Although probably best known for his recurring role as the mean history teacher, Mr. Stern, on Nickelodeon's "iCarly," Joseph's roles run the gamut from psychiatrists to psychopaths. Specializing in dry-witted characters that could snap at any moment, Joseph admits he enjoys playing the type of people that, "you know something's off with them, but you're not quite sure what...and it drives you crazy!" If you're looking for a nervous accountant who just might also be a serial killer, Joseph Buttler's body of work speaks for itself.
