Guilherme Augusto Vieira dos Santos comes from a close Brazilian family that has remained an important source of support throughout his long professional football career. Better known simply as Guilherme, the Houston Dynamo FC attacker has played in Brazil, Saudi Arabia, the United Arab Emirates and the United States, with his family accompanying him through many of those changes.
Guilherme is married to Tainá, and the couple have two children: a daughter named Pietra and a son named Guilherme Júnior. The Brazilian forward regularly speaks about how much his wife and children mean to him and has frequently included Pietra and Guilherme Jr. in memorable moments from his football career. Information about Guilherme’s parents and siblings is considerably more private, although he has publicly acknowledged them as important members of his support network.
Who Is Guilherme Augusto’s Wife?
Guilherme Augusto’s wife is Tainá.
Tainá has supported Guilherme through several stages of a career that has required the family to move between different cities and countries.
She became particularly visible publicly during Guilherme’s periods with Fortaleza and Santos, when Brazilian media interviewed the family about the challenges and emotional pressures associated with professional football.
During Guilherme’s 2023 season with Fortaleza, Tainá spoke publicly about the importance of family support while her husband was dealing with criticism and difficult moments on the field.
She explained that she and their children continued believing in Guilherme during the difficult period and relied heavily on faith while supporting him.
That support became especially meaningful when Guilherme eventually recovered his form and became an important player during Fortaleza’s run to the 2023 Copa Sudamericana final.
How Long Have Guilherme and Tainá Been Together?
The exact date when Guilherme and Tainá began their relationship has not been widely documented by reliable public sources.
However, they were already together before the birth of their first child, Pietra, and Tainá was publicly identified as Guilherme’s wife during his successful 2019 season with Sport Recife.
The couple have therefore shared many significant periods of his professional career, including his years in Brazil and his moves abroad.
Tainá has generally maintained a lower public profile than her husband, but when she has spoken publicly, her comments have emphasized family unity and supporting Guilherme through the highs and lows of football.
How Many Children Does Guilherme Augusto Have?
Guilherme Augusto and Tainá have two children: Pietra and Guilherme Júnior.
Both children have become familiar faces to supporters of several clubs their father has represented because Guilherme regularly brings them onto the pitch after matches or during important club events.
Guilherme has said that walking onto the field with his children gives him peace, confidence and a reminder of the entire family supporting him behind the scenes.
Pietra
Pietra is Guilherme and Tainá’s eldest child.
Guilherme has spoken especially warmly about how becoming Pietra’s father changed his outlook on life.
During his time with Sport Recife in 2019, he described Pietra as a gift from God and explained that becoming a father completely changed his priorities.
According to Guilherme, things that once seemed extremely important became less significant because his attention naturally shifted toward his daughter and family.
Pietra also developed a particularly strong relationship with football supporters.
During Guilherme’s period at Sport Recife, fans affectionately regarded her as something of a lucky charm because she regularly accompanied her father onto the pitch.
That tradition continued as Guilherme moved between different clubs.
During his time with Santos, Pietra again became popular with supporters and frequently appeared alongside her father at Vila Belmiro.
In July 2024, Pietra even narrated one of her father’s goals during television coverage after Santos defeated Ituano.
Guilherme later dedicated the goal to both Pietra and her younger brother.
Guilherme Júnior
Guilherme Júnior is Guilherme and Tainá’s younger child.
His arrival was publicly discussed by his father in September 2019, when Guilherme said that Tainá was expecting their second child.
Guilherme Júnior, often affectionately called Gui, later became another regular presence around his father’s football career.
Like his older sister, he frequently accompanied Guilherme at club events and matches.
One particularly memorable story involving Guilherme Jr. came during Santos’ match against Palmeiras in January 2025.
After scoring, Guilherme celebrated by imitating one of Neymar’s famous gestures.
The forward later revealed that the celebration had been requested by Guilherme Jr., who was a major Neymar fan.
Guilherme joked that according to his son, Neymar was the second-best player in the world because his father naturally occupied first place.
How Guilherme Augusto’s Children Influence His Goal Celebrations
Both Pietra and Guilherme Jr. have directly inspired some of their father’s celebrations.
During the January 2025 match against Palmeiras, Guilherme Jr. inspired his father to imitate Neymar.
Pietra inspired another gesture in the same celebration because she enjoyed drawing and had asked her father to pretend to write or draw after scoring.
The moment demonstrated how closely Guilherme connects his football career with his role as a father.
Rather than keeping his professional and family lives completely separate, he often uses major football moments to acknowledge his children.
How Important Is Family to Guilherme Augusto?
Guilherme has described his family as his principal foundation away from football.
In a detailed interview during his time with Santos, he explained that entering the field with Pietra and Guilherme Jr. represents much more than simply having his children beside him.
For Guilherme, the children symbolically represent his wife, parents, siblings, in-laws and other relatives who support him.
He said their presence gives him peace, confidence and positive energy before matches.
That family support has been particularly important during difficult stages of his career when criticism from supporters and pressure surrounding performances affected him emotionally.
