Unlike performers who enter Hollywood during adulthood, Agudong began developing her career at a young age. She secured an early professional role when she was approximately eight years old, giving her experience in television production long before her major Netflix appearances.
By her teenage years, she had already participated in several television productions and started taking on increasingly prominent roles.
Her early career demonstrates how child performers can gradually transition into more complex characters as they grow older.
Early Life and Education
Siena Agudong was born and raised on Kauai, one of Hawaii’s islands known for its natural landscapes and outdoor lifestyle.
Growing up in Hawaii played an important role in shaping her interests. Beyond acting, she has expressed an interest in surfing, hiking, and ocean conservation, particularly efforts involving coral reef restoration.
Although she became involved in entertainment at an early age, detailed public information about her formal schooling is limited. Specific claims about her school or college education should therefore be treated cautiously unless supported by reliable sources.
How Siena Agudong Started Acting
Agudong began her professional career in 2013 when she landed a recurring role in the ABC television drama Killer Women.
That opportunity introduced her to professional television production and was followed by appearances in other established series.
She subsequently worked on Teachers and Nickelodeon’s Nicky, Ricky, Dicky & Dawn, gaining experience in both comedy and drama.
Her early acting credits helped establish the foundation for the leading roles that followed.
By 2018, she was appearing in projects designed for young audiences, including Star Falls and the soccer-themed film Alex & Me.
These experiences marked her transition from supporting television appearances to more substantial roles.
Siena Agudong’s Parents, Family, and Sister
Siena Agudong was born to Karen Agudong and Kenneth Agudong. Her family background is connected to Hawaii, where she spent her childhood.
Although her parents are identified in public biographical records, detailed information about their professional lives remains limited.
Agudong has generally kept much of her family life outside the entertainment spotlight, allowing her acting projects to remain the main focus of public attention.
Who Is Siena Agudong’s Sister?
Siena’s sister, Sydney Agudong, is also an actress and performer.
Sydney received widespread attention for portraying Nani in Disney’s live-action adaptation of Lilo & Stitch, released in May 2025. The film features Maia Kealoha as Lilo, with Sydney portraying her protective older sister.
Although the sisters share a family background and entertainment careers, their professional credits are different.
Siena is particularly recognizable for No Good Nick, Resident Evil, and Sidelined, while Sydney is prominently associated with Lilo & Stitch.
Their respective acting careers also demonstrate the growing visibility of performers from Hawaii in mainstream American entertainment.
Siena Agudong’s Acting Career and Rise to Fame
Siena Agudong’s career has developed through a mixture of television comedies, family movies, streaming dramas, and horror productions.
Her major roles have allowed her to portray characters with different personalities, motivations, and emotional challenges.
Early Television Roles and Star Falls
One of Agudong’s earliest significant leading television roles came in the 2018 Nickelodeon series Star Falls.
She portrayed Sophia Miller, a teenager whose life changes when a famous Hollywood actor and his family become part of her small-town world.
The series combined family comedy with everyday teenage experiences, making it a natural fit for Nickelodeon’s younger audience.
For Agudong, Star Falls offered an opportunity to carry a major storyline and develop her screen presence beyond smaller guest appearances.
She also appeared in Alex & Me (2018), a family sports film featuring soccer star Alex Morgan.
Together, these projects strengthened her association with youth-oriented entertainment.
Breakthrough With Netflix’s No Good Nick
Agudong gained greater recognition in 2019 when she starred as Nicole “Nick” Franzelli in Netflix’s No Good Nick.
The comedy-drama follows a teenage girl who enters the Thompson family’s household while secretly pursuing her own agenda.
Her character presents herself as a vulnerable teenager, but the situation becomes complicated as personal motivations and genuine emotional connections begin to overlap.
The cast includes Melissa Joan Hart, Sean Astin, Lauren Lindsey Donzis, and Kalama Epstein.
Playing Nick required Agudong to move between humor, deception, vulnerability, and emotional conflict.
The role remains one of her most recognizable television performances and helped introduce her to an international streaming audience.
Siena Agudong in Resident Evil
In 2022, Agudong appeared in Netflix’s live-action Resident Evil series, portraying the younger version of Billie Wesker.
The series draws inspiration from the popular video game franchise and explores a world threatened by dangerous experiments and biological disasters.
Billie is the daughter of Albert Wesker, portrayed by Lance Reddick. Her relationship with her sister Jade forms an important part of the story’s emotional foundation.
Unlike the lighter tone of Star Falls and No Good Nick, Resident Evil placed Agudong in a darker science-fiction and horror setting.
This provided an opportunity to demonstrate her ability to work across different genres.
Sidelined: The QB and Me and Its Sequel
Agudong played Dallas Bryan in Sidelined: The QB and Me, a romantic drama released on Tubi in November 2024.
The film follows Dallas, an ambitious dancer, and Drayton Lahey, a talented football player portrayed by Noah Beck.
Their relationship develops as both characters navigate personal ambitions, emotional challenges, and expectations about their futures.
The movie draws on the popularity of young-adult romance stories and was adapted from Tay Marley’s Wattpad novel The QB Bad Boy and Me.
Following the first film’s success, Tubi announced a sequel featuring Agudong and Beck returning as Dallas and Drayton.
Sidelined 2: Intercepted premiered on November 27, 2025.
The sequel explores the pressures of college, distance, and personal change as the two characters question their plans and relationship.
Agudong was also credited as an executive producer on the sequel, representing an expansion of her professional responsibilities beyond acting.
Siena Agudong in Carrie (2026)
One of Agudong’s notable recent projects is Carrie, the Prime Video television adaptation of Stephen King’s famous horror novel.
The series was developed by filmmaker Mike Flanagan.
Agudong plays Sue Snell, a significant character in the story surrounding Carrie White, a bullied teenager who develops extraordinary telekinetic abilities.
Summer H. Howell portrays Carrie White, while the ensemble also includes Samantha Sloyan, Matthew Lillard, Alison Thornton, and Joel Oulette.
The adaptation explores teenage cruelty, social pressure, and the consequences of bullying through a contemporary perspective.
For Agudong, the series represents another substantial horror role following her work in Resident Evil.

How Tall Is Siena Agudong?
Siena Agudong is approximately 5 feet 3 inches (160 centimeters) tall, according to her professional acting résumé.
Height is a frequently searched celebrity detail, particularly for actors appearing alongside different co-stars.

Her career achievements are better understood through her screen performances, production experience, and range of characters.
Is Siena Agudong Dating Anyone?
Siena Agudong has attracted interest from fans curious about her romantic relationships, particularly following her performances in young-adult romance productions.

On-screen relationships should not be confused with real-life partnerships. Her romantic storyline with Noah Beck in Sidelined: The QB and Me, for example, is part of the film’s fictional narrative.
Without a recent public confirmation from Agudong or dependable reporting, it would be misleading to identify someone as her current boyfriend.
