Biographical Background

Jo was born in Walla Walla, Washington on July 28.

As a child, Jo was a geeky girl who envied anybody that was popular.

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.[1]

As a teenager, Jo wore braces, and was a fan of Leif Garrett.[2]

Once she had her driver's license, she damaged her father's car by backing into a tree, and let her sister take the blame for it. She finally admitted her part, out of guilt.[3]

When she was a student, her aptitude test suggested a career as a "rock and roll diva, with a world-renowned shoe collection."[4]

​Personal Characteristics

Jo cares deeply about Lizzie but is trying to figure out how to raise a teenager. As a result, she sometimes tends to "mess up" situations in Lizzie's life while trying to make them better. She is very strict and tough on her children. She punishes them a lot. Mostly Matt usually drives her and Sam crazy and mostly why they punish him a lot.

Jo is a big fan of Chinese food.[5]

Jo hates softball.[6]

Romantic Relationships

Jo is married to Sam McGuire. It is indicated several times that they have been married for fifteen years. They first met during freshman week at High School, according to Sam in "Bye Bye Hillridge Junior High". She and Sam were both nerds in high school and both raised their children and is very strict with them.

As a teenager, she had a crush on the lifeguard at the city pool. When she saw him recently, he "lost all his hair, was assistant manager at the local Dairy Freeze, and lived with his mother," according to Jo in "The Greatest Crush of All."
