When people search for Nellie Biles, they often know her first as the woman who raised Simone Biles. But that description only tells part of her story. Nellie Biles became a central figure in Simone’s life after helping provide a stable home during a difficult period of childhood. Later, she and her husband, Ronald Biles, built a gymnastics training center that became closely associated with one of the greatest gymnasts in history.
That naturally raises several questions: Did Nellie Biles adopt Simone? Where is Nellie Biles from? What is her nationality? And what gym does she own?
The answers are more interesting than a typical celebrity-family biography suggests. Nellie is Simone’s maternal grandfather’s wife rather than her biological grandmother, yet she became her adoptive mother. She also has a significant connection to Belize, having been born and raised there before moving to the United States. And her involvement in gymnastics goes beyond simply supporting Simone: she helped create the World Champions Centre in Texas as a dedicated training environment.
Here is what is known about Nellie Biles, her family, adoption story, nationality and career.
Who is Nellie Biles?
Nellie Biles is best known as the adoptive mother of Olympic gymnast Simone Biles and as the wife of Ronald Biles.
Her family story is slightly more complicated than the simple label “Simone Biles’ grandmother.” Ronald Biles is Simone’s biological maternal grandfather. Nellie is Ronald’s second wife, which makes her Simone’s step-grandmother by marriage. After Simone and her younger sister, Adria, entered foster care, however, Nellie and Ronald became their parents in practice and eventually adopted them.
Nellie’s background also extends beyond her famous daughter. She worked as a nurse and later became involved in business and gymnastics. Today, she is associated with the World Champions Centre, the large gymnastics facility in Spring, Texas, that she owns with Ronald.
The facility’s official information identifies Ron and Nellie Biles as its owners.
Did Nellie Biles adopt Simone Biles?
Yes. Nellie Biles and Ronald Biles formally adopted Simone Biles and her younger sister, Adria, when Simone was six.
The adoption followed a difficult period in which Simone and her siblings were placed in foster care because their biological mother, Shanon Biles, was unable to care for them. Simone and Adria eventually went to live with Ronald and Nellie in Texas, while their two older siblings were adopted by another relative.
This distinction matters because Nellie was not Simone’s biological maternal grandmother. She was married to Simone’s maternal grandfather, Ronald, and became her adoptive mother.
For many years, the family did not make this complicated history the centerpiece of Simone’s public identity. Nellie has described the emotional difficulty of suddenly becoming a parent to young children after she and Ronald had already raised two sons.
That transition was not effortless.
Nellie has spoken about needing time to develop the emotional bond that eventually became central to their family. Reporting from the Associated Press and other outlets has described how she and Ronald worked through the adjustment and built a stable family environment.
Why the adoption story is important
It explains something that can easily be missed when looking only at Simone’s gymnastics career.
Simone did not simply have a talented coach or a supportive sports family. She had a family structure that changed dramatically during childhood.
Nellie and Ronald provided:
- A permanent home
- Consistent parental support
- Transportation and logistical help for gymnastics
- Emotional stability
- Long-term encouragement
- Support through Simone’s Olympic career
Simone has repeatedly credited her parents for giving her the foundation she needed to pursue gymnastics at the highest level.
What is Nellie Biles’ nationality?
Nellie Biles has a strong Belizean connection and is generally described as Belizean-American.
Unlike Simone, who was born in Columbus, Ohio, Nellie Cayetano Biles was born in Belize and later moved to the United States as a young woman.
Belizean reporting identifies Nellie Cayetano Biles as the daughter of Silas Cayetano, a prominent Belizean figure, and describes her as having left Belize for the United States to pursue nursing education.
This background also explains why Belize has played such an important role in Simone Biles’ identity.
Simone has Belizean citizenship through Nellie and has repeatedly described Belize as a second home. Belizean media have highlighted the connection for years, particularly after Simone’s success at the 2016 Rio Olympics.
So when people search for Nellie Biles nationality, the clearest way to understand the answer is:
- Nellie was born in Belize.
- Her family roots are Belizean.
- She moved to the United States as a young adult.
- She built her family and professional life in Texas.
- Her Belizean heritage is an important part of the Biles family’s connection to the country.
Some online biographies give conflicting details about her exact birthplace and date of birth. For that reason, it is better to rely on Belizean reporting about her origins rather than repeating every figure found on celebrity-biography websites.
Nellie Biles’ connection to Belize
Nellie’s Belizean background is not merely a biographical footnote.
She has actively maintained a relationship with the country and has taken her children there over the years. In a 2016 interview with 7 News Belize, she explained that she wanted her children to know where she came from and to feel connected to Belize.
That helps explain why Simone has such a personal relationship with Belize.
The connection is also a useful reminder that celebrity family histories can contain several layers. Simone is an American Olympic athlete, but her family heritage through Nellie gives her a direct connection to Belize as well.
What gym does Nellie Biles own?
Nellie Biles is a co-owner of the World Champions Centre (WCC) in Spring, Texas, alongside Ronald Biles.
The facility was established in 2014 and developed into a major training environment for elite gymnastics. Its stated mission goes beyond producing champions; the center also offers gymnastics, tumbling, trampoline, cheer and other programs.
The gym became particularly famous because Simone Biles trained there.
But there is an important detail that is sometimes lost online: Simone Biles does not own the World Champions Centre.
