J.B. has spent all of her life in libraries, labs and garages, and she has mad skills in all things scientific, technical and mechanical. J.B. enjoys being the brains behind the local ghost-hunting operation, app, and all the gang’s ghost-hunting gear, while leaving all the messy work to the kids (Hey, they don’t seem to mind.) She eats, works and sleeps in her messy lab, except when she’s driving ‘Sweet Sally’, her old decked-out school bus. Also, she drinks waaay too much coffee.
