Alyson Sandro Biography: Age, Career, Family, Barry Keoghan & Net Worth

Alyson Sandro is a Scottish-born dental professional who became widely known through her relationship with Irish actor Barry Keoghan. While entertainment coverage has largely described her as Keoghan’s former partner and the mother of his son, her own professional identity is considerably more substantial than that label suggests. Professional and corporate records identify her as Alyson Kierans, an orthodontic therapist with a background in dental care and a directorship in an orthodontic company.

Sandro and Keoghan began dating in 2021 after meeting at a London pub. They later welcomed their son, Brando, in August 2022. The couple appeared together publicly at events including the Eternals premiere and the 2023 Academy Awards before their relationship ended in 2023.

Much of what is available online about Alyson focuses on her connection to Keoghan. A closer look at professional records, however, reveals a different side of her story: a career in dentistry and orthodontic therapy, specialist training, professional registration, and involvement in an orthodontic business. That distinction is important when separating documented biography from celebrity speculation.

Who Is Alyson Sandro?

Alyson Sandro is best known publicly as Barry Keoghan’s former partner and the mother of his son, Brando. She is also a dental professional whose career includes orthodontic therapy.

British GQ introduced her in 2022 as Keoghan’s Scottish orthodontist girlfriend. The same interview provides unusually valuable first-person information because it records both Keoghan and Sandro discussing how they met and their family life at the time.

That professional identity is sometimes obscured by entertainment coverage. Many articles describe Sandro primarily through Keoghan, but professional sources provide evidence of her own career. She qualified as an orthodontic therapist in 2017 after studying at the Royal College of Surgeons Edinburgh and has worked in dentistry for more than a decade, according to her professional profile.

She is also connected to Alyson Orthodontics Ltd, a UK company incorporated in October 2019, where Companies House lists Alyson Kierans as a director.

So, although the name Alyson Sandro became familiar because of a celebrity relationship, the available evidence supports a broader description: she is a Scottish/British dental professional with a career in orthodontic therapy and a documented business role.

Quick Facts About Alyson Sandro

The April 1987 birth information comes from Companies House, which lists Alyson Kierans as a British national and director of Alyson Orthodontics Ltd. Her professional profile identifies her as an orthodontic therapist and gives her GDC number as 190511.

Alyson Sandro’s Real Name: Sandro or Kierans?

One of the more confusing aspects of online coverage is Alyson’s name.

Entertainment publications generally use Alyson Sandro, while professional and corporate records identify her as Alyson Kierans. British GQ itself referred to her as Alyson Sandro, while The Standard has used both Alyson Kierans and Miss Sandro when discussing the same person.

Some secondary biography websites combine the names into Alyson Sandro Kierans, but the research available here does not establish that this is her legally registered full name.

For that reason, it is more accurate to distinguish between the names rather than declare one unsupported “real name”:

• Alyson Sandro — the name widely used in entertainment and celebrity coverage.
• Alyson Kierans — the name appearing in professional and corporate records.
• Alyson Sandro Kierans — a combined form used by some secondary websites, but not independently established as her legal name.

This distinction matters because biography websites often repeat one another. In Alyson’s case, the official corporate record is stronger evidence than an unsourced celebrity biography page.

Alyson Sandro’s Age and Birthday

Companies House lists Alyson Kierans as being born in April 1987. On that evidence, she is 39 years old as of August 2026.

Some entertainment and biography websites have published a specific April birthday, but the exact day is not as strongly established as the month and year in the corporate record.

There are also conflicting dates on low-quality celebrity sites. Those should not be treated as reliable simply because they are repeated online.

How old is Alyson Sandro?

Alyson Sandro is 39 years old as of August 2026 if the April 1987 Companies House record is used.

The safest factual description is therefore born in April 1987, rather than presenting an exact day as certain without a stronger primary source.

Where Is Alyson Sandro From?

Alyson Sandro is widely described as Scottish and as being from Scotland.

British GQ described her as a Scottish orthodontist, while entertainment coverage has repeatedly identified her as a Scotland native.

Her Scottish background also became relevant during her relationship with Barry Keoghan. In the 2022 GQ interview, the couple discussed plans to move north to Scotland so they could be closer to Alyson’s family.

The available public record does not establish a precise birthplace in a sufficiently authoritative source, so it is better to say that she is Scottish and from Scotland rather than inventing a specific hometown.

