Prior to her first acting gig, Schull trained as a ballerina. She was born in Hawaii and started her dance training there, before studying at Indiana University and then the San Francisco Ballet School. Schull's first acting role was in a ballet-based coming-of-age film, "Center Stage" (2000). Schull danced with the San Francisco Ballet until 2006 and then returned to acting for various TV and movie roles.
One of her notable, recognizable TV roles is from the show "One Tree Hill," where she portrayed two characters: Sara Evans and Katie Ryan, both connected to character Clay.
After her 12-episode arc on "One Tree Hill," Schull had guest roles on shows such as "Hawaii Five-0," "Castle," "Psych," "Grimm," and "The Mentalist." She also had a role in "J. Edgar," a movie starring Leonardo DiCaprio and directed by Clint Eastwood. In the show "Pretty Little Liars," she played Meredith Sorenson — an antagonist to the character Aria Montgomery due to Meredith's relationship with Aria's father. (Ian Harding, another "Pretty Little Liars" actor, also ended up on Hallmark screens in 2022's "Ghosts of Christmas Always.")
