Troian Bellisario Bio
Troian Avery Bellisario (born October 28, 1985) is an American actress and filmmaker whose work spans television, feature film, and short-form storytelling. She is best known for her portrayal of Spencer Hastings in the Freeform drama series Pretty Little Liars, a role she played from 2010 to 2017 that brought her international attention. Beyond acting, she has built a parallel career as a writer, director, and producer, often drawing on personal experience to shape her projects. As the daughter of two television industry figures, she grew up close to the craft and has continued to expand her footprint across the entertainment world.
Early Life and Background
Troian Avery Bellisario was born and raised in Los Angeles, California, the daughter of producer Donald P. Bellisario and producer and actress Deborah Pratt. Her father is the creator of long-running series including Magnum, P.I., Quantum Leap, and NCIS, and her mother also worked in television, giving Bellisario early exposure to set life and storytelling. She has a younger brother, three half-sisters, two half-brothers, and two stepbrothers, including actor Sean Murray and producer Chad W. Murray. Her father is of Italian and Serbian descent, and her mother is of African American descent.
Bellisario attended Campbell Hall School in Studio City, California, from kindergarten through twelfth grade, where she graduated at the top of her class. After high school, she enrolled at Vassar College but took a break after several months, citing concerns that the environment intensified her perfectionist tendencies and affected her mental health. She later completed her studies at the University of Southern California, earning a Bachelor of Fine Arts degree in 2009. In 2014, she returned to the USC School of Dramatic Arts to deliver its commencement address.
Path to Acting
Bellisario made her acting debut at the age of three in the 1988 film Last Rites, a project directed, written, and produced by her father, Donald P. Bellisario. In 1990, she guest-starred in an episode of her father’s series Quantum Leap, gaining further early on-camera experience. As a child performer, she co-starred with Mary-Kate and Ashley Olsen in the 1998 film Billboard Dad, which introduced her to a wider audience. These early appearances, set against the backdrop of her family’s television career, helped her understand production from the inside out.
Beginning in 2006, Bellisario took on a series of independent short films, including Unspoken, Archer House, and Intersect, which allowed her to develop her craft outside the family business. She met actor Patrick J. Adams in 2009 while working on the play Equivocation, and the collaboration marked the beginning of both a personal and professional partnership. Together they would later work on Pretty Little Liars, Suits, and several short films, including We Are Here, which the pair filmed in Haida Gwaii.
Troian Bellisario Career
Early Career (1988–2009)
Bellisario’s earliest credits came through her father’s productions, beginning with Last Rites in 1988 and a guest role on Quantum Leap in 1990. Her turn in Billboard Dad in 1998 gave her a foothold in family entertainment and showed her comfort in front of the camera. During this period she balanced schoolwork with small auditions, eventually shifting toward more artist-driven short films in the mid-2000s.
Her time at Vassar College and later at the University of Southern California shaped her approach to the craft and led her toward a more disciplined, independent path. By the time she completed her BFA in 2009, she had accumulated a varied résumé of child, teen, and young-adult roles, and she was ready to pursue larger projects on her own terms.
Breakthrough (2010–2017)
In November 2009, Bellisario was cast as Spencer Hastings in the Freeform drama Pretty Little Liars, based on the book series of the same name by Sara Shepard. The series premiered in 2010 and ran until 2017, and her performance as the brilliant, tightly wound Hastings became her defining role, earning her international recognition. In October 2011, while still working on the show, she announced she was writing and creating her own film, which was successfully funded through Kickstarter on November 16, 2011. Filming wrapped in December 2011, and the project was officially completed by August 2012.
During this period, she expanded into feature film, starring in C.O.G. (2013), a drama based on a David Sedaris essay, and in the music video for The Head and the Heart’s song Another Story in 2014. In 2015, she was cast in a leading role in the American remake of the French-Canadian film Martyrs, and the following year she co-starred with Australian actress Jacki Weaver in the television drama film Sister Cities (2016). She also starred opposite Bradley Whitford in the web series Lauren (2012–2013) and made a brief return to her father’s world with the short film We Are Here, which she wrote and starred in alongside Adams.
In 2017, Bellisario starred in the feature film Feed, which she also wrote and produced. The film drew directly on her own experiences with an eating disorder, giving her one of her most personal projects to date. On April 7, 2016, it was announced that she would be directing season 7, episode 15 of Pretty Little Liars, making her one of the first members of the cast, alongside Chad Lowe, to helm an episode of the series. In 2020, she appeared in Stumptown, playing the bride character Jenna Marshall in the episode Til Dex Do Us Part.