Early Life and Family Background

Public information about Alyson’s childhood is surprisingly limited.

Unlike Barry Keoghan, whose childhood and family history have been extensively discussed in interviews, Alyson has largely remained a private individual. Most publicly available information about her early life comes from entertainment articles rather than detailed autobiographical interviews.

What can be established is her Scottish background and her later career in dentistry.

Some secondary reports have stated that her father had roots in County Cavan, Ireland, but the available research does not include sufficiently strong primary evidence to establish his identity or complete family history.

What is known about Alyson Sandro’s family?

The strongest publicly documented family connection is her son, Brando, whom she shares with Barry Keoghan.

Beyond that, reliable public information about her immediate family is limited. That lack of information should not be filled with assumptions.

Education and Professional Training

Alyson’s professional education is one of the most useful areas for understanding her independently of celebrity coverage.

Her professional profile identifies training at the Royal College of Surgeons Edinburgh, where she qualified as an orthodontic therapist in 2017.

Her professional information also identifies dental-related training, including qualifications in dental radiography and child oral healthcare.

The available evidence therefore supports a career path that developed within the dental profession rather than an entertainment career.

Alyson Sandro’s education at a glance

The exact details of every earlier school or college attended by Alyson are not firmly established in authoritative public records, so they should not be presented as fact.

Alyson Sandro Career as an Orthodontic Therapist

Alyson’s career is perhaps the most important part of her biography that receives too little attention in celebrity coverage.

She has worked in dentistry for more than ten years, according to her professional profile, and later specialized as an orthodontic therapist.

What does an orthodontic therapist do?

An orthodontic therapist is a dental professional who works as part of an orthodontic team. The role can involve supporting orthodontic treatment under the direction and prescription of an appropriate dental professional.

This is different from simply calling someone a dentist or an orthodontist.

That distinction is important because some entertainment publications have loosely described Alyson as a dentist. Stronger professional evidence identifies her specifically as an orthodontic therapist, while other reporting describes her as a dental nurse and orthodontic therapist.

Her professional experience

Her professional profile states that she has experience with orthodontic treatment and has been involved in more complex cases, including patients with hypodontia and cases involving orthognathic surgery.

That information gives a much clearer picture of her professional development than simply describing her as “Barry Keoghan’s ex.”

Why her orthodontic qualification matters

Qualifying as an orthodontic therapist in 2017 represents a major step in Alyson’s career.

It indicates a move from broader dental work toward a specialist orthodontic role. Combined with her later business directorship, the public record shows a progression from dental training to specialized professional practice and business involvement.

Alyson Orthodontics Ltd

Another important part of Alyson’s professional story is her connection with Alyson Orthodontics Ltd.

Companies House records show:

• Company: Alyson Orthodontics Ltd
• Company number: 12254352
• Incorporated: October 10, 2019
• Status: Active
• Director: Alyson Kierans
• Nationality recorded: British
• Business classifications: specialist medical practice activities and dental practice activities.

This is valuable information because many biography pages omit the corporate record entirely.

What does her director role mean?

It establishes a formal business connection between Alyson Kierans and the company.

It does not, however, prove her personal income, the company’s revenue, profitability, or her personal net worth.

Being a company director should therefore be described as a documented leadership/business role, not automatically as evidence of substantial wealth.

Career Timeline – Alyson Sandro

Alyson Sandro and Barry Keoghan

Alyson became internationally recognizable largely because of her relationship with Barry Keoghan, the Irish actor known for films including The Banshees of Inisherin, Eternals and Saltburn.

The couple’s relationship began in February 2021, after they met in a pub in London. Keoghan later described the encounter in British GQ. According to the interview, Alyson was not particularly impressed when he told her he was an actor. She even jokingly asked whether he played Spider-Man after he said he was in a superhero movie.

Keoghan eventually showed her photographs from his work on Eternals to demonstrate that he was telling the truth.

That detail is one of the few parts of their relationship story that comes directly from a first-person interview rather than later celebrity reporting.

When did Alyson Sandro and Barry Keoghan start dating?

They began dating in February 2021, after meeting at a London pub.

Their relationship became more visible later that year.

They eventually appeared together at the UK premiere of Eternals, giving the public a clearer indication that they were a couple.

The couple increasingly appeared together publicly.

