Sonny was the owner of a Boys' Home that was home to a 16-year-old Dean.
Sonny used to hang out with a gang when he was younger. Unfortunately, their lifestyle got them into a correctional facility. Having had a change of heart, he began a boys' home to help troubled young men change their ways before they end up in prison.
Sonny took Dean into his boys' home, wanting to help the young man avoid jail. He gave Dean advice several times and took care of him for about two months. Within the time Dean spent in Sonny's home, the latter came to know about the Winchesters' work.
