Samuel is one of Australia’s foremost experts in person-centred practice models, with a strong emphasis on services for people with a disability.  He has provided a wide array of professional supports to people with a disability, their family and carers, service providers, and government departments for more than 15 years.

Samuel holds a Bachelor of Applied Science (Disability), and is the Immediate Past President of ASID (Australasian Society for Intellectual Disability - Victoria Branch), and a current Australasian Board Member.  Samuel was awarded the Victorian Disability Support Worker of the Year Award (2006) and went on to play a pivotal role on the statewide awards selection panel, notably seeing the launch of a DSW Team of the Year Award in 2008.

In addition, Samuel contributes to a number of ministerial panels and was also an inaugural member of the Office of the Senior Practitioner Research Reference Panel.

For over five years, Samuel was the Chair of the annual DSW Conference. This widely acclaimed conference attracted over 800 delegates from across Australasia, and abroad. He is also currently involved in research projects with the Living with Disability Research Centre (LiDs) at La Trobe.

After being awarded a Churchill Fellowship, Samuel has taken up the challenge to improve the quality of support being provided to people with a disability.  A number of current national and state workforce initiatives overseen by NDIA and the Department of Health and Human Services are just some of the projects Samuel currently commits his time and experience to.

Samuel is currently working with a Victorian provider, on a long term project, to devolve a number of large institutional residential aged care settings, into a small home model of support based on the Green House and Eden Alternative models from the United States.
