Our Story

The Arriba Group identified a crucial gap in high-quality allied health services for individuals with disabilities, particularly those with NDIS plans. Marcella Romero, the founder of the Arriba Group and a former occupational therapist, applied her first-hand understanding of the unique needs of people with disabilities to establish LiveBig.

Recognising the importance of delivering a high-quality service, the Arriba Group combined two of its strengths – our expert disability knowledge and our people – to launch LiveBig in 2019.

LiveBig now supports people in four states via face-to-face support and nationally via telehealth. While the organisation has grown, our people-centric participant-first approach has remained constant.

Painting of the Arriba Journey

The middle symbol is the main symbol of the painting, which represents The Arriba Group. 

The surrounding red symbols represent the other enterprises under The Arriba Group, Rehab Management, AimBig Employment and LiveBig.

The white symbols around these represents the men and woman of the Arriba Group, alongside with the footprints. These represents everyone’s journey that are apart of or have been a part of The Arriba Group. Marcella’s, the workers and the customer/client’s journey.

The blue arms represent the connection of the enterprises to The Arriba Group and shows combined, they’re all one.

The brown and orange dots together represents that no matter of the difference of a person, we are all the same.

Throughout the painting it shows colours that make The Arriba Group, red and grey being two of the main colours.
