Charlie Howard argues that public services should find their users, not wait to be found.

Charlie started the charity MAC-UK to provide specialist mental health services to gang members and other at-risk young people. As she began to work with them, she found more and more people who would never have accessed traditional services, but were in desperate need of them.

She makes the case that this is also a better, more efficient way to help service users, and argues that other public service providers - from teachers to job advisers - should consider how they can adopt the same approach.
