- First appearance: #1, Horse Crazy.
- Ages: 12, 13 and 14.
- Family: Father, Richard, 42; mother, Eleanor; brother, Peter, 21, who is at college or studying abroad for most of the series; lhasa apso dog named Dolly; step-mom, Evelyn; half sister, Lily; aunt/godmother, Elizabeth; great aunt, Madge.
Lisa`s parents are divorced as of "Stray Horse".
Mr Atwood moves into an apartment so that Lisa can live with him during the weekend until he moves to California.
Evelyn eventually gives birth to a baby girl named Lily before the start of the "Pine Hollow" series.
- Horse(s): Lisa never owns her own horse, although her parents once considered buying her a horse.
In #11, Horse Wise, they view a horse called "Pretty Boy," but Lisa knew she was not ready to own one.
Lisa eventually told Carole Hanson about the horse and she ended up buying him, changing his name to Starlight.
In the Pine Hollow series, Lisa`s father makes plans to buy Prancer for her, a retired thoroughbred racehorse who she rides throughout most of the series.
However, Prancer dies during a difficult pregnancy, as do both of her twin foals, in Riding To Win, the ninth book of the Pine Hollow series.
- Education: The Saddle Club: An 8th grader at Willow Creek Junior High School, the public school she attends with Carole.
Pine Hollow: Senior at Willow Creek High School, the local high school that she and Carole go to.
- Personality: Lisa is the oldest of the three but the newest rider; she begins in #1, Horse Crazy because her mother thinks that every young lady should know something about horses.
She is extremely organized, a straight-A student, and a perfectionist.
Although stable owner, Max, often tells her that she has potential, her desire to "catch up" to Carole and Stevie is an element of most of the series.
Lisa is shorter than Carole and Stevie.
Lisa was named after her Aunt Elizabeth.
- Inconsistencies: Lisa's brother is mentioned peripherally in two early books -- #1, Horse Crazy, in which Lisa's mother wouldn't let Lisa borrow a tie from him, and #7, Horse Play, in which he's at summer camp.
Since Peter is eight years older than Lisa and living away from home for the rest of the series, it is likely that these are errors.
- Disasters: In the 25th episode "Bridle Path: Part 1", she falls off Prancer after she tries to have Prancer jump the highest obstacle to practice for the Oakridge on Saturday and is diagnosed with a concussion.
