After an early career in web design, Wilson became a plumber and worked for Roto-Rooter, a large plumbing service company based in Cincinnati, Ohio.

Wilson subsequently admitted that the real reason he wanted to meet Hawes was that he had undergone an intense, recurring paranormal experience beginning at the age of fifteen.

[5] According to his own account, Wilson's recurring experience involved seeing an unidentified entity in the Rhode Island woods on a regular basis.

[8] Wilson, Hawes, and other members of the paranormal community frequently give lectures at schools and paranormal-related conventions.

On the 13th mid-season opener for South Park, Grant and Jason were both parodied and portrayed as easily frightened, going as far as to wet and poop their pants.

In a 2013 interview on British radio,[11] Wilson described some of the scariest cases he had to deal with on Ghost Hunters, including being held by a whole town that practiced black magic.
