When a person grows up with a famous parent, it is easy for the public to define them by their family connection. That is certainly part of the story surrounding Oona Gray Seppala, who is widely known as the daughter of Suits actress Sarah Rafferty. But looking beyond the celebrity connection reveals a more interesting picture.
Oona Gray Seppala has developed her own interests and accomplishments, particularly through student journalism. Her biographical story goes beyond her connection to actress Sarah Rafferty. During her time at The Archer School for Girls, she became involved with the school’s student newspaper, The Oracle, eventually progressing through several editorial positions before becoming Editor-in-Chief. Her school profile also identifies her involvement in varsity tennis, a cappella, community service and a service organization she founded.
This makes the story of Oona Gray Seppala less about being a celebrity child and more about how she has built an identity of her own while growing up in a family connected to the entertainment industry.

PEOPLE reports that Oona was born on October 22, 2007, to Sarah Rafferty and Santtu Seppälä. The same source identifies her as the couple’s eldest daughter and notes that her younger sister, Iris Friday Seppälä, was born in 2012.
Who Is Oona Gray Seppala?
Oona Gray Seppala is the eldest daughter of actress Sarah Rafferty and Finnish-American financial professional Santtu Seppälä. Her mother’s career gave the family a connection to Hollywood, particularly through Rafferty’s long-running role as Donna Paulsen on Suits. Yet Oona has largely remained outside the entertainment spotlight.
Instead of establishing herself as a conventional celebrity, Oona’s most clearly documented public work comes from her school journalism career. Her profile at The Oracle states that she joined the publication in 2022, became a senior reporter in 2023, moved into the multimedia editor role in 2024 and became Editor-in-Chief in 2025.
That progression is significant because it demonstrates that her public identity is not based solely on her mother’s fame. She has spent several years developing skills in reporting, editing, multimedia production and editorial leadership.
Oona Gray Seppala Age and Birthday
One of the most frequently searched details about Oona Gray Seppala is her age.
Oona was born on October 22, 2007. PEOPLE reported her birth date while profiling Sarah Rafferty’s two daughters. As of August 2026, Oona is 18 years old and will turn 19 in October 2026.
There are conflicting birth dates published on some low-quality biography websites. Because those sites often repeat information without identifying an original source, the October 22, 2007 date reported by PEOPLE is the safer date to use in a professionally researched biography.
Oona Gray Seppala Parents
Oona’s parents are Sarah Rafferty and Santtu Seppälä.
Sarah Rafferty is an American actress best known internationally for portraying Donna Paulsen on Suits. Her television career has included numerous other appearances, but her role on Suits remains the performance most closely associated with her name.
Santtu Seppälä is a Finnish-American financial professional. The couple married in 2001 and later welcomed two daughters, Oona and Iris. PEOPLE reports that Oona was born in 2007 and Iris in 2012.
For Oona, having an actress for a mother meant that entertainment was part of her childhood environment, but that did not necessarily translate into a professional entertainment career of her own.
Oona Gray Seppala and Sarah Rafferty
The relationship between Oona Gray Seppala and Sarah Rafferty has attracted public interest because of Rafferty’s popularity.
Sarah Rafferty has spoken positively about motherhood and her relationship with her daughters. PEOPLE reports that Rafferty has emphasized maintaining an open and honest relationship with Oona and Iris and creating a family environment in which her daughters could communicate freely.
During the years when Suits was being filmed in Toronto, the family experienced a bi-coastal lifestyle between Los Angeles and Toronto. According to Rafferty’s comments reported by PEOPLE, Oona attended two different schools during that period.
The experience gave Oona a childhood that was somewhat different from that of many children, but her mother’s celebrity status does not appear to have become the defining feature of Oona’s own public activities.
Oona Gray Seppala Sister
Oona has one younger sister, Iris Friday Seppälä.
Iris was born in January 2012, making her several years younger than Oona. Sarah Rafferty has spoken about the close relationship between her daughters and the importance of empathy and family connection while raising them.
Interestingly, Oona has also written about being a big sister. One of her Oracle articles, published in 2023, was titled “Being a big sister made me a better leader.” The article provides a personal perspective on how her relationship with her younger sister influenced her understanding of responsibility and leadership.
Oona Gray Seppala Education
Education is another important part of the Oona Gray Seppala biography.
Oona attended The Archer School for Girls, a girls’ school in Los Angeles. Her involvement with the school’s student newspaper became one of the most significant documented parts of her public profile.
Rather than simply contributing occasionally, Oona progressed through increasingly responsible positions at The Oracle. Her official staff profile records a clear timeline: she joined the publication in 2022, became a senior reporter in 2023, served as multimedia editor in 2024 and became Editor-in-Chief in 2025.
That progression suggests a sustained interest in journalism rather than a short-term extracurricular activity.
Oona Gray Seppala and The Oracle
The strongest source for understanding Oona’s own interests is The Oracle, Archer’s student publication.
Her author profile contains a substantial collection of articles covering subjects ranging from entertainment and school life to technology, sports, culture and social issues. In 2025, her bylines included pieces about Netflix’s Adolescence, school mathematics support, grocery-store tourism and internship opportunities.
Her work demonstrates several different sides of journalism. Some pieces are reviews, while others involve interviews, commentary, reporting or multimedia storytelling.
This is important when discussing Oona Gray Seppala career because it would be inaccurate to portray her as an established Hollywood actress when the strongest available evidence instead documents her development as a student journalist.
Oona Gray Seppala as Editor-in-Chief
Becoming Editor-in-Chief was arguably one of the most notable accomplishments in Oona’s documented student career.
