Who Is Arabella Sezen Oz?
Arabella Sezen Oz is one of the four children of Dr. Mehmet Oz and Lisa Oz. She works as an actress and writer.
Her middle name, Sezen, reflects her father’s Turkish heritage. Dr. Oz is the son of Turkish immigrants and has kept close ties to Turkey all his life.
Unlike her father and her sister Daphne, Arabella did not build a career in daytime TV. She chose acting and storytelling instead.
She keeps much of her personal life private. Most of what is known about her comes from her film work and her famous family.
Arabella Sezen Oz’s Famous Father
Arabella’s father, Mehmet Cengiz Oz, was born on June 11, 1960, in Cleveland, Ohio. He grew up in Wilmington, Delaware.
He graduated from Harvard University in 1982 and earned both an MD and an MBA from the University of Pennsylvania in 1986. He then became a heart surgeon in New York and later a professor at Columbia University.
He became famous through more than 60 appearances on The Oprah Winfrey Show. In September 2009, he launched The Dr. Oz Show, which ran until January 2022.
In 2022, he ran for the U.S. Senate in Pennsylvania and lost to John Fetterman. Since April 8, 2025, he has served as head of the Centers for Medicare and Medicaid Services.
Arabella Sezen Oz’s Mother, Lisa Oz
Arabella’s mother is Lisa Oz, born Lisa Lemole. She is an author and television personality.
Lisa met Mehmet in Philadelphia through their fathers while he was studying at the University of Pennsylvania. Dr. Oz has said he proposed on a city street corner, using a tab from a soda can as a makeshift ring.
They married in 1985. Lisa later produced her husband’s first TV series, Second Opinion with Dr. Oz, in 2003.
Together, they founded HealthCorps, a nonprofit focused on health education and peer mentoring. Arabella grew up in a home where health, media, and storytelling were part of daily life.
Arabella Sezen Oz’s Siblings
Arabella is one of four children. Her siblings are Daphne, Zoe, and Oliver.
Her older sister, Daphne Oz, is the most famous of the four. She is an author and TV host known for cooking and lifestyle shows. Daphne is married to John Jovanovic, and they have children together.
Her sister Zoe and her brother Oliver have kept lower public profiles.
The Oz family often appears together at major family moments. When Dr. Oz was sworn in at the White House in April 2025, his children’s families were part of the celebration.
Growing Up in a Media Family
Arabella grew up as her father’s fame was rising. By her teenage years, Dr. Oz was a regular face on Oprah’s show.
The family lived for decades in Cliffside Park, New Jersey, just across the river from New York City. That put Arabella close to the city’s theaters and arts scene.
Watching both parents work in TV likely gave her an early look at life in front of a camera. Yet she chose a different kind of performance: acting and creative writing.
That choice set her apart. Instead of following her father into medicine or her sister into lifestyle TV, she followed her own interest in drama.
Arabella Sezen Oz’s Education at Columbia
Arabella studied acting at Columbia University. She is a graduate of Columbia’s drama program, according to a 2015 report from TheWrap.
Columbia is the same university where her father once worked as a professor of surgery. For Arabella, though, the campus became a place to train as an actress.
A formal drama education is a serious step. It shows she wanted real skills, not just a famous name.
Her training soon led to her first major film role.
Arabella Sezen Oz’s Film Debut With Sam Heughan
In January 2015, TheWrap reported that Arabella would star in When the Starlight Ends. It would be her feature film debut.
Her co-star was Sam Heughan, the Scottish actor famous as Jamie Fraser on Outlander. Landing a lead role opposite a rising TV star was a big moment for a newcomer.
The film was written and directed by Adam Sigal, who was also making his first feature. Production began in Los Angeles in February 2015.
Arabella played Cassandra. The story follows a struggling writer who loses the love of his life and tries to rewrite his past through a series of dreamlike scenes.
Winning Best Actress in Venice
When the Starlight Ends premiered at the Other Venice Film Festival in October 2016.
The film did well there. Arabella won the award for Best Feature Film Actress. Sam Heughan won Best Feature Film Actor, and Adam Sigal won for his directing.
For a first feature, that was a strong start. It gave Arabella an award in her very first lead role.
The film was later released on DVD and digital platforms, where fans of Sam Heughan and indie cinema could find it.
Arabella Sezen Oz’s Other Acting Work
Arabella has continued acting since her debut. Her IMDb profile describes her as both an actress and a writer.
She is listed in Our House (2016) and in Jigsaw (2017), a film in the long-running Saw horror series.
Her profile also lists the TV comedy Nightcap from 2016, and an upcoming project called Mallory’s Ghost (2026).
These roles show a working actress building a career step by step, across comedy, drama, and horror.
Arabella Sezen Oz as a Writer
Writing is the other side of Arabella’s creative life. Her IMDb profile lists her as a writer as well as an actress.
Many actors today also write. It gives them more control over their stories and the kinds of roles they play.
Specific details about her writing projects are not widely published. Still, it fits a family that values words. Her mother is an author, and her father has written many bestselling books.
For Arabella, writing may be a way to tell stories in her own voice.
Why People Mix Up Facts About Arabella Sezen Oz
If you search for Arabella online, you may find some strange claims. Some websites call her a heart surgeon, a TV co-host, or the author of health books.
Those claims are not true. They mix her up with her father or her sister Daphne.
Other sites disagree about whether she is the second or youngest child, or give different birth years.
The trusted record is clear on the basics. She is Dr. Oz’s daughter, a Columbia drama graduate, and an actress who won an award for her first lead film role.
Why Arabella Sezen Oz Keeps a Lower Profile
A common question is simple. Why is Arabella less visible than the rest of her family?
Her father has been one of the most famous doctors in America and is now a public official. Her sister Daphne has spent years on national TV.
Arabella has chosen a quieter path. She works in independent film and does not live her life on daytime TV.
That choice gives her room to grow as an artist on her own terms, without being defined only as “Dr. Oz’s daughter.”
Arabella Sezen Oz’s Life Today
As of 2026, Arabella is 35 years old, based on her IMDb birth date.

No trusted source confirms her relationship status or where she lives today. She keeps those details private.
What is clear is that she has carved out her own creative space inside one of America’s best-known families.
Final Thoughts
Arabella Sezen Oz grew up surrounded by cameras, yet she chose the stage and screen in her own way. Her path runs through drama school, small films, and quiet hard work rather than headlines.
Winning an award for her very first lead role was a strong start. Still, her story is less about prizes and more about choosing a passion that is truly her own.
Being part of a famous family can open doors, but walking through them still takes courage. Arabella’s journey reminds us that the most meaningful paths are often the ones we pick for ourselves.
