Fisk made her film debut in 1995 as Kristy Thomas in The Baby-Sitters Club. Her next appearance came in the 2000 film Snow Day as Lane Leonard. She is perhaps most well known for her supporting role as Ashley in the 2002 teen comedy Orange County, starring opposite Colin Hanks and Jack Black. Her notable TV appearances include an appearance on One Tree Hill as Daytona in the 2005 episode "I'm Wide Awake, It's Morning", and an appearance on Law & Order: Special Victims Unit as Ella Christiansen in the 2006 episode "Taboo." She played the overbearing and protective sister in the 2011 film Restless.
Fisk plays the guitar, which she learned from her mother, and sang in various musicals as a child. She began writing and playing her own songs at age 15 and, in 2004, signed with Universal Records. In 2006, she put her acting career on hold in favor of honing her skills as a musician and recorded a demo with Joshua Radin, with whom she toured for two years. In early 2006 the duo wrote a song entitled "Paperweight." Radin introduced Fisk to Zach Braff, who in turn used the duet on the Soundtrack of his film The Last Kiss; the song was also included on the Dear John Soundtrack. Various projects soon followed, including recording the song "I Just Remember Goodbye" for the film Gray Matters starring Tom Cavanagh, Heather Graham, and Bridget Moynahan, and "Waking Life" for the film Penelope starring Christina Ricci.
She graduated from the College of Arts & Sciences at the University of Virginia in 2006.
In 2008, Fisk amicably left Universal. Plans to release an EP were scrapped in favor of releasing a full-length album, which was released digitally on January 27, 2009, as a download at several online Retailers. As of the week of February 4, 2009, Fisk's debut album The Good Stuff, climbed to #1 on the iTunes Folk Charts. On Amazon, Fisk's album ranked #17 on the Folk chart in MP3 albums. The album was well received by various media outlets, including the New York Times. She then toured with Ben Taylor.
On March 1, 2011, Fisk released her second album Blue Ribbon Winner (through her label Cassidy Barks), then toured alongside the band Harper Blynn (who collaborated with her on the title track of the album). In November 2011, Fisk released a Christmas EP titled "Sounds of the Holiday" on iTunes and Amazon. Tracks included old classics such as "Have Yourself a Merry Little Christmas," "Rockin Around the Christmas Tree," and "Silver Bells," as well as original Christmas music. Fisk's band FM Radio debuted an album titled Out of the Blue in April 2012.
