Itzin's family moved to Burlington, Wisconsin when he was in sixth grade where his father, Martin Itzin, was a former mayor of the city and, as of 2007, still lives there.

In 2005, Itzin joined the cast of 24, halfway through its fourth season, in the recurring role as Vice President Charles Logan.
