Thomas Boone Quaid is the son of American actor Dennis Quaid and his former wife, Kimberly Buffington. He was born in 2007 and is the twin brother of Zoe Grace Quaid.
Unlike his father and older half-brother Jack Quaid, Thomas has mostly stayed away from the entertainment industry. Because he has grown up as a private person, only limited information about his personal and professional life is publicly available.
Early Life
Thomas Boone Quaid was born on November 8, 2007, in Santa Monica, California. He and his twin sister, Zoe Grace, were born through a gestational carrier.
Thomas was born first at 8:26 a.m. and weighed 6 pounds, 12 ounces. Zoe arrived two minutes later and weighed 5 pounds, 9 ounces. The twins are the youngest children of Dennis Quaid.
Their father is Dennis Quaid, a well-known American actor whose career includes films such as The Right Stuff, The Parent Trap, The Rookie, and Vantage Point.
Their mother, Kimberly Buffington, was married to Dennis Quaid from 2004 until their divorce was finalized in 2018.
Thomas Boone Quaid’s Family
Thomas comes from a family with strong connections to Hollywood.
His father, Dennis Quaid, has worked as an actor for decades. His older half-brother, Jack Quaid, is also an actor.
Jack was born in 1992 to Dennis Quaid and actress Meg Ryan. He later developed his own acting career and became known for projects such as The Hunger Games and The Boys.
Thomas’s twin sister is Zoe Grace Quaid. The two were born on the same day and have grown up together.
The Medical Emergency After Birth
One of the most widely reported events from Thomas’s childhood happened when he and Zoe were babies.
The twins were hospitalized at Cedars-Sinai Medical Center after developing staph infections. During their treatment, they were accidentally given a very large dose of the blood thinner heparin.
Reports stated that the twins received about 1,000 times the recommended dose. The mistake put both babies in serious danger.
Their parents later spoke publicly about the incident. The event also led Dennis Quaid to become involved in efforts to raise awareness about medical errors and patient safety.
The twins survived the incident and recovered. Later reports said they were discharged from the hospital after their condition improved.
It is important not to use this childhood event to make claims about Thomas’s current health. Reliable public sources do not establish a current medical condition related to the overdose.
Relationship With His Father
Dennis Quaid has spoken positively about his children over the years.
In 2026, he discussed his twins as they moved from high school into college. He said that Thomas and Zoe had started college and that he was proud of them.
Dennis has also described fatherhood as an important part of his life. His three children are Jack, Thomas, and Zoe.
Education
There is limited reliable information about Thomas’s earlier schooling.
The most recent public information is from 2026. Thomas graduated from high school that year and then moved on to college.
His high school graduation was an important family milestone. Dennis Quaid attended the graduation ceremony, and Kimberly Buffington was also present.
College and Field of Study
Thomas began college in 2026.
According to a recent PEOPLE interview with Dennis Quaid, Thomas is attending the University of Colorado Boulder and is studying business. His twin sister Zoe is studying business at the University of Virginia.
This is currently the clearest public information about Thomas’s education and future direction.
Career and Work
Thomas Boone Quaid does not have a publicly established professional career at this time.
There is no reliable evidence that he works as an actor, businessman, model, or other public professional. His current focus appears to be his education.
Because he has only recently started college, it would be incorrect to describe him as an established business owner or entrepreneur simply because he is studying business.
Business Interests
Thomas is studying business at the University of Colorado Boulder, but there is no reliable public information showing that he currently owns or operates a company.
Some websites may publish claims about celebrity children and their businesses without providing strong evidence. Those claims should not automatically be treated as facts.
At present, the safe and accurate statement is that Thomas is a college student studying business.
Acting Career
Thomas grew up in a family connected to the film industry, but there is no confirmed record of him building an acting career.
His father Dennis is an established actor, while his older half-brother Jack has also chosen acting as a profession.
Thomas appears to be taking a different path. His current public educational information points toward business rather than entertainment.
Life Away From the Spotlight
Thomas has generally lived a private life.
Unlike Dennis Quaid and Jack Quaid, he has not built a public career that requires regular media attention. As a result, information about his hobbies, friendships, dating life, private activities, and personal plans is limited.
This lack of information should not be filled with guesses.
For example, there is no reliable public information that confirms a girlfriend, wife, private business, personal income, or a specific social-media account.
Net Worth
Thomas Boone Quaid’s personal net worth is not reliably known.
He is a young college student and does not have a publicly documented professional career or business that would allow a trustworthy estimate.
For this reason, specific net-worth figures found on some biography websites should not be treated as confirmed information.
Height and Other Personal Details
A reliable public source does not provide Thomas’s current height.
The same applies to many other personal details, including his exact income, private interests, relationship status, and day-to-day activities.
A factual biography should leave these details out rather than present guesses as facts.
Current Life in 2026
Thomas is now 18 years old and has entered a new stage of his life.
He graduated from high school in 2026 and started college at the University of Colorado Boulder, where he is studying business. His move to college also marked a major change for his family because Dennis Quaid’s twins are now living more independently.
At this point, his future career is still developing. His business studies may lead him in many directions, but there is not enough public information to say what profession he will eventually choose.
Thomas Boone Quaid and Zoe Grace Quaid
Thomas and Zoe have shared many important stages of life as twins.
They were born only two minutes apart, experienced the serious medical emergency together as babies, grew up in the Quaid family, graduated from high school around the same time, and started college in 2026.
Their college paths are different. Thomas is attending the University of Colorado Boulder, while Zoe is attending the University of Virginia. Both are studying business.
What Is Known About His Future?
Thomas’s future career is not yet known.
His decision to study business gives some information about his current academic interests, but it does not prove that he will become an entrepreneur or work in a particular business field.
For now, the most accurate description is that he is a young college student beginning his adult life away from the Hollywood career followed by his father and older brother.
Final Thoughts
Thomas Boone Quaid has been connected to the public mainly because of his famous father, Dennis Quaid, and his family’s history.
His early life included a serious medical emergency involving a heparin overdose, but he and his twin sister survived and recovered. As he has grown older, Thomas has remained mostly private.
The latest confirmed information shows that he graduated from high school in 2026 and began studying business at the University of Colorado Boulder.
There is still little reliable information about his personal career, income, relationships, or business activities. Keeping those details out of a biography is important because a good profile should separate confirmed facts from online speculation. Visit for more details.
