Thomas Boone Quaid is best known as the son of American actor Dennis Quaid and his former wife, Kimberly Buffington. Born into a well-known Hollywood family, Thomas has attracted public interest because of his father’s successful acting career. However, unlike his older half-brother, Jack Quaid, Thomas has largely stayed away from the entertainment industry.
Thomas was born in November 2007 alongside his twin sister, Zoe Grace Quaid. His early life also became widely discussed after he and Zoe experienced a serious medication error as newborns. Both children recovered, and the incident later became part of a broader conversation about patient safety in hospitals.
As of 2026, Thomas is entering adulthood and beginning his college journey. Here is what is publicly known about his age, family, education, childhood, and life beyond Hollywood.

Who Is Thomas Boone Quaid?
Thomas Boone Quaid is one of three children of actor Dennis Quaid. His father has appeared in numerous successful films, including The Parent Trap, The Day After Tomorrow, The Rookie, and The Right Stuff.
Thomas became known to the public because of his family background rather than a career in acting. While his half-brother Jack followed their father’s path into entertainment, Thomas has maintained a more private life.
Most information about Thomas comes from family interviews and news reports about Dennis Quaid. He has not established a widely documented public career, and details about his personal interests, friendships, and future ambitions remain limited.
In 2026, Thomas entered a new stage of life after finishing high school and beginning college. This milestone brought renewed attention to Dennis Quaid’s younger children as they moved toward adulthood.
How Old Is Thomas Boone Quaid?
Thomas Boone Quaid was born on November 8, 2007. He is 18 years old in October 2026 and will celebrate his 19th birthday in November.
His birthday is shared with his twin sister, Zoe Grace Quaid. The twins were born in Santa Monica, California, through a gestational carrier.
Thomas spent his childhood largely outside the regular Hollywood spotlight. Although his father is a well-known actor, the family has generally kept many details about the twins’ daily lives private.
His age became particularly relevant in 2026 because both twins graduated from high school and began their next stage of education. Thomas is now attending the University of Colorado Boulder, according to recent media reports.
Who Are Thomas Boone Quaid’s Parents?
Thomas’s parents are Dennis Quaid and Kimberly Buffington. His father is an established American actor, while his mother has worked in real estate.
Dennis and Kimberly married in July 2004. They welcomed their twins in November 2007 and later experienced a series of separations and reconciliations before their divorce was finalized in 2018.
Although their marriage ended, both parents have remained part of their children’s lives. Their family has attracted attention because of Dennis’s public career, but the twins themselves have generally been kept out of extensive media coverage.
His Father, Dennis Quaid
Dennis Quaid was born on April 9, 1954, in Houston, Texas. He developed a long career in film and television, appearing in dramas, comedies, sports films, and family movies.
Some of his best-known films include The Right Stuff, The Parent Trap, Frequency, The Day After Tomorrow, and The Rookie. His performances have helped establish him as a familiar face in American entertainment.
Dennis has also spoken publicly about fatherhood and the importance of his children. In interviews, he has expressed pride in all three of his children: Jack, Thomas, and Zoe.
Thomas’s relationship with his father is part of his public biography, although the family has not disclosed every aspect of their private relationship.
His Mother, Kimberly Buffington
Kimberly Buffington is a real estate professional from Texas. She married Dennis Quaid in 2004, and their twins were born three years later.
The couple’s relationship went through several changes before their divorce was finalized in 2018. Following their separation, they continued sharing parental responsibilities for Thomas and Zoe.
Kimberly has maintained a lower public profile than Dennis. Most media coverage about her focuses on her marriage, divorce, and family life.
Thomas’s mother has played an important role in his upbringing, but details about her private relationship with him are not extensively documented.
Thomas Boone Quaid and His Twin Sister, Zoe Grace Quaid
Thomas has a twin sister named Zoe Grace Quaid. They were born on November 8, 2007, and grew up together as Dennis and Kimberly’s youngest children.
The twins attracted public attention shortly after birth because of a serious medical emergency involving an accidental medication overdose at the hospital. Both survived the incident and recovered.
As they grew older, their parents generally kept them away from the constant media attention that often surrounds celebrity families.
In 2026, Thomas and Zoe reached an important shared milestone by graduating from high school. However, they chose different colleges for their next stage of education.
According to recent reporting, Thomas enrolled at the University of Colorado Boulder, while Zoe planned to attend the University of Virginia.
Their educational choices show that the twins are beginning to establish their own paths as young adults. Beyond these reported milestones, information about their individual interests and future plans remains private.
Thomas Boone Quaid’s Older Half-Brother, Jack Quaid
Thomas has an older half-brother, Jack Quaid, from Dennis Quaid’s previous marriage to actress Meg Ryan.
Jack was born on April 24, 1992, and has established a professional acting career. He is known for appearing in projects such as The Hunger Games, The Boys, and Scream.
Unlike Thomas, Jack works in the entertainment industry and has developed a public identity independent of his parents. His acting career has brought him considerable attention from audiences and entertainment media.
Thomas and Jack have different mothers but share the same father. This makes Jack Thomas’s paternal half-brother.
Although their professional paths differ, both are part of Dennis Quaid’s family. The limited public information about their private relationship means it would be inappropriate to make assumptions about how often they spend time together or how they interact outside public events.
