Thomas Boone Quaid is the son of actor Dennis Quaid and Kimberly Buffington, and the twin brother of Zoe Grace Quaid. The story of Thomas Boone Quaid and Dennis Quaid is mostly a family story: born in 2007, known first through a hospital error his father later campaigned over, and since then almost entirely out of sight. If you’re asking who is Thomas Boone Quaid now, he’s an 18-year-old with a famous surname and no public career, and most pages offering a Thomas Boone Quaid age beyond that, or a Thomas Boone Quaid net worth, are guessing.
He turns up in search results for two reasons. One is the surname. The other is the 2007 medication error at a Los Angeles hospital that his father has talked about publicly for years. Put the two together and you get a steady stream of near-identical biography pages, most of them repeating the same dozen facts and padding them with details nobody has sourced.
This profile sticks to what’s documented. He’s a young adult who has only just left childhood, so I’ve kept it to his birth, his family and the events his parents themselves made public. His school, his address, his friendships and his health today aren’t covered, because none of it is on the record and none of it is anyone else’s business.

Who Is Thomas Boone Quaid?
A private young man, and one half of a set of fraternal twins. Associated Press coverage from 2007 says the twins were born on November 8 to a surrogate mother, and that Dennis Quaid and his then-wife, Kimberly, are their biological parents. A 2010 AARP profile adds that the couple had spent three years trying to conceive before the surrogate pregnancy, and that the children are known as T. Boone and Z.G.
That’s the foundation. He isn’t an actor, a musician or an athlete that anyone has documented, and there’s no verified social media account to check his own words against.
Why Is Thomas Boone Quaid Famous?
Because of his father, and because of what happened to him as a baby.
Dennis Quaid has been a working star for decades, with a career that runs from The Right Stuff in 1983 to The Parent Trap in 1998 and well beyond. His name carries across several generations of film fans. The second reason is the medical error, which turned a private family into a patient-safety story and gave the twins a place in hospital-safety debates long before they could read.
Thomas Boone Quaid’s Parents
Dennis Quaid
Dennis Quaid is the actor, and the connection that makes this page worth searching for. He married Kimberly Buffington in 2004, according to ABC News and AARP, and he has been married several times. ABC and CBS list his earlier marriages to actress P. J. Soles, which ended in 1983, and to Meg Ryan, which ended in 2001.
He also became a public voice on patient safety after the twins’ hospital error, a role AARP described in a 2010 profile titled “Dennis Quaid Wants to Save Your Life”. That advocacy is the clearest example of a parent choosing to make a private event public.
Kimberly Buffington
Kimberly Buffington is Thomas’s mother, described in AARP’s 2010 profile as an Austin, Texas, real estate agent whom Quaid met in 2003. She has largely stayed out of the press. A divorce petition filed in Texas in March 2012 was reported by CBS and AP, with Quaid’s representatives saying a settlement was being worked out, and later coverage refers to a 2018 divorce agreement. The sources don’t line up neatly, so I’d treat the exact timeline as unclear.
Thomas Boone Quaid’s Siblings
Zoe Grace Quaid
Zoe Grace is his fraternal twin, born the same day. A few pages say Thomas arrived about two minutes before her, which is the kind of detail that appears in family profiles but rarely in primary coverage. She’s also a private person with no public career, and this page doesn’t profile her.
Jack Quaid
Jack Quaid is Thomas’s older half-brother, the son of Dennis Quaid and Meg Ryan and an actor best known for The Boys. AP reported in 2007 that Jack was 15 at the time, which puts the age gap at roughly 15 or 16 years. Jack is a public figure; Thomas isn’t, and the two shouldn’t be confused.
The 2007 Hospital Error
When the twins were about twelve days old, they were admitted to Cedars-Sinai Medical Center in Los Angeles for staph infections, on November 17, 2007, according to AARP. The mistake came to light on the morning of November 19, and AARP says their parents then stayed at the babies’ bedsides for the next 32 hours. AARP’s account says they were then accidentally given a dose of the blood thinner heparin that was roughly 1,000 times the correct amount. The hospital apologised, according to AP, and AARP says doctors gave both infants a drug to reverse the effects.
CBS News reported in 2012 that both twins had made a full recovery, and Dennis Quaid told Access Hollywood in January 2008 that they were doing great. The family reached a reported $750,000 settlement with the hospital, and also filed a separate lawsuit against the drug maker.
It’s a story the family told publicly and repeatedly, and I’m including it for that reason. What I’m not doing is guessing about his health since, which no source covers.
Is Thomas Boone Quaid an Actor?
No. Several profile pages call him a “child actor” simply because he’s part of an acting family, but none lists a role, a casting or a credit. Others say plainly that he has no known film career.
Unlike his half-brother, who has built a long acting résumé, he has no role listed anywhere I could find, not even a cameo. That sits well with the evidence. He’s appeared in photographs at family events and premieres as a small child, like many celebrity kids, and that’s about as far as it goes.
How Old Is Thomas Boone Quaid?
He’s 18 in 2026. AP reported the twins’ birth in November 2007, and several recent pages give his age as 18. I’m not giving his exact birth date here, since a young adult’s full birthday doesn’t help anyone understand the story.
What Is Thomas Boone Quaid Doing Now?
That’s mostly unknown. Several pages say he finished high school and has begun college, and one names a particular university and a field of study. None of them cites a source, and some read like template text, so I’ve left the specifics out. The only widely repeated point is that he lives a low-profile life.
What Is Thomas Boone Quaid’s Net Worth?
There isn’t a figure worth trusting. He has no career, no public earnings and no disclosed assets, and what his father or mother earn tells you nothing about him.
Any page that gives a number is guessing, and the more careful ones say outright that he has no publicly established net worth.
Where Does Thomas Boone Quaid Live?
There’s no reliable public information. A few pages name a city or a school, and I haven’t repeated them. A teenager who has only just become an adult shouldn’t have his whereabouts guessed at by a search-optimised article.
Rumours and Mistakes About Thomas Boone Quaid
A few errors keep circulating. He’s called a child actor, a “medical miracle” with a fixed life plan, and a student at a named college with a named major.
Ask where a detail first appeared. If the answer is another website that doesn’t say, nobody checked it.
Why Thomas Boone Quaid Stays Out of the Spotlight
I won’t invent a reason. Plenty of children of famous parents choose ordinary lives, and a family that has already told a very public medical story might reasonably prefer to keep the rest private. That’s a guess, though, and neither he nor his parents have said so.
Separating Facts From Myths About Thomas Boone Quaid
Reasonably well-supported: he is the son of Dennis Quaid and Kimberly Buffington, he was born in November 2007 through a gestational surrogate alongside his twin, Zoe Grace, and he’s 18 in 2026.
Weakly supported or unconfirmed: his school, his college plans, his relationships, his hobbies and his current whereabouts.
Not supported at all: that he’s an actor, that he has a specific college major, that he has a specific net worth, and any claim about his health today.

Why People Keep Searching for Thomas Boone Quaid
It comes down to the Quaid name. Every Dennis Quaid film, every Jack Quaid role and every story about the family sends a few readers looking for the twins, and in 2026 news about the family’s child-support arrangements added another reason. A young adult with almost no public footprint is exactly the sort of search that content farms love, because there’s demand and nothing on record to contradict whatever gets written.
That’s why so many of these pages sound alike. They’re answering a question the record can’t answer.
