Do some clinical child psychologists work outside of the office?

I remember being a mentor of an abused boy, and just hanging out and talking really influenced the kid's life and his grades improved. I think my future career in psychology and working in an office setting would be kinda scary since it feels trapped for a child. If you remember "The Sixth Sense" the psychologist was outside of his office and went to the house, etc. He was like a mentor but a trained child psychologist as well. Of course, that's just fiction, but I had a good sense of its effectiveness while mentoring before. Any thought on that?