March 2023 — Academy Awards

2023 — Separation

Reports of their separation emerged in 2023, with the relationship generally understood to have ended around the summer of that year.

January 2024 — Keoghan comments publicly

In a GQ interview, Keoghan did not provide a detailed explanation for the breakup but described Alyson as having “done a great job” and being an “incredible mother.”

Who Is Alyson Sandro’s Son?

Alyson Sandro and Barry Keoghan share one son, Brando.

Brando was born in August 2022, during the period when Keoghan was filming Saltburn. Keoghan told GQ that the production gave him time away from filming for the birth.

The child’s name, Brando, is widely understood to be connected to actor Marlon Brando, one of Keoghan’s acting influences.

The birth represented an important period in Alyson’s public story because she became a mother while maintaining a relatively private life outside entertainment.

Alyson Sandro as a mother

Public comments from Keoghan have been positive regarding Alyson’s role as Brando’s mother. In his GQ interview, he specifically praised her as an “incredible mother.”

That is one of the strongest direct public comments about Alyson from her former partner.

Why Did Alyson Sandro and Barry Keoghan Break Up?

This is one of the most searched questions about Alyson, but it is also one of the areas where careful wording is essential.

The breakup itself is well established. Reports emerged in 2023, and later coverage confirmed that Alyson and Keoghan were no longer together.

The exact reason, however, has never been authoritatively established by both parties.

Some tabloid reports attributed tension to disagreements over partying and late nights. The Standard repeated those reports while clearly attributing them to The Sun.

What is confirmed?

• They began dating in 2021.
• They had a child in 2022.
• Their relationship ended in 2023.
• Keoghan later praised Alyson as a mother.
• The precise cause of the breakup was not publicly established in a definitive statement from both parties.

What should not be treated as fact?

Claims that:

• Barry definitely cheated on Alyson
• Alyson publicly accused him of cheating
• partying was conclusively responsible for the breakup
• either person gave a detailed public account of every reason for the separation

are not supported strongly enough to be presented as established facts.

Alyson Sandro’s Life After the Breakup

After the relationship ended, Alyson remained a relatively private figure.

Her continued public relevance has largely come from her connection to Brando and from media interest in Keoghan’s subsequent personal life.

In 2024, media attention focused on reports that Alyson had liked social-media comments discussing single motherhood and raising children alone. The South China Morning Post reported the activity and the interpretation that some observers placed on it.

However, liking a social-media comment is not the same as making a formal public statement.

For that reason, it is more accurate to say that her social-media activity generated speculation than to claim that she publicly accused Keoghan of failing as a parent.

Alyson Sandro’s Social Media

The Instagram account most commonly associated with Alyson is @alyson_kierans.

Entertainment coverage has connected the account to personal photographs and posts involving her family life. She has reportedly shared milestones involving her son, including birthday-related content.

Major Achievements of Alyson Sandro

Alyson does not have a public career defined by entertainment awards, acting credits or celebrity honors.

Her documented achievements are primarily professional.

Orthodontic therapy qualification

One of her clearest career milestones is qualifying as an orthodontic therapist in 2017 through the Royal College of Surgeons Edinburgh.

Experience in orthodontic care

Her professional profile states that she has experience with orthodontic treatment, including more complex cases.

Professional registration

Her professional profile lists GDC number 190511, providing a concrete professional identifier.

Business leadership

Companies House lists Alyson Kierans as a director of Alyson Orthodontics Ltd, incorporated in 2019.

Together, these achievements show a career progression from dental work into specialist orthodontic therapy and business leadership.

Alyson Sandro’s Business Ventures

The principal documented business connection is Alyson Orthodontics Ltd.

There is no reliable evidence in the available research of a portfolio of celebrity investments, fashion brands, product lines or entertainment businesses.

This is an important distinction because some celebrity biographies create an impression of extensive entrepreneurship by listing companies without explaining what the person actually did.

In Alyson’s case, the strongest corporate evidence establishes her as a director of a dental/orthodontic company.

There is not enough evidence to claim that she operates a large national business or has accumulated significant wealth from it.

Net Worth of Alyson Sandro

There is no authoritative public figure establishing Alyson Sandro’s personal net worth.

Some secondary celebrity-biography websites have estimated her wealth at around $550,000, but that figure is not supported by a public financial disclosure or an independently documented calculation.

