Oona Gray Seppala: The Untold Truth about Growing Up a “Suits” Star’s Kid
Have you ever wondered what it is really like to be the child of a television icon? You might picture red carpets and glamorous parties. But for Oona Gray Seppala, the reality is much quieter and surprisingly relatable. While her mother, Sarah Rafferty, stole hearts as the brilliant Donna Paulsen on the hit show Suits, Oona has been living a life that prioritizes books over spotlights and hiking trails over Hollywood boulevards. If you are a fan of the show or just curious about how celebrity families manage to stay grounded, you are in for a treat.
In this article, we are going to peel back the curtain on Oona Gray Seppala. I have gathered all the available information to paint a picture of who she is, how she was raised, and why she represents a refreshing change from the typical “nepo baby” narrative. We will look at her tight knit family, her Finnish American roots, and how her famous parents have successfully shielded her from the pressures of fame. By the end, you will understand why this young woman is much more than just the daughter of a Suits star.
Who Exactly is Oona Gray Seppala?
Let’s start with the basics. You might not recognize her face, and that is entirely by design. Oona Gray Seppala is the eldest daughter of actress Sarah Rafferty and her husband, Santtu Seppälä. She was born on October 22, 2007. That makes her a Libra, if you are into zodiac signs, and currently in her late teens navigating the bridge between high school and adulthood.
Unlike many celebrity kids who seek out Instagram fame, Oona has remained largely invisible on social media. Her parents have worked hard to keep her life private. In fact, when Sarah Rafferty posts birthday tributes to her daughter, she almost always hides Oona’s face, showing only a smile from the chin down or using clever angles. This isn’t about being secretive. It is about giving her daughter a choice. Oona didn’t ask to be in the public eye, so her parents have ensured she doesn’t have to be until she is ready.
The Powerhouse Parents Behind the Privacy
To understand Oona, you have to understand the environment she was raised in. It is a unique blend of artistic passion and financial acumen.
Sarah Rafferty: More than Donna Paulsen
Of course, you know her mother. Sarah Rafferty is beloved for her quick wit and loyalty on Suits, but off screen, she is a Yale School of Drama graduate who takes parenting very seriously. Sarah has spoken about how she focuses on “embracing the chaos” rather than trying to achieve a perfect balance. She wants her daughters to know they can talk to her about anything.
What I find interesting is that Sarah intentionally kept Oona close during the Suits years. The family lived a bicoastal life between Los Angeles and Toronto, where the show was filmed. Instead of seeing this as disruptive, Oona adapted. Her mom once mentioned that the experience ended up being “amazing and self esteem building” for her daughter because she learned to adapt to new environments quickly.
Santtu Seppälä: The Financial Genius Dad
Then there is dad. Santtu Seppälä is not an actor. He is a Finnish American businessman and investor with an Ivy League pedigree, holding degrees from Yale and Wharton. He works in venture capital and strategy. This dual parent dynamic is fascinating. While mom teaches her about creativity and performance, dad provides a massive dose of stability and intellect. He is the anchor that keeps the family rooted in reality. Growing up, Oona witnessed her mother’s fame, but she went home to a father who valued spreadsheets and logic just as much as scripts.
A Childhood Spent on the Suits Set
Imagine growing up with “Aunt Meghan” before she was a duchess. Oona Gray Seppala spent a significant part of her childhood on the set of Suits. For a young child, a television studio is basically a giant playground.
According to interviews, Oona and her younger sister Iris loved visiting the set. Their favorite spots? The craft services table (obviously, free snacks are a win at any age) and the hair and makeup trailers. Sarah Rafferty once shared that her girls loved getting dressed up in the “outrageously gorgeous couture” from the wardrobe room. It is a sweet image—a little girl playing dress up with Donna Paulsen’s high heels while her mom rehearses lines.
One of the most notable public appearances for Oona came in 2018. She traveled to London with her family to attend the royal wedding of Meghan Markle and Prince Harry. This was a rare moment where the world got a glimpse of her. Walking through the streets of London, she looked poised and curious, taking in the chaos of a global event with her family by her side.
The Sister Bond: Oona and Iris Friday
You cannot talk about Oona without mentioning her younger sister, Iris Friday Seppälä. Born in 2012, Iris is the baby of the family. Every indication we have points to a very close, loving sibling relationship.
In a world where siblings fight over the remote control, these two seem to have a genuine friendship. A specific story from Thanksgiving a few years back really highlights this warmth. Iris wrote a letter saying she was thankful for her sister because “she gives me a napkin when my ice cream drips”. It is such a small, specific detail, but it tells you everything you need to know about Oona’s character. She is the responsible big sister, the one who cleans up the messes and looks out for the little one.
The Finnish American Identity
One aspect that sets Oona apart is her heritage. Thanks to her father, she has a strong connection to Finland. The family embraces “Sisu,” a Finnish concept that represents grit, resilience, and determination. This isn’t just a buzzword for them; it is a lifestyle.
Growing up, Oona has likely experienced cold Nordic winters and understands a culture that values humility and silence over boasting. This is a stark contrast to the loud, self promoting nature of Hollywood. I think this cultural mix has given her a unique worldview. She gets the ambition and drive of the United States, but also the understated strength and love for nature typical of Scandinavia. It is the perfect recipe for a well rounded individual.
Keeping Life Private in a Digital World
We live in an era of oversharing. Many parents turn their children into content. Sarah Rafferty and Santtu Seppälä have done the exact opposite. They have built a fortress of privacy around Oona Gray Seppala.
Why is this so effective? It is because they are consistent. Sarah shares glimpses of her life—like hiking trips in Arizona or bike riding in Paris—but Oona is usually facing away from the camera or is a tiny figure in the distance. The message is clear: we are a family, we have fun, but our faces are ours to share when we are ready. As of now, Oona does not have public social media accounts. In a world of influencers, choosing silence is a powerful act of self possession.
What Does the Future Hold?
As of 2025, Oona is 18 years old. She is at a fascinating crossroads. Will she follow her mother into acting? Or her father into finance? Or will she forge a completely different path in the arts or sciences?
We don’t know the answer yet, and honestly, that is exciting.
Given her parents’ emphasis on education, it is highly likely that Oona will pursue higher education. Both parents are Ivy Leaguers, so the academic bar is set high. However, Sarah Rafferty has mentioned she hopes her daughter feels “confident because she feels deeply connected to her family”. Whether Oona ends up on a stage, in a boardroom, or in a classroom teaching, she seems to have the emotional tools to succeed. She is grounded, smart, and protected from the “dark side” of Hollywood that eats up so many young stars.
Conclusion
Oona Gray Seppala is a rare gem in the celebrity landscape. She is proof that not all famous families are dysfunctional or desperate for attention. Through intentional parenting by Sarah Rafferty and Santtu Seppälä, she has been given the greatest gift of all: a normal childhood.
She represents a “quiet life” in a “loud world.” As fans, we might be curious about her, but the best thing we can do is respect the boundaries her family has set. If she chooses to step into the light one day, great. If not, that is great too. For now, Oona Gray Seppala is simply a teenager figuring out who she is, with a loving sister, a supportive dad, and a mom who used to be the best secretary on television. That is a pretty good hand to be dealt.