Thomas Boone Quaid’s Childhood Medical Emergency
One of the most widely reported events in Thomas’s early life occurred shortly after he and Zoe were born in November 2007.
The twins were hospitalized and mistakenly given an excessive dose of heparin, a blood-thinning medication. Reports at the time described the error as potentially fatal.
Heparin is used in medical settings for specific purposes, but the wrong dose can cause serious bleeding complications. The medication error placed both newborns at risk and led to extensive media coverage.
Dennis Quaid and Kimberly spoke publicly about the experience. The incident also contributed to discussions about medication labeling, hospital procedures, and patient safety.
What Happened After the Medication Error?
Thomas and Zoe recovered from the incident. Their family subsequently became involved in efforts to raise awareness about medical errors and patient safety.
Dennis Quaid helped establish the Quaid Foundation, which focused on improving awareness of preventable medical mistakes and encouraging safer healthcare practices.
The family’s experience highlighted how medication errors can affect patients and their relatives. It also drew attention to the need for clear labeling, effective safety checks, and reliable hospital procedures.
Thomas was a newborn at the time, so he has not publicly provided his own account of the incident. Most available information comes from statements made by his parents and contemporary news coverage.
The event remains a notable part of his biography, but it should not define his entire life. He has since grown up, completed high school, and begun college.
Thomas Boone Quaid’s Education
Thomas’s education became a subject of public interest when news reports announced that he had graduated from high school in 2026.
According to People, Thomas graduated in June and subsequently began attending the University of Colorado Boulder. His twin sister, Zoe, also graduated in 2026 and planned to attend the University of Virginia.
These reports provide a clear picture of his latest publicly documented educational milestone. However, detailed information about his earlier schools, grades, extracurricular activities, and academic achievements has not been widely published.
Why Did Thomas Choose the University of Colorado Boulder?
Thomas’s enrollment at the University of Colorado Boulder has been reported, but his personal reasons for choosing the university have not been clearly established in public sources.
It would therefore be inaccurate to claim that he selected the school for a particular degree, career plan, or personal interest without confirmation.
College is an important transition for many young adults. It can provide opportunities to study a subject, meet new people, develop independence, and explore possible career paths.
Thomas is beginning this stage of life while remaining largely outside the entertainment spotlight. Whether he eventually pursues a career in business, entertainment, or another field has not been publicly confirmed.
Is Thomas Boone Quaid an Actor?
There is no well-established public record of Thomas Boone Quaid having a professional acting career as of October 2026.
His father, Dennis Quaid, has worked in film and television for decades, and his half-brother Jack is also an actor. However, family connections do not necessarily determine an individual’s professional interests.
Thomas has not been widely credited for film or television roles in reliable public sources. Recent reporting about him focuses on his family and education rather than entertainment projects.
It remains possible that he could pursue acting or another public career in the future, but there is no reliable basis for predicting his professional direction.
For now, his best-documented role in the public record is that of Dennis Quaid’s son and a college student beginning adulthood.
Thomas Boone Quaid’s Net Worth
Thomas Boone Quaid’s personal net worth is not publicly established. There are no reliable financial disclosures or verified reports that provide an accurate estimate of his assets, income, or investments.
Some celebrity biography websites assign estimated wealth figures to the children of famous actors. However, these numbers are often published without a transparent calculation or reliable supporting evidence.
His father’s wealth should not be confused with Thomas’s own net worth. Dennis Quaid has earned income through acting and other professional activities, but that does not establish the value of his son’s personal finances.
Thomas is a young adult who has only recently begun college. His future career and income, if any, have not been publicly documented in detail.
The most accurate approach is to say that his personal net worth is unknown rather than repeat an unsupported figure.
What Is Thomas Boone Quaid Doing Now?
As of 2026, Thomas is beginning his college years at the University of Colorado Boulder. This development was reported after he completed high school in June.
His father discussed the twins’ transition to college in an interview with People, describing the experience of sending them out into the world as they began their adult lives.
Thomas has not developed a highly visible social media or entertainment profile, and reliable details about his daily routine remain limited.
His current stage of life is centered on education and the transition to greater independence. Beyond his college enrollment, there is not enough verified information to describe his schedule, social life, or future career plans confidently.
As he grows older, he may choose to remain private or become more publicly active. For now, available information suggests that he is focused on his education rather than pursuing a public entertainment career.
Why Is Thomas Boone Quaid Famous?
Thomas is mainly known because he is the son of Dennis Quaid. His father has a long career in Hollywood, making the family name familiar to film audiences.
His early medical emergency also brought public attention to the family in 2007. The incident became part of wider discussions about medication safety and the prevention of medical errors.
More recently, interest in Thomas has increased as he and his twin sister have graduated from high school and moved on to college.
Despite this attention, Thomas has not established an independent celebrity profile. Most of the available information about him comes from reporting about his father and family milestones.
His biography is therefore different from that of an actor or influencer whose professional work is regularly covered by the media.
Conclusion
Thomas Boone Quaid is the son of actor Dennis Quaid and real estate professional Kimberly Buffington. Born on November 8, 2007, he grew up alongside his twin sister, Zoe Grace, and his older half-brother, Jack Quaid. His infancy became widely discussed after a serious hospital medication error, but both twins recovered.
In 2026, Thomas graduated from high school and began attending the University of Colorado Boulder. Unlike his father and half-brother, he has no established public acting career. He continues to maintain a relatively private life as he begins adulthood.
