"I guess you can say that."
— Jeff

Jeff was one of two Med-jacks in the Glade, the other being Clint. The two are almost always together. He is a minor character in the book but his role was expanded in the movie. Jeff is most likely named after Thomas Jefferson.


Jeff is most prominently present when Ben is going through the Changing at the beginning of the book, when Teresa arrives, and when Minho, Alby and Thomas are brought back from the Maze alive, as well as any other medical emergency mentioned.

It's unknown whether or not Jeff survived the escape from the Maze or if he made it through The Scorch Trials. But due to the only listed surviving Gladers being Frypan, Minho, Gally, Thomas, and possibly Clint (who was mentioned a few pages before they reached "Paradise" but was not confirmed as reaching it), Jeff must have been killed at some point in the Trials.


In the movie, Jeff is shown to be one of the Gladers that goes with Thomas into the Maze to escape. Shortly after, he is overpowered and killed by Grievers when attempting to save Minho. He is the third to perish in the Griever ambush.

In Maze Runner: The Death Cure, Jeff's name was engraved on the rock along the names of the victims in the war with WCKD.

Physical Appearance and Personality

Jeff is described as being tall with a buzz cut and a nose the size of a fat lemon. He was also shown to be somewhat well built and skinny.
