Peter started to work in youth and young adult care in the nineties, being focused on youth at risk of becoming homeless or young adults being homeless. At the time some of his older colleagues advised him to lower his expectations as to what could be achieved. He continued working, and 10 years later, caught himself being that older colleague telling the younger ones to 'not put their hopes up too high'. After he discovered the Housing First approach, he learnt that his initial hopes of achieving positive outcomes for homeless youth could be realised, and became a Housing First trainer.
