Koby Brea’s rise from Washington Heights in New York City to the NBA is closely connected to his Dominican family roots. The Phoenix Suns guard was born to Dominican parents Mayra Villar and Stephan Brea, and he grew up in a family where basketball, culture and togetherness played major roles in his development.
Brea has repeatedly described his parents as two of the biggest influences in his life. His father was a basketball player himself, while his mother and siblings supported his journey through high school, Dayton, Kentucky and eventually the NBA. Here is everything publicly known about Koby Brea’s girlfriend, children, parents and siblings.
Who Is Koby Brea’s Girlfriend?
Koby Brea does not have a publicly confirmed girlfriend as of now. The basketball player has kept his romantic life largely outside the public spotlight, and reliable interviews, official biographies and major sports reports have not identified a girlfriend or partner.
Brea’s public profile has primarily focused on basketball and his family. Although athletes can choose to keep relationships private, there is currently not enough reliable information to name anyone as Koby Brea’s girlfriend.
For that reason, claims about his dating life that are not supported by Brea himself or credible reporting should be treated cautiously.
Does Koby Brea Have Children?
There are no publicly confirmed reports that Koby Brea has children.
His official college biographies and interviews discussing his personal life identify his parents and siblings but make no reference to him having a son or daughter.
As of now, Brea appears to be focused primarily on establishing himself in professional basketball with the Phoenix Suns.
Who Are Koby Brea’s Parents?
Koby Brea’s parents are Mayra Villar and Stephan Brea. Kentucky Athletics lists his father as Stephen Brea, while Dayton Athletics uses the spelling Stephan Brea. Both parents are originally from the Dominican Republic.
Brea has named his parents as the greatest influences in his life, and both played important roles in helping him pursue basketball from New York City all the way to the NBA.
Koby Brea’s Father: Stephan Brea
Stephan Brea is Koby Brea’s father. He is originally from Santiago in the Dominican Republic and has his own background in basketball.
Stephan played competitive basketball in the Dominican Republic and later participated in prominent basketball tournaments around New York City. Koby has explained that accompanying his father to games when he was young was one of the experiences that sparked his love for basketball.
Brea recalled watching his father play and later competing with him during pickup games. Those experiences helped develop both his skills and competitive mentality.
Stephan also played alongside or around former NBA player Felipe López, who became Koby’s godfather and an important basketball mentor.
Koby has spoken proudly about carrying his father’s name and influence throughout his basketball career. When Brea was selected in the 2025 NBA Draft, his father joined him for the emotional moment as his professional dream became reality.
Koby Brea’s Mother: Mayra Villar
Mayra Villar is Koby Brea’s mother. She is originally from Moca in the Dominican Republic.
Although considerably less has been publicly reported about Mayra’s professional life, Koby has consistently included his mother when discussing the people who made sacrifices for his basketball career.
She was with the family when Brea was selected in the second round of the 2025 NBA Draft. During his post-draft interview, Brea spoke about how happy he was that his parents could experience the achievement with him after everything they had done throughout his life.
His mother also helped keep the family’s Dominican identity strong while Koby was growing up in New York. That heritage later influenced his decision to represent the Dominican Republic internationally.
Who Are Koby Brea’s Siblings?
Koby Brea has three siblings: Tyler Villar, Javier Castillo and Stephen Dominguez, according to his official Kentucky basketball biography.
His earlier Dayton biography also listed three siblings named Tyler, Javier and Stephan. Brea grew up in a family environment that he has described as extremely close, particularly during holidays and other family gatherings.
Basketball also became part of that sibling relationship, with Brea recalling playing pickup games with his father and brother while developing his skills.
Tyler Villar
Tyler Villar is one of Koby Brea’s siblings. Very little verified information about Tyler’s personal or professional life has been made public.
Koby generally protects the privacy of family members who are not public figures, so details about Tyler remain limited.
Javier Castillo
Javier Castillo is another of Koby Brea’s siblings. Like Tyler, Javier has remained largely outside the public spotlight.
Official Kentucky Athletics information confirms the sibling relationship, but Brea has not extensively discussed Javier’s personal life in public interviews.
Stephen Dominguez
Stephen Dominguez is also listed as one of Koby Brea’s siblings.
One interesting detail from Brea’s official Kentucky profile is that he chose to wear jersey No. 4 because the number represents the day his younger brother was born. The biography does not explicitly identify which of his siblings is the younger brother associated with the number.
Koby Brea’s Dominican Family Heritage
Koby Brea was born in New York City, but his connection to the Dominican Republic has always been an important part of his identity.
Both of his parents were born in the Dominican Republic. His father comes from Santiago, while his mother is from Moca. Brea grew up in Washington Heights, an area of Manhattan known for its large Dominican community.
That environment allowed him to remain connected to Dominican culture even while growing up in the United States.
His heritage also gave him the opportunity to represent the Dominican Republic in international basketball. In 2019, Brea played for the country’s U17 national team at the Centrobasket Championship.
He has continued to speak proudly about representing the Dominican Republic, explaining that the support he receives from Dominican fans means a great deal to both him and his family.
How Koby Brea’s Father Inspired His Basketball Career
Koby Brea’s father was particularly important in introducing him to basketball. As a child, Brea regularly attended games and tournaments where Stephan competed.
Watching his father play helped create his interest in the sport, and the two later spent time playing basketball together.
Brea’s journey was not straightforward. He was initially cut from his high school basketball team before developing into a standout at Monsignor Scanlan High School in the Bronx.
He eventually received a scholarship from the University of Dayton, where he became one of college basketball’s most accurate three-point shooters. After four seasons at Dayton, he transferred to the University of Kentucky for the 2024-25 season.
His shooting ability helped him reach the 2025 NBA Draft, where the Golden State Warriors selected him with the 41st overall pick before his draft rights were traded to the Phoenix Suns.
