"Our mission can be encapsulated in one word: inclusion,"Dr Lin said.
"This oral health care service includes everyone, as disability could affect any one of us at any point in our lives, through accident, illness, injury or ageing."
"If it wasn't for Trudy we wouldn't be a happy family right now,"Ms O'Callaghan said.
"When he saw Trudy his face even lit up, he actually initiated, he walked up and gave her a hug, he doesn't do that with just anyone,"she said.
"If we can expand the knowledge and understanding of how best to support someone with a disability ... we can start to make those really big differences and our investments are better because people know how to use those investments."
