Who Is Thomas Boone Quaid?
Thomas Boone Quaid is one of Dennis Quaid’s three children. He was born alongside his twin sister, Zoe Grace, on November 8, 2007, in Santa Monica, California. The twins were born through a gestational carrier, with Dennis Quaid and Kimberly Buffington identified as their biological parents.
Thomas arrived first at 8:26 a.m., according to PEOPLE, with a reported birth weight of 6 pounds, 12 ounces. Zoe was born two minutes later.
Unlike his older brother Jack, who has developed a public acting career, Thomas has remained largely outside the entertainment spotlight. Recent coverage describes Dennis Quaid as being relatively private about his younger children, and there is no well-established public record of Thomas pursuing an acting career.
Thomas Boone Quaid’s Age
Thomas was born on November 8, 2007. That makes him 18 years old in September 2026 and due to turn 19 in November.
His age became especially relevant in 2026 because both Thomas and Zoe reached major milestones after finishing high school and moving into college.
PEOPLE reported in September 2026 that Dennis Quaid had recently dropped his twins off at college, describing Thomas as an 18-year-old beginning this next stage of life.
Who Are Thomas Boone Quaid’s Parents?
Thomas’s parents are actor Dennis Quaid and Kimberly Buffington, a Texas real-estate professional whom Quaid married in 2004. The couple later divorced, with their divorce finalized in 2018.
Dennis Quaid is also the father of Jack Quaid, his son with actress Meg Ryan. Jack was born in 1992 and later became an actor known for projects including The Hunger Games and The Boys. That makes Jack Thomas’s older paternal half-brother.
Dennis has spoken publicly about fatherhood over the years, including his pride in Thomas and Zoe. Still, the younger twins have generally had a much lower public profile than Jack.
Thomas Boone Quaid and His Twin Sister Zoe
Thomas and Zoe have been closely linked in public reporting simply because they are twins and grew up together in the Quaid family.
Their birth drew significant media attention in 2007. Weeks later, the newborn twins were hospitalized at Cedars-Sinai Medical Center after developing infections. During that hospitalization, they were accidentally given heparin at a concentration 1,000 times the intended level. State investigators later identified several medication-safety failures surrounding the incident.
The incident was serious, but the twins recovered. They were discharged from the hospital by early December 2007.
The episode also became part of Dennis Quaid’s public advocacy around patient safety. In 2008, Dennis and Kimberly reached a $750,000 settlement with Cedars-Sinai over the medication error, according to the Los Angeles Times.
For Thomas himself, however, there has been little public discussion of the event in adulthood. Most recent coverage has focused instead on his education and transition into college.
Where Does Thomas Boone Quaid Go to College?
As of 2026, Thomas Boone Quaid is attending the University of Colorado Boulder.
PEOPLE reported in September 2026 that Dennis Quaid had dropped Thomas off at college and that Thomas and Zoe were beginning separate university experiences. Thomas chose the University of Colorado Boulder, while Zoe is attending the University of Virginia.
The move represents one of the clearest publicly reported milestones in Thomas’s life since childhood. It also marks a shift away from being primarily known as one of Dennis Quaid’s young twins and toward adulthood.
Does Thomas Boone Quaid Act?
There is no established public acting career for Thomas Boone Quaid.
That distinction matters because his older half-brother Jack followed Dennis Quaid and Meg Ryan into Hollywood. Jack has worked extensively as an actor, while Thomas has largely stayed out of public entertainment coverage. PEOPLE has specifically noted that Dennis rarely discusses his younger children publicly.
There is also no reliable evidence establishing that Thomas currently works as an actor, musician, filmmaker, or other entertainment professional. His publicly reported focus in 2026 is college.
What Is Thomas Boone Quaid’s Net Worth?
There is no reliable, independently verified public figure for Thomas Boone Quaid’s personal net worth.
Online celebrity sites sometimes assign net-worth figures to people who have never publicly disclosed their finances. Those estimates should not be treated as established facts, particularly in Thomas’s case because he has not built a documented public career with known earnings.
It is more accurate to describe him as the son of a successful actor than to attach a speculative dollar amount to his own wealth.
What Is Known About Thomas Boone Quaid’s Private Life?
Very little beyond major family milestones has been reliably documented.
Thomas has grown up in a highly recognizable Hollywood family, but public reporting has generally respected the distinction between his father’s celebrity and his own limited public profile. Recent coverage has centered on events such as high school graduation and college rather than relationships, daily activities, or a personal career.
That means claims about Thomas’s romantic life, personal interests, future career plans, or private finances should be approached cautiously unless they come from a credible, attributable source.
Thomas Boone Quaid in 2026
At 18, Thomas Boone Quaid is entering adulthood at a different pace from his famous older brother.
The major publicly documented developments in 2026 are straightforward: he completed high school, moved on to college, and began studying at the University of Colorado Boulder. His father has described the transition to college as an emotional milestone as both twins become more independent.
For now, that is where the reliable public record largely ends. Thomas remains known primarily through his family connection to Dennis Quaid, rather than through a professional career or extensive public presence of his own.
