Alyson Kierans works as an orthodontic therapist in the UK and is the mother of actor Barry Keoghan’s son, Brando. She and Keoghan met in London in early 2021, welcomed Brando in August 2022, and split about a year later. Beyond the relationship, she holds a regulated dental qualification and has built her own career — one that most coverage of her barely mentions.

Her Career as an Orthodontic Therapist
Dental industry records tell a clearer story about Kierans than most entertainment coverage does. Her LinkedIn profile and a staff bio from a UK dental clinic both list her as a qualified orthodontic therapist, and a UK Companies House filing names her as a self-employed director of a dental-related company. She trained at the Royal College of Surgeons Edinburgh, earning a Diploma in Orthodontic Therapy.
That title matters more than it might seem. An orthodontic therapist is a distinct, regulated role — someone who carries out specific parts of an orthodontic treatment plan under a dentist’s or orthodontist’s direction, rather than an orthodontist themselves. Several entertainment outlets have loosely called her an “orthodontist,” but her own professional records use the more precise title.
Is Her Name Alyson Kierans or Alyson Sandro?
Most reliable sources — including her professional records and major outlets like Today.com, Hello!, and E! Online — use the name Alyson Kierans. A smaller number of sites, including some celebrity-news republishes, have referred to her as “Alyson Sandro” or “Alyson Sandro Kierans” instead. No dental, business, or professional record backs up “Sandro” as part of her actual name, so treat “Kierans” as the well-supported version and “Sandro” as an unconfirmed variant that’s spread through less careful reporting.
How Alyson Kierans Met Barry Keoghan
The pair met at a bar in London in February 2021. Their relationship went public later that year, when they made their red-carpet debut together at the UK premiere of Eternals in October 2021, as Today‘s profile of Keoghan’s family life recounts. From there, the relationship continued for roughly two more years. Keoghan, an Irish actor best known for films like Saltburn and The Banshees of Inisherin, has spoken about the relationship and its end in several interviews since.
Their Son, Brando
Kierans and Keoghan welcomed their son, Brando, in August 2022, while Keoghan was filming Saltburn. Keoghan has said he got a single day off from the production to be with his newborn son before returning to night shoots. Since then, he’s spoken publicly and warmly about Kierans as a parent, telling GQ in 2024 that “she’s done a great job, and she’s an incredible mother.”
Why They Split, and Co-Parenting Since
Kierans and Keoghan split around July 2023, after roughly two years together, Hello! Magazine reported. Neither has detailed the reasons publicly. Since the split, Keoghan has continued speaking about Brando in interviews — describing an unconventional but meaningful father-son relationship — while Kierans has largely stayed out of the press herself, occasionally sharing photos of Brando on her own social media.
