support networks — not just to manage behaviours, but to understand them, meet needs more effectively, and support growth that feels safe, affirming, and real.

Our approach centres around Positive Behaviour Support (PBS) — but more than that, it centres around people. We don’t just write plans — we build partnerships, remove barriers, and help create environments where individuals can thrive in ways that are meaningful to them. Because at the heart of Billy Cart Behaviour is one simple truth: every person matters, and we’re here to make sure they feel it.