Nellie and Ronald have been identified as the owners, while Simone has been one of the gym’s most prominent athletes. The Houston Chronicle reported that Nellie wanted the facility to develop an identity beyond simply being “Simone Biles’ gym.”
That distinction is important when researching Nellie Biles gym.
Why did Nellie Biles build the gym?
The idea grew out of Simone’s rapidly developing gymnastics career.
After Simone won her first world all-around title in 2013, Nellie began considering a facility where Simone and other athletes could train in a high-quality environment. Her longtime coach, Aimee Boorman, was also facing a change in her coaching situation.
Rather than have Simone constantly adjust to changing facilities, Nellie helped create a new solution.
The result was the World Champions Centre.
The gym officially became a major part of the family’s approach to elite gymnastics, providing Simone and other athletes with a dedicated training base.
What makes World Champions Centre different?
The most interesting aspect of WCC is that it was not created simply as a monument to Simone.
Nellie’s stated ambition has been to develop athletes who can build their own identities and achievements.
The Houston Chronicle reported that the facility’s walls and culture were deliberately not centered entirely on Simone’s accomplishments. The gym has supported other elite and collegiate gymnasts, helping create a broader training ecosystem.
That is one of the less commonly discussed parts of Nellie’s contribution.
She helped turn a family’s solution to one gymnast’s training needs into an institution capable of supporting many athletes.
Nellie Biles’ career before gymnastics
Nellie’s professional background was not originally in sports.
She studied nursing after moving from Belize to Texas and worked as a nurse. She later became involved in business with Ronald, including nursing-home operations, before becoming increasingly involved in gymnastics through Simone’s career and the World Champions Centre.
This background helps explain why her role at WCC has often been different from that of a traditional gymnastics coach.
She is primarily a parent, owner and organizational figure rather than the person teaching Simone technical gymnastics skills.
The coaching side has been handled by professional gymnastics coaches, while Nellie has helped provide the infrastructure and environment around the athletes.
Nellie Biles and Simone Biles: more than an adoption story
One of the easiest mistakes when researching Nellie is to reduce her entire life to Simone’s adoption.
The adoption is certainly a major part of their story, but their relationship continued to evolve for decades.
Nellie became the parent who attended competitions, helped manage the practical demands of elite gymnastics and supported Simone through both victories and difficult periods.
During the Tokyo Olympics in 2021, Simone withdrew from several events after experiencing the “twisties.” Her parents were unable to attend the Games because of pandemic-related restrictions, something Simone later described as particularly difficult because they had normally been present at her competitions.
The episode demonstrated something important about Nellie’s role: her value to Simone was never limited to gymnastics results.
She was part of Simone’s emotional support system long before the athlete became a global superstar.
A less obvious part of Nellie’s story: building beyond Simone
There is a useful lesson in the history of World Champions Centre.
When an athlete becomes extraordinarily successful, it can be tempting for a business built around that athlete to depend entirely on their fame. Nellie appears to have recognized the risk.
The goal became larger than creating a place for Simone to train.
WCC developed programs for younger gymnasts and elite competitors, and it attracted other high-level athletes. By 2023, the Houston Chronicle described it as a major destination for elite gymnastics talent.
This is one of the most significant but least discussed parts of Nellie’s work.
Her contribution is not only that she helped Simone reach the gym every day. She helped create an environment in which other athletes could pursue their own careers.
Where is Nellie Biles now?
Nellie Biles continues to be associated with the World Champions Centre in Spring, Texas.
The center remains a major part of the Biles family’s involvement in gymnastics. Its official organization lists Ron and Nellie as owners and emphasizes a combination of athletic development, safety, teamwork and personal growth.
Nellie has also been involved in charitable and community-oriented work. Friends of the Children identifies her as a co-founder of World Champions Centre and highlights her involvement in youth-focused and foster-care advocacy.
Her story therefore extends beyond being the parent of an Olympic champion.
She has worked in healthcare, raised children, navigated adoption, supported elite sport and helped establish a major gymnastics facility.
Is Nellie Biles Simone Biles’ biological mother?
No. Nellie Biles is Simone Biles’ adoptive mother.
Simone’s biological mother is Shanon Biles. Nellie is the second wife of Simone’s biological maternal grandfather, Ronald Biles. Nellie and Ronald adopted Simone and her sister Adria after the children had spent time in foster care.
This is why some sources describe Nellie as Simone’s grandmother while others call her mother.
Both descriptions reflect different parts of the family relationship, but “adoptive mother” is the most precise description after the adoption.

Why is Nellie Biles important to Simone Biles’ story?

Conclusion
Nellie Biles’ story is much bigger than the label “Simone Biles’ mom.”
She became Simone’s adoptive mother after a difficult childhood and helped provide the stable family environment in which the future Olympic champion could grow. Her own background is rooted in Belize, where she was born before moving to the United States and building a life in Texas.
Her contribution to gymnastics also took a practical form. Alongside Ronald Biles, she helped establish the World Champions Centre in Spring, Texas, transforming the family’s need for a reliable training home into a facility that could serve generations of athletes.
Perhaps the most revealing part of Nellie’s story is that her ambitions for the gym have never been limited to Simone. The long-term goal has been to create a place where young athletes can develop safely, compete at the highest level and eventually become known for their own achievements.
That makes Nellie Biles an important figure in her own right—not because she performed Simone’s routines, but because she helped build the family and environment in which those routines became possible