Who Are Guilherme Augusto’s Parents?
Guilherme Augusto has publicly referred to his mother and father as important members of his family, but their names have not been reliably disclosed by the strongest publicly available football sources.
Guilherme was born on April 13, 1995, in São Paulo state and grew up in the São Paulo metropolitan area.
His football journey eventually took him away from home as he entered youth football and pursued the opportunity to become a professional player.
Despite spending long periods away, Guilherme has continued mentioning his parents when discussing the people who provide emotional support throughout his career.
Guilherme Augusto’s Mother
The name of Guilherme Augusto’s mother has not been prominently documented by reliable major sports sources.
However, Guilherme has publicly thanked his mother during important achievements.
After winning individual honors at the 2025 Campeonato Paulista awards ceremony, Guilherme specifically thanked God, his children, wife and mother while discussing the achievement.
The public acknowledgment demonstrated that his mother continues to occupy an important place in his personal support system.
Because her name and private background have not been clearly documented, it would be inappropriate to identify her based on unverified online information.
Guilherme Augusto’s Father
Guilherme Augusto’s father has also remained outside the public football spotlight.
Reliable profiles do not provide his name, occupation or detailed personal background.
Guilherme has nevertheless included his parents collectively when discussing the relatives represented by his children whenever they accompany him onto the pitch.
That suggests that both his father and mother have remained part of the wider family network surrounding his career.
Does Guilherme Augusto Have Siblings?
Yes. Guilherme Augusto has publicly confirmed that he has siblings.
During his 2024 interview about family life, Guilherme referred to his “brothers and sisters” or siblings collectively while explaining that Pietra and Guilherme Jr. represent the entire family when they accompany him onto the field.
However, reliable mainstream sources have not clearly identified those siblings by name or documented how many brothers and sisters he has.
For that reason, it is more accurate to confirm that Guilherme has siblings without attempting to name or count them using uncertain online information.
Guilherme Augusto’s Family During His Time at Sport Recife
Guilherme’s 2019 season with Sport Recife provides some of the earliest detailed public information about his family life.
He enjoyed one of the strongest seasons of his career, finishing as the leading goalscorer in Brazil’s Série B.
Pietra regularly attended matches and quickly became popular among Sport supporters.
At the same time, Guilherme and Tainá were preparing for the arrival of Guilherme Jr.
The striker openly discussed how fatherhood had changed him and how returning home to his family helped him deal with the pressures associated with professional football.
Guilherme Augusto’s Family During His Years Abroad
Guilherme later left Brazil to continue his career in the Middle East.
He joined Al-Faisaly in Saudi Arabia in 2020 and subsequently represented Al-Dhafra in the United Arab Emirates.
Those moves introduced another challenge for the family because they had to adapt to life far away from Brazil.
Guilherme eventually returned to Grêmio in 2022 before continuing his career with Fortaleza.
Tainá Supported Guilherme During a Difficult Fortaleza Season
Guilherme’s 2023 season with Fortaleza initially included significant criticism.
Some supporters questioned his performances, creating a difficult emotional period for the player and his household.
Tainá later explained that the criticism affected the family but that she and the children continued encouraging Guilherme.
His form eventually improved dramatically.
Guilherme became one of Fortaleza’s leading goalscorers during its historic Copa Sudamericana campaign and helped the club reach the continental final.
Tainá, Pietra and Guilherme Jr. traveled to Uruguay for the final against LDU, allowing the family to experience one of the biggest matches of his career together.
Guilherme Augusto’s Family at Santos
Guilherme joined Santos ahead of the 2024 season and immediately brought his family into the experience.
Before completing the transfer, he showed the Santos mascots to Pietra and Guilherme Jr. to see how they reacted.
The children quickly became excited about the club, helping make Guilherme feel increasingly comfortable with the possibility of joining Santos.
After the move became official, both children appeared during his presentation and quickly became popular with people around the club.
Guilherme later said that his children adapted extremely quickly wherever his football career took the family, making major career transitions easier for him and Tainá.
Living Closer to Guilherme’s Extended Family
Playing for Santos also brought Guilherme geographically closer to much of his extended family.
Having grown up in the São Paulo region, his move to Santos meant his parents, siblings, in-laws, relatives and longtime friends could attend more matches.
Guilherme noted that his extended family attended almost every possible match during the early months of his Santos career.
The closeness was particularly meaningful after several years playing far from São Paulo and even outside Brazil.
Guilherme Augusto’s Move to Houston Dynamo FC
Another major family change arrived in January 2026 when Guilherme left Santos and joined Houston Dynamo FC in Major League Soccer.
The move represented the third international chapter of his professional career following earlier experiences in Saudi Arabia and the United Arab Emirates.
Houston signed Guilherme permanently from Santos as a Designated Player.
The Dynamo publicly welcomed Guilherme and his family to Houston, recognizing that his wife and children would also be adapting to another new country.
Guilherme signed a contract running through the 2027-28 season, with a club option for the 2028-29 season.
