Vanessa Marano began acting professionally when she was seven years old. According to an interview with her sister, her mother did not want either of her children to have careers in show business, and took the girls to an agent that she believed was most likely to turn kids down, only to find that Vanessa was accepted. Her sister Laura, who was on the scene with her, also impressed the agency. Since then, she worked for productions at the Stage Door Theater. Vanessa's first major roles on television have been as Jack Malone's older daughter in Without a Trace (she and real life sister Laura play sisters), Valerie's stepdaughter in The Comeback and as April Nardini in Gilmore Girls. She also played Layne Abeley in The Clique based on the books by Lisi Harrison and Samantha Combs in Dear Lemon Lima. Marano starred in an episode of Ghost Whisperer alongside Jennifer Love Hewitt. Marano played Eden on The Young and the Restless and Hope on Scoundrels. Since June 2011, she has starred as Bay Kennish on the ABC Family TV show Switched at Birth. In 2013, she starred in Restless Virgins which was inspired by a true story.
