Who Is Arabella Sezen Oz?
Arabella is one of the four children of Mehmet and Lisa Oz. Lisa Oz’s Wikipedia page lists her as filmmaker Arabella Oz.
HELLO! and The List describe her as the couple’s second daughter. Both report that she worked as an actress before becoming a therapist.
She has kept a lower profile than her older sister, but she has shared parts of her journey on social media.
Arabella’s Father: Dr. Mehmet Oz
Mehmet Oz was born on June 11, 1960, in Cleveland, Ohio, to Turkish immigrant parents, Mustafa and Suna Öz. He grew up in Wilmington, Delaware.
He earned a biology degree from Harvard in 1982, then an M.D. from the University of Pennsylvania and an MBA from Wharton. He became a heart surgeon and a professor at Columbia University’s medical school.
His TV fame began with more than 60 appearances on The Oprah Winfrey Show, starting in 2004. The Dr. Oz Show ran from 2009 to 2022.
Dr. Oz’s Political Turn
In 2022, Dr. Oz ran as a Republican for the U.S. Senate in Pennsylvania. He lost to John Fetterman by about 4.9 points, according to Wikipedia.
In 2025, the Senate confirmed him as Administrator of the Centers for Medicare & Medicaid Services. He took office on April 8, 2025.
That move put the whole Oz family back in the national spotlight, including Arabella.
Arabella’s Mother: Lisa Oz
Lisa Oz was born Lisa Jane Lemole on July 20, 1963, in Philadelphia. She met Mehmet through their fathers while he was at Penn, and they married in 1985.
Lisa is an author and radio and TV personality. She co-wrote the bestselling You: The Owner’s Manual series with her husband and has hosted The Lisa Oz Show.
She’s also a Reiki master who has spoken widely about energy and health, according to Wikipedia.
Arabella’s Siblings
Arabella grew up as the second of four children.
Her older sister, Daphne Oz, was born in 1986. She became a TV host, best known for ABC’s The Chew, and has four children with her husband, John Jovanovic.
Her younger sister, Zoe, is a Harvard graduate who works as chief marketing officer at Bilt Rewards, HELLO! reports. Her younger brother, Oliver, is the only son and is pursuing a career in medicine.
Studying Film at Columbia
The List and HELLO! report that Arabella studied filmmaking at Columbia University, the same school where her father taught.
She first planned to work behind the camera. The List reports that she took an acting class to better communicate with actors as a director.
To her surprise, she loved performing. That class changed her direction.
Arabella’s First Feature Film
Arabella’s first feature was When the Starlight Ends (2016), a drama co-starring Sam Heughan of Outlander.
She told The Hollywood Reporter, as quoted by The List, that the shooting days were long, but she loved every moment.
For a young actress, working alongside a rising international star was a strong start.
Jigsaw and Billionaire Boys Club
Arabella went on to appear in Jigsaw (2017), part of the long-running Saw horror franchise.
In 2018, she appeared in Billionaire Boys Club, a crime drama based on a real 1980s scandal. The film starred Ansel Elgort and Taron Egerton.
These roles showed her range, from horror to a true-crime-style drama.
A Proud Father in the Audience
Dr. Oz supported his daughter’s acting. In 2017, he attended a film festival in Boca Raton, Florida, where one of her films was showing, The List reports.
He told the South Florida Sun Sentinel that she was the kindest of his kids and that she taps into deeper emotions.
That emotional depth would later shape the next chapter of her life.
From Acting to Therapy
Arabella eventually stepped away from the entertainment industry. HELLO! and The List report that she became a therapist.
In a 2020 Facebook tribute for her 30th birthday, Dr. Oz wrote that she was working as a therapist and guiding people through turbulent times, according to The List.
She now speaks openly on social media about mental health and healing from trauma.
Balancing Privacy and Openness
Being a therapist from a famous family is a tricky balance. In a 2023 Instagram post, quoted by The List and HELLO!, Arabella wrote that being a therapist with a public family made her always aware of how open she could be.
She also said she felt a growing desire for more self-expression.
That honesty about the tension is part of what makes her story stand out.
Marriage to Nicholas Canellakis
In 2024, Arabella married Nicholas Canellakis, an American cellist. Dr. Oz shared wedding photos on Instagram, writing that every father dreams of walking his daughter down the aisle to marry Prince Charming, The List reported.
HELLO! also reported his post saying that the fairy tale had come true for the family once again.
It was another family wedding for the Oz clan, which had celebrated Oliver’s marriage in 2023.
Who Is Nicholas Canellakis?
Nicholas Canellakis was born in 1984 in New York City, according to Wikipedia. He trained at the Curtis Institute of Music and the New England Conservatory.
He made his Carnegie Hall concerto debut in 2015 with the American Symphony Orchestra. He’s an artist with the Chamber Music Society of Lincoln Center and the artistic director of Chamber Music Sedona.

Clearing Up the Confusion About Arabella Sezen Oz
Many websites write about Arabella with details that aren’t confirmed. Here is what to keep in mind.
Her middle name. “Sezen” is widely used online but isn’t in a trusted source we found.
Her birthday. Sites list exact dates. Her father’s post confirms only that she turned 30 in 2020.
Her therapy practice. Sites name specialties or offices without sources.
Children. No trusted source reports that Arabella has children.
Net worth. Any figure online is a guess.
Why Arabella Oz Keeps a Lower Profile
Arabella’s sister Daphne built a public TV career. Arabella’s work as a therapist calls for something different: trust and discretion.
She has said openly that she has to think carefully about how much to share. Her clients’ trust depends on it.
That’s why she shares ideas about healing more than details about her personal life.

Final Thoughts
Some people find their calling right away. Others find it by following one passion until it leads them somewhere unexpected. Arabella Oz went to film school to work behind the camera, discovered she loved acting, and then discovered she loved helping people even more.
There’s a thread running through all of it. A good actor and a good therapist both need to understand what people feel beneath the surface. Her father noticed it years ago, when he said she taps into deeper emotions.
Her story raises a gentle question. What if the twists in our career aren’t detours at all, but the slow discovery of what we were always meant to do?
