Thomas Boone Quaid is the younger son of actor Dennis Quaid and real estate professional Kimberly Buffington. He was born on November 8, 2007, alongside his twin sister, Zoe Grace Quaid, and became publicly known because of his famous family and a serious hospital medication error that nearly killed both twins shortly after birth. As of July 2026, Thomas Boone Quaid is 18 and has completed high school, but he continues to live largely outside the entertainment spotlight.
Unlike his older half-brother Jack Quaid, Thomas has not built a public acting career. Reliable reporting shows no verified movie or television credits under his name, and no confirmed height, personal net worth, relationship, or professional income. Current profiles of Dennis Quaid’s children identify Jack as the professional actor while describing Thomas and Zoe primarily through their family background and recent graduations.

Thomas Boone Quaid’s Early Life
Thomas was born in Santa Monica, California, through a gestational carrier. He arrived at 8:26 a.m. and weighed 6 pounds, 12 ounces. Zoe Grace was born two minutes later and weighed 5 pounds, 9 ounces. Their parents later testified that the twins were four weeks premature but healthy enough to go home after three days.
Dennis was already known for films including The Right Stuff, The Parent Trap, Frequency, and The Rookie. Kimberly worked in real estate and was his third wife. They married in 2004 and finalized their divorce in 2018.
The Medical Crisis After His Birth
When Thomas and Zoe were 11 days old, their parents noticed signs of irritation and took them for medical evaluation. Tests at Cedars-Sinai Medical Center showed that both babies had staph infections, so doctors admitted them for intravenous antibiotics. During that hospitalization, staff mistakenly administered 10,000 units of heparin instead of the intended 10-unit dose used to flush their IV lines.
The dose was 1,000 times stronger than intended. Dennis and Kimberly later testified that the twins received another high-dose injection that evening, leaving them at severe risk of uncontrolled bleeding and organ damage. The family said they were not informed until the next morning, although staff had already noticed abnormal bleeding.
Doctors used protamine to counteract the heparin, and the twins’ clotting levels eventually returned to the normal range after more than 40 hours. They survived and were discharged in early December 2007. Early reports described a full recovery, while the parents initially acknowledged that long-term effects could not yet be known.
The case became a national patient-safety story. California regulators fined Cedars-Sinai $25,000, and the hospital reviewed procedures involving high-risk drugs. Dennis and Kimberly later gave congressional testimony about medication safety and patient rights.
Thomas did not personally become a public advocate. He and Zoe survived an error that became a widely reported example of the need for stronger medication safeguards. Dennis later established the Quaid Foundation to increase awareness of preventable medical mistakes.
Twin Thomas Boone Quaid and Zoe Grace Quaid
The phrase twin Thomas Boone Quaid refers to his close connection with Zoe Grace. They share the same birthday, early medical ordeal, and public family history. Most established reports discuss the twins together because the major events of their early lives happened at the same time.

Zoe joined Dennis at the Los Angeles premiere of Reagan in August 2024, while Thomas has made fewer recent public appearances.

Recent reporting says both twins completed high school in 2026.
