Josephine Lynn "Jo" McGuire was Lizzie and Matt's mother. She cared deeply about Lizzie but was still trying to figure out how to raise a teenager. As a result, she sometimes tended to "mess up" situations in Lizzie's life while trying to help make them better. At the end of each episode, Jo and Lizzie tend to come to an understanding and portray the unfaltering love of a mother-daughter relationship. Her birthday is July 28.
It is stated in many episodes that Jo, as a child, was a geeky girl who envied anybody that was popular. She treasured her record and CD collections (including Leif Garrett vinyl records). In the Season 1 episode "Between a Rock and a Bra Place", she said that when she was thirteen and her mother took her shopping, her mother would do everything she could to embarrass Jo. Jo promised herself that she would never act that like that with her own daughter. After Lizzie told her that she didn't act that way with her, Jo agreed and said that she was worse.
It is revealed that she was born in Walla Walla, Washington.
