His big break came when Oni Press hired him to illustrate two comic books based on Kevin Smith's movie Clerks from scripts by Smith, following his work on Marvel Comics Generation X Underground Special.

[citation needed] At the age of 18 Mahfood attended the Kansas City Art Institute, where he met Mike Huddleston and formed 40 Oz Comics.

He graduated with a Bachelor of Fine Arts degree in 1997 and went on to produce many comics with his own unique style, heavily influenced by graffiti and underground hip hop culture.

He frequently features his characters wearing T-shirts promoting local or underground hip hop, funk, jazz or punk bands.

Mahfood himself is heavily involved in his local music scene, often doing live mural art during hip hop and DJ events.
