Quentin Grimes comes from an athletic family in which basketball and professional sports have played a major role. Born on May 8, 2000, in Houston, Texas, the Los Angeles Lakers guard is the son of former college basketball players Marshall Grimes and Tonja Stelly. His family also includes his older maternal half-brother, longtime NHL defenseman Tyler Myers.
Grimes’ parents helped introduce him to basketball at an early age, while Myers provided another example of what life as a professional athlete required. Together, Quentin and Tyler eventually made sporting history as the first brothers to play in the NBA and NHL. Here is everything known about Quentin Grimes’ girlfriend, children, parents and siblings.
Does Quentin Grimes Have a Girlfriend?
As of now, Quentin Grimes has not publicly confirmed having a girlfriend. The NBA guard keeps his romantic life extremely private, and there is no reliable public information identifying a current partner.
Although Grimes has become increasingly prominent during his NBA career, he has generally kept interviews and his public presence focused on basketball, his teammates and his family rather than his dating life.
Because Grimes has not announced a relationship himself, reports or social-media speculation claiming to identify his girlfriend should be treated cautiously unless supported by reliable sources.
Does Quentin Grimes Have Children?
There is no reliable public information indicating that Quentin Grimes has any children. He has not publicly announced becoming a father, and established biographical profiles about the basketball player do not identify any sons or daughters.
As of now, Grimes appears to keep much of his life outside basketball private.
Who Are Quentin Grimes’s Parents?
Quentin Grimes’ parents are Marshall Grimes and Tonja Stelly. Both have competitive sports backgrounds, particularly in basketball, making athletics an important part of Quentin’s upbringing.
His parents did not force him to specialize in basketball from an early age. Instead, they encouraged him to experience other sports before Quentin ultimately decided that basketball was the game he wanted to pursue seriously.
Quentin Grimes’s Father: Marshall Grimes
Quentin’s father, Marshall Grimes, played college basketball before his son’s birth. He competed at Santa Clara and later played at Louisiana, giving him firsthand knowledge of high-level basketball.
Marshall became an important influence on Quentin’s development. When Quentin was young, father and son would watch basketball games featuring stars from earlier generations, including Michael Jordan and Magic Johnson. They would then work together on different moves on the basketball court.
One particularly important stage came around Quentin’s middle-school years. Marshall helped change his son’s shooting mechanics, encouraging him to develop a higher release point. That shooting technique eventually became one of Quentin’s defining skills as he developed into an elite high school prospect and later an NBA guard.
Marshall never tried to take complete control of his son’s basketball development. Instead, he provided guidance and resources while allowing Quentin’s own competitiveness and work ethic to drive his improvement.
Quentin Grimes’s Mother: Tonja Stelly
Quentin’s mother, Tonja Stelly, was also an athlete. She played college basketball and tennis at Fort Hays State in Kansas before later attending the University of Kansas.
Her athletic background is particularly notable because both of her sons eventually reached major professional sports leagues. Quentin became an NBA player, while his older half-brother Tyler Myers established a long career in the NHL.
Tonja has remained a visible supporter of both sons. She has attended their games and has spoken proudly about having two children competing at the highest levels of two different professional sports.
Quentin has jokingly credited his mother for the family’s athletic genetics. Her role also connects two very different sports stories: one son became an NBA guard, while the other grew into one of the NHL’s tallest defensemen.
Who Are Quentin Grimes’s Siblings?
Quentin Grimes has one publicly documented sibling, his older maternal half-brother Tyler Myers.
Myers and Grimes share the same mother, Tonja Stelly, but have different fathers. Tyler’s father is Paul Myers, while Quentin’s father is Marshall Grimes.
Tyler Myers
Tyler Myers was born on February 1, 1990, in Houston, making him approximately ten years older than Quentin. He became a professional ice hockey defenseman and has enjoyed a long NHL career.
Myers was selected 12th overall by the Buffalo Sabres in the 2008 NHL Draft. He quickly became one of the league’s most promising young defensemen and won the Calder Memorial Trophy as the NHL’s top rookie following the 2009-10 season.
He later played for the Winnipeg Jets and Vancouver Canucks before being traded to the Dallas Stars in March 2026.
Although Quentin and Tyler are brothers, they did not grow up in the same household. When Quentin was only a few months old, Tyler moved from Texas to Calgary with his father, Paul, where he continued developing as a hockey player.
The distance meant that the brothers spent relatively little time together during their childhood. However, they remained connected through family visits, telephone conversations and messages.
Their relationship became even stronger as Quentin began moving closer to a professional basketball career. Tyler was already an established NHL player and could offer his younger brother advice about professional sports, including nutrition, taking care of his body and dealing with the demands of a long season.
Quentin Grimes and Tyler Myers Made NBA and NHL History
Quentin Grimes and Tyler Myers have a particularly unusual place in North American professional sports history.
When Grimes reached the NBA after being selected in the first round of the 2021 NBA Draft, he and Myers became the first pair of brothers to play in the NBA and NHL.
The achievement was even more remarkable because they pursued entirely different sports. Myers became an elite hockey prospect after moving to Canada, while Grimes remained in Texas and concentrated almost exclusively on basketball.
Despite the different paths, both reached the highest professional league in their respective sports.
How Quentin Grimes’s Parents Influenced His Basketball Career
Quentin’s development as a basketball player was heavily influenced by growing up with two parents who understood competitive athletics.
His father had experience playing college basketball and worked with Quentin on the technical parts of his game. His mother had competed in both basketball and tennis and understood the discipline required to succeed as an athlete.
Rather than pushing Quentin toward professional basketball from childhood, his parents allowed him to decide how seriously he wanted to pursue the game. Quentin’s own motivation eventually became clear as he began spending increasingly more time training.
He emerged as one of the leading high school basketball prospects in the United States while playing for College Park High School in The Woodlands, Texas. He later played college basketball at Kansas before transferring to Houston, where he developed into an All-American and helped the Cougars reach the 2021 Final Four.
Grimes entered the NBA in 2021 and went on to play for several teams before joining the Los Angeles Lakers in 2026, extending a family sports story that already included his father’s college career and his brother’s lengthy NHL career.
