List of United States of Tara characters

The list of United States of Tara characters centers on the Gregson family. The series follows the family as it deals with Tara Gregson and her struggles with dissociative identity disorder. Her family, including husband Max, children Kate and Marshall, and sister Charmaine, serve as her support system. Secondary characters include love interests, neighbors, friends, and Tara's therapists. Tara's "alters", or alternate personalities, stand as characters in their own rights and continually interact with the other characters and sometimes with each other and Tara.