Therefore, $550,000 should be regarded as an online estimate rather than a verified net-worth figure.

Her professional background and business role provide plausible sources of income, but they do not reveal:

• her salary
• personal investments
• savings
• property ownership
• business profits
• taxes
• debts
• total assets

Companies House records the existence and corporate status of Alyson Orthodontics Ltd, but corporate registration alone cannot establish a director’s personal wealth.

What is Alyson Sandro’s net worth?

Alyson Sandro’s exact net worth is not publicly verified. Some secondary websites estimate it at approximately $550,000, but there is insufficient authoritative evidence to treat that number as fact.

Philanthropy and Charity Work

There is currently no reliably documented personal foundation, charity or major philanthropic organization associated with Alyson Sandro in the available research.

This does not mean she has never supported a charitable cause. It means there is not enough reliable public documentation to identify specific philanthropic work as part of her biography.

A responsible biography should not turn an absence of public records into either a positive or negative conclusion.

Challenges and Public Controversies of Alyson Sandro

Alyson’s public challenges have largely resulted from the intense attention surrounding her relationship with a high-profile actor.

Celebrity scrutiny

Her private life became public through her relationship with Barry Keoghan. As a result, details about her family, social-media activity and relationship status have been discussed extensively by entertainment media even though she has not built a career in the public spotlight.

Breakup speculation

The 2023 breakup generated reports about the reasons behind the separation. Some reports attributed relationship problems to disagreements over partying, but those explanations remain reported claims rather than established facts.

Social-media speculation

Her reported likes on posts concerning single motherhood also attracted attention in 2024. The significance of those likes was interpreted by observers, but the likes themselves do not establish a detailed public statement about her relationship with Keoghan.

Important distinction

There is no verified evidence in the available research of a major legal controversy, criminal case or formal professional disciplinary matter involving Alyson.

Alyson Sandro’s Public Image

Alyson’s public image is unusual because she did not become famous through a conventional public career.

Her recognition came largely from her relationship with Barry Keoghan, but the available evidence shows that she had already developed a professional career in dentistry and orthodontic therapy.

That creates two very different versions of Alyson online.

The first is the celebrity-media version:

• Barry Keoghan’s former partner
• mother of his son
• Oscars date
• subject of relationship stories

The second is the professional version:

• dental professional
• orthodontic therapist
• specialist trainee
• GDC-identified practitioner
• company director

The second identity deserves greater attention because it is supported by professional and corporate records rather than celebrity speculation.

Influence and Legacy of Alyson Sandro

It would be premature to describe Alyson Sandro as a major public figure with an established cultural legacy.

Her professional career is documented, but there is not enough public evidence to measure a large-scale impact on the orthodontic industry.

Her public significance currently comes from three areas:

1. Her professional career in dental and orthodontic care
2. Her relationship with Barry Keoghan
3. Her role as the mother of Brando Keoghan

The most meaningful long-term aspect of her biography may ultimately be her professional identity rather than the celebrity relationship that introduced her to a global audience.

Her story also illustrates a broader point about modern celebrity culture: a person can become highly searchable because of a famous partner even when their own professional life has little connection to entertainment.

Conclusion

Alyson Sandro’s public identity is often reduced to one description: Barry Keoghan’s former girlfriend. That description explains why she became widely known, but it does not tell the whole story.

The stronger public record shows a woman with an established professional career in dental care. Known professionally as Alyson Kierans, she trained as an orthodontic therapist at the Royal College of Surgeons Edinburgh and qualified in 2017. Her professional profile identifies experience in orthodontic treatment and gives her GDC number as 190511. She is also listed as a director of Alyson Orthodontics Ltd, a company incorporated in 2019.

Her relationship with Barry Keoghan remains an important part of her public biography. They met in London in February 2021, welcomed their son Brando in August 2022, appeared together publicly at events including the Eternals premiere and the 2023 Academy Awards, and separated in 2023. Keoghan later publicly praised Alyson’s role as Brando’s mother.

At the same time, many details frequently repeated online—particularly exact net worth, precise family information, legal name variations, current relationship status and the definitive reason for the breakup—remain either unverified or incompletely documented.

That distinction is central to understanding Alyson Sandro accurately. She is a private professional whose public profile expanded because of a famous relationship, but the most concrete evidence about her own life points to orthodontic therapy, dental care, professional training and business involvement.
