Jeff is a sixth grader who attends P.S. 38. He was described to be unattractive by Nate Wright saying that if Jeff could find a girlfriend, so can he. His Thanksgiving leftovers he had for school lunch were also displeasing to Nate which were vegetables, fruits, and tofu, as he asked Sheila Stapleton to remind him to never attend a holiday celebration at Jeff's house. Once, Nate asked him if he wants to be the first member of his posse. Jeff got worried because he thought he had to be hazed to join the posse.
When Nate lost his lucky socks, Jeff returned them, but to Nate's shock, he washed them, which Nate thought washed the luck off. Nate once told him to give a note to Angie, but instead he gave it to Andy.
At one point, he also played football with Nate and his friends.