By 2025, she was serving as Editor-in-Chief of The Oracle. Her work included not only writing stories but also participating in the editorial process and helping lead the publication.
A 2025 Oracle article describes Oona and fellow Editor-in-Chief Emily Paschall working together to lead the newspaper staff. The publication’s archive also contains numerous articles written by Oona in her Editor-in-Chief role.
For someone searching for Oona Gray Seppala biography, this may be the most useful detail to understand: her documented achievements show a young person developing leadership through journalism rather than relying on a famous family name.
Oona Gray Seppala Journalism Work
Oona has written about a surprisingly broad range of subjects.
Her published work includes entertainment reviews, school news, opinion pieces, interviews, multimedia projects and cultural commentary. Among her work are reviews of Daisy Jones & The Six, Ed Sheeran’s Mathematics Tour, Exit West, Mac Miller’s Balloonerism and Netflix’s Adolescence.
She has also covered topics including TikTok, tennis, student life, education and community issues.
One particularly interesting piece is her commentary about deleting TikTok, which combined personal experience with broader observations about social media. Her work on The Oracle shows that she has explored both personal and journalistic forms of writing.
Oona Gray Seppala Journalism Recognition
Oona’s journalism work has also received recognition beyond simply appearing in her school newspaper.
Archer’s school information has highlighted recognition for Oona’s journalism work, including an Honorable Mention in the National Scholastic Press Association’s Spring 2025 Clips & Clicks contest for her review of Mac Miller’s Balloonerism.
That recognition provides an independent indicator that her writing has attracted attention within the student journalism community.
Oona Gray Seppala Tennis
Journalism is not Oona’s only documented interest.
Her official Oracle profile states that she plays on the varsity tennis team at The Archer School for Girls. It also lists her participation in Archer’s a cappella group and Service Squad.
Her involvement in athletics adds another dimension to her profile. Rather than focusing exclusively on academics or journalism, she has participated in school activities that involve teamwork, performance and competition.
Oona Gray Seppala A Cappella and Creative Interests
Oona is also a member of Archer’s a cappella group, according to her school newspaper profile.
Her journalism work demonstrates another creative interest: multimedia storytelling.
Some of her published pieces include graphic illustrations and multimedia components. Her Oracle profile therefore presents a combination of writing, editing, visual creativity and communication.
These documented interests are a better foundation for describing Oona’s creative side than unsupported claims that she has already established herself as a professional actress or singer.
Oona Gray Seppala Service Work
Community involvement is another part of Oona’s school profile.
According to The Oracle, she founded a service organization called Rhythms for Residents and participates in Archer’s Service Squad. Her profile also says that she enjoys volunteering.
This aspect of her background helps broaden the Oona Gray Seppala story beyond entertainment and journalism.
Her activities suggest an interest in combining communication and creativity with community involvement.
Did Oona Gray Seppala Become an Actress?
This is an important question because some websites describe Oona as an actress, singer or dancer.
However, those descriptions should be treated cautiously.
The strongest sources available for Oona document her as a student journalist, editor, athlete, service participant and member of an a cappella group. Her Oracle profile contains an extensive record of her journalism work, but it does not establish a professional acting career.
Therefore, it is more accurate to say that Oona has grown up around the entertainment industry through her mother while pursuing her own documented interests.
Calling her a professional Hollywood actress without reliable evidence would give readers a misleading impression.
Oona Gray Seppala Personal Life
Despite having a famous mother, Oona has maintained a relatively private personal life.
Most reliable information about her comes from her school activities and occasional comments from Sarah Rafferty. She does not appear to have pursued the same kind of public celebrity profile as her mother.
That privacy is significant. In an era when celebrity children can quickly become social-media personalities, Oona’s documented path has been comparatively focused on education, journalism, extracurricular activities and family.
Oona Gray Seppala Social Media
Another frequently searched topic is Oona Gray Seppala Instagram.
There are online pages that associate different social-media accounts with Oona, but an account should not automatically be treated as official simply because it uses her name.
Because Oona has maintained a relatively private public profile, it is better not to publish an unverified social-media account as her official profile.
Her public work through The Oracle provides much stronger evidence of her activities and interests.
Oona Gray Seppala Net Worth
There is no reliable public figure for Oona Gray Seppala net worth.
Some celebrity-biography websites publish numerical estimates for the finances of celebrity children, but these figures are generally unsupported and should not be treated as factual.
Oona is still young, and her documented public profile is primarily connected to education and student journalism rather than a commercial entertainment career. As a result, assigning a specific personal net-worth figure would be speculative.
Her family’s financial circumstances should also not be confused with her own personal wealth.
What Makes Oona Gray Seppala Interesting?
The most interesting part of the Oona Gray Seppala story is the contrast between her family background and her own activities.
Her mother is a recognizable television actress. Oona, however, has built a documented record in an entirely different area: journalism.
She progressed from reporter to senior reporter, then multimedia editor and ultimately Editor-in-Chief. She also participated in varsity tennis, a cappella and service activities.
That combination makes her story more nuanced than a typical celebrity-child biography.
Life Beyond Her Mother’s Fame
Growing up as the daughter of a recognizable actress could easily have placed Oona in the center of public attention. Instead, the available evidence shows someone who has largely developed her own interests away from mainstream celebrity culture.
Her journalism work is particularly revealing. Through The Oracle, she has written about subjects that matter to students and broader audiences, while also taking on editorial responsibilities.
Her journey illustrates how a person can grow up in a famous family without necessarily making celebrity the center of their own identity.

Yes, Oona grew up as the daughter of Sarah Rafferty, an actress recognized around the world for Suits. She experienced a childhood that included visits to television sets and a family life shaped partly by her mother’s career.
