| ||For the former employee of L.O.B. Enterprises mentioned in Fallout 3, see Johansson.|
Doc Johanson or Doc J was the doctor of a small commune who lived at the Hilltop Farm ruins.
He was responsible for keeping the group alive and well after they emerged from their unspecified shelter and provided regular radiation checkups.
Doc Johanson does not actually appear in any game but terminal entries from and about him can be found in a terminal at Hilltop Farm ruins in Fallout 3.
