Maddie is the teenage candy counter girl at The Tipton Hotel, a cashier at the Cluck Bucket, manager of the Camp Tipton Daycare Center, at a counselor for her school's summer camp program.
The Suite Life of Zack & Cody
Maddie began working at the Tipton to gain money for her family. She is fairly smart, and works at the candy counter. She works through several jobs, including as a cashier and a daycare sitter. After a while, London begins to go to Catholic school with her.
The Suite Life on Deck
Maddie saves up her tips, babysitting money, and change behind the couch, and bought a bus ticket. London then paid for Maddie to come aboard the S.S Tipton, where she then was "engaged" to the 7-year-old Prince Jeffy, but was won in a joust by Zack in the episode "Maddie on Deck". This is her last Suite Life appearance.
Though Maddie is described as being from a poor family, she is still very nice, though sarcastic at times, and has times where she gets irritable. She seems to care about others and she is extremely hard-working.
As a student
Maddie was a student in Our Lady of Perpetual Sorrow, with Corrie & Mary-Margaret, since she told in Forever Plaid, she ever was a "Perfect Student", but when London & she go to detention, she breaks her perfection. Later, she entered Cheevers High School, with Zack, Cody, London and Nia.
As an employee
Since she was 15, Maddie was the Tipton's Candy-Girl, because her family was poor. She lives very near the Tipton, & she has double-turn hour when her parents need a travel for many specials days (a.k.a. Anniversary, Birthdays, etc.) In the Tipton, she also works in the Camp Tipton Daycare Center, in Day Care, she escaped of the kids because her brother was playing with her grandma. Also, in Nugget Of History, she also is an employee in the Cluck Bucket, as she, she starts as "Hilary Chicken", but later she was a cook. In the summer, she was a counselor in Camp Heaven on Earth (in Summer of Our Discontent), for the school, and she re-met with Holly (the conning girl of Have a Nice Trip), and Jasmine, Amy, and Leah (a girl who needs to go to anger management, a stealer and a liar, and a quiet but aggressive girl).
She is very smart, and was a perfect student of Our Lady of Perpetual Sorrow. She is also shown to be smarter than London. However, London beats her in chess in Smart & Smarterer.
Singing and Dance
She is a great singer, as it was shown in Commercial Breaks, when she sings Shoo-Bop-Bop (with Zack). Also in Season 1, she was the singer of Lance's band Waterworks in Band in Boston. Later, she danced & sung great in Lip Synchin' in the Rain, when in her audition she sings Bop to the Top, but at final, London was the star, and Maddie the voice. But in the end, Zack helps her to enter in the show, and she sings "Bop to the Top" with London.
Health and Fitness
She wasn't doing too well in Physical Education, and London helped her in Dad's Back. Later, in Health & Fitness, she thinks she's very thin, and she starts to eat more to gain weight.
She mostly wears her Tipton Uniform, because she works at the Tipton Hotel. Also she said her family told her she looks exactly the same as "Sharpay" of "High School Musical" (a character whom Ashley Tisdale also portrayed). Also, in the High School Musical Show in her school, she said she is similar to Ashley Tisdale.
