Her Family Background
Oona’s parents are Sarah Rafferty and Santtu Seppälä. They married in 2001, several years before Oona was born. The family has spent time in both the United States and Canada. This was mainly because Suits was filmed in Toronto while the family also had a home life in Los Angeles. Sarah has spoken with care about raising her children while working on a long-running show. She often tried to keep her work life and family life close. At the same time, she did not turn her daughters into public figures.
Sarah Rafferty, Oona’s Mother
Sarah Rafferty is an American actress. She became widely known for playing Donna Paulsen in all nine seasons of Suits. Donna was smart, funny, and confident. The role brought Sarah fans from many countries. The show later gained a new audience through streaming, especially after it became popular on Netflix in 2023. Sarah has also appeared in shows such as Chicago Med and My Life with the Walter Boys. She later took part in a Suits rewatch podcast with her former co-star Patrick J. Adams. Her ongoing work has helped keep public interest in her family strong.
Santtu Seppälä, Oona’s Father
Oona’s father is Santtu Seppälä. His longer name has been reported as Aleksanteri Olli-Pekka Seppälä. He usually uses the name Santtu. He has worked in finance and has kept a much lower public profile than his wife. Reports say Sarah and Santtu met while they were connected to Yale. They married in Greenwich, Connecticut, in June 2001. Santtu is not an actor, and he does not appear often in entertainment news. No verified public social media page for him is widely known. His private life should not be filled with guesses.
Oona’s Younger Sister, Iris
Oona has one younger sister named Iris Friday Seppälä. Iris was born on January 27, 2012. This makes her a little more than four years younger than Oona. Sarah Rafferty has shared small stories about both girls in past interviews. She once said they liked to sing, dance, joke, and make the family laugh. These comments described normal childhood fun. They did not prove that either daughter planned to become a singer, dancer, or actress. It is important not to turn a parent’s sweet family story into a claim about a professional career.
Growing Up Between Los Angeles and Toronto
Oona’s early years were shaped by her mother’s work on Suits. The show filmed in Toronto, Canada, while the family also spent time in Los Angeles. Sarah spoke in past interviews about the challenge of moving between the two cities. She said she once worried about how the travel and school changes might affect Oona. Over time, she felt that the experience helped her daughter grow more confident. Oona learned how to adjust to different places and routines. Still, exact details about her schools have not been widely shared.
Life Around the Suits Set
Oona and Iris sometimes visited the Suits set when they were young. Sarah said the girls enjoyed places such as the hair and makeup area, the clothing rooms, and the food station. They also spent time near the cast and crew. The set was not a strange celebrity world to them. It was simply where their mother worked. Sarah has said the children learned common set words such as “action” and “cut.” She also kept photos of them trying on special clothes. There is no public record showing that Oona acted in the series or received an official screen credit.
Education and Personal Interests
Only a small amount is publicly known about Oona’s education. Her mother said she attended school in Los Angeles and Toronto during the years when Suits was being filmed. Oona reached college age in 2025 and 2026. However, no college, course, major, grade, or future study plan has been publicly confirmed. Websites that claim to know her school or career plan may be guessing. Sarah Rafferty studied at Hamilton College and later trained at the Yale School of Drama. That does not mean Oona chose the same path. Her own plans remain private.
Sarah has said that Oona and Iris enjoyed singing and dancing when they were children. This is common for many young children. It does not mean Oona has started a public music, dance, or acting career. No verified interview from Oona explains her hobbies today. She may have many interests that the public does not know about. Since she keeps a private life, readers should avoid making claims about her skills, goals, or personality without a direct source.
Does Oona Gray Seppala Have a Career?
There is no publicly confirmed career for Oona Gray Seppala as of 2026. Some biography websites call her an actress, singer, dancer, or rising star. These labels do not appear to be supported by known screen credits, music releases, talent pages, or interviews. No major professional listing has been widely linked to her name. It is possible that she is studying, working, or planning a future career in private. However, it would be wrong to name a career without proof.
The following claims are not publicly confirmed:
- That Oona is a professional actress
- That she has released music
- That she has a dance career
- That she has signed with a talent agency
- That she has a public business
- That she has earned a large personal net worth
Some websites also publish net worth numbers for Oona. These figures should not be trusted. She has no widely known public income, company, acting role, or music deal. Her personal finances have not been shared. A private person’s net worth cannot be known just because one parent is famous.
Social Media and Public Life
Oona does not appear to have a verified public account on Instagram, TikTok, or X. Accounts using her name should be treated with care unless they are confirmed by Oona or her family. Most known pictures of her were shared by Sarah Rafferty. These posts often marked birthdays or family moments. Sarah has not built her public image around her children. She usually appears at work events alone or with her husband. Oona has also not given a known interview in a major news or entertainment outlet.
This limited online record appears to be a family choice. Sarah has shared love for her daughters while keeping many parts of their lives away from public view. She has not announced private school details, close friendships, dating information, or personal plans. Oona became a legal adult in October 2025, but that does not make every part of her life public. Being related to an actress does not remove a person’s right to privacy.
Why Are People Interested in Oona?
Interest in Oona grew as Suits became popular again through streaming. The show first ran from 2011 to 2019. In 2023, it found many new viewers on Netflix. Fans who discovered Donna Paulsen often searched for Sarah Rafferty. Some then looked for information about her husband and children. Oona’s 18th birthday in October 2025 also led to more age searches. This is why the phrase oona gray seppala age appears on many celebrity information sites.
The problem is that there are only a few confirmed facts. Some sites try to fill the empty space with guesses. They may repeat the same claims without naming a source. They may also use old ages, fake social media pages, or made-up career details. A good article should separate facts from guesses. Birth records reported by trusted outlets, direct interviews with Sarah, and dated family posts are more useful than pages that do not explain where their information came from.
Helpful Ways to Check Claims
Before trusting an article about Oona, look for clear proof. A reliable page should show where each fact came from. It should not treat a guess as a fact.
Watch for these warning signs:
- A net worth number with no business or income source
- A career claim with no role, song, agency, or official page
- A school name that the family has never shared
- A social account with no family confirmation
- Long personality claims with no interview
- An age that does not match her birth date
Better information often comes from direct interviews with Sarah Rafferty, trusted news reports, or Sarah’s verified posts. Even then, readers should respect the limit of what the family has chosen to share.
Final Thoughts
