Christopher Kimbrell is one of the pre-made NPC coaches in La Fiesta Tech from The Sims 2: University. He can be made playable by befriending and asking him to move in, or by marrying him. Like all coaches in University, Christopher has 10 active points.
Christopher has the same facial structure as Aiden Reamon. According to his SimDNA in SimPE, his hair was red before it turned grey.
Christopher's name is randomized when La Fiesta Tech is generated. The name "Christopher Kimbrell" is only referenced in the game files.
Even though Christopher is thin, his fitness level indicates that he is supposed to be fit. This happens with all coaches from The Sims 2.
