Who Is Thomas Boone Quaid? The Life of Dennis Quaid’s Son

When you hear the name “Quaid,” you might instantly think of Hollywood. But not everyone in the Quaid family lives under the spotlight. One example? Thomas Boone Quaid. He’s the son of famous actor Dennis Quaid, but Thomas has chosen a very different path — one that’s quiet, private, and far from the cameras.

Let’s take a calm and simple walk through his early life, the big event that made national news when he was just a baby, and what makes his story so meaningful even today in 2026.

Quick Bio

A Special Beginning

Thomas Boone Quaid was born on November 8, 2007, in Santa Monica, California. He came into the world just two minutes before his twin sister, Zoe Grace Quaid. Their parents, actor Dennis Quaid and real estate agent Kimberly Buffington, had tried for a long time to have children. After several pregnancy challenges, they chose gestational surrogacy, which means another woman carried the babies for them. It was a long and emotional journey that ended with joy — and two healthy babies.

At birth, Thomas weighed 6 pounds and 12 ounces, and Zoe weighed 5 pounds and 9 ounces. They were strong, healthy, and their arrival brought big smiles to their parents’ faces. But just ten days later, everything suddenly changed.

The Scary Hospital Mistake

When Thomas and Zoe were just ten days old, they had a minor staph infection and were taken to Cedars-Sinai Medical Center for treatment. What happened next was something no parent could ever imagine. A serious hospital mistake almost cost them their lives.

Instead of giving the twins the correct 10 units of Heparin (a blood thinner), the hospital gave them 10,000 units — that’s 1,000 times the safe dose. It was an adult dose, not made for tiny babies. As a result, their blood became dangerously thin — some doctors described it as turning to the “consistency of water.”

This mistake led to severe internal bleeding, and both babies were in critical condition. It was a terrifying time for their parents. They rushed to the hospital, only to find their newborns hooked up to wires and machines. The future was uncertain.

But somehow, with fast medical care and strong little bodies, Thomas Boone Quaid and his sister survived.

A Full Recovery and a Strong Family

By December 2007, just a month later, both babies had fully recovered. There were no long-term injuries or effects. It was truly a miracle — and their parents knew it.

After this experience, Dennis Quaid didn’t just move on. Thomas spoke up, He talked about the event on TV, in interviews, and even went to Congress to raise awareness. He wanted hospitals to fix their labeling, make medications safer, and help other families avoid the pain he went through.

Thomas even made a documentary called Chasing Zero: Winning the War on Healthcare Harm, which explained how simple mistakes in hospitals can have big, life-changing effects. All of this happened because of what happened to Thomas.

So while Thomas Boone Quaid was just a baby at the time, his survival helped change hospital safety laws, raise awareness, and even save lives.

Growing Up in a Private World

Now in 2026, Thomas is 18 years old. He lives a quiet life in Los Angeles, far away from the Hollywood spotlight his family is known for. After Dennis Quaid and Kimberly Buffington divorced in 2018, Thomas stayed mostly with his mother, who has 75% physical custody. His dad still plays a big role in his life, but the daily routine happens mostly with his mom and his twin sister.

Unlike many kids born into famous families, Thomas Boone Quaid doesn’t have public social media. You won’t find him on Instagram or TikTok sharing his day. And you likely won’t see him in movies, either. Even though his half-brother Jack Quaid is a big-time actor in shows like The Boys, Thomas isn’t following that same path.

Staying Away from the Spotlight

As Thomas Boone Quaid got older, many people wondered if he would become an actor like his dad or his half-brother Jack. But the answer was clear: Thomas doesn’t want a Hollywood life. He doesn’t go to acting classes. He doesn’t go to big red-carpet events unless it’s with his dad. And he doesn’t want to be in the news or on social media.

He enjoys his own space. He likes living like a regular person, even though he comes from a famous family. That’s something rare. A lot of kids born into fame try to be famous too. But Thomas Boone Quaid is different. He’s chosen to live quietly, and his family supports that.

A Close Bond with His Twin Sister

Thomas shares something very special — a birthday and a life journey — with his twin sister, Zoe Grace Quaid. They were born just two minutes apart. And they survived the same scary hospital mistake as babies. That kind of experience can connect two people deeply.

They’ve grown up together, side by side. They go to the same schools, share the same home, and understand each other in a way only twins can. In 2025, Zoe was even working as a camp counselor in Texas, which shows she’s also growing into her own person.

Even if they don’t share everything with the world, Thomas and Zoe are very close — not just as siblings, but as true friends.

Family Life After Divorce

Thomas’s parents, Dennis Quaid and Kimberly Buffington, officially divorced in 2018. It wasn’t always easy. They had a few separations before they made the final decision. But even after they split up, both parents stayed committed to raising their children well.

Thomas lives mostly with his mom in Los Angeles, where she has 75% physical custody. His dad, Dennis, still sees him and plays an important role. Even after the divorce, the family worked hard to stay peaceful and kind. That has helped Thomas feel safe and supported as he grows up.

His Relationship with Jack Quaid

You may know Jack Quaid from popular shows like The Boys or The Hunger Games. He’s Thomas’s half-brother, and he’s much older. Jack is the son of Dennis Quaid and Meg Ryan, another famous actor.

Even though they live very different lives, Jack and Thomas have a good relationship. Jack has spoken kindly about being a big brother. And Dennis has said that Jack is a great example for his younger siblings.

Still, Thomas has not followed in Jack’s footsteps. While Jack accepted the “nepo baby” label and used it to build a strong career, Thomas Boone Quaid chose to stay out of the spotlight. That’s his choice, and his family respects it.

A Quiet, Grounded Teen Life

So what does Thomas Boone Quaid enjoy doing today? He’s still in school, working hard on his education. He attends private school in Los Angeles, but the name of the school is kept private — just to keep things safe and calm.

Thomas’s described by family as a kind, thoughtful, and smart young man. He’s not chasing fame, He’s not trying to impress the world, He’s just growing up with love, balance, and privacy.

People who know him say he enjoys creative things, maybe like music or photography. But he hasn’t shared any big plans yet. Maybe he will in the future — or maybe not. Either way, he has the freedom to choose his own path.

What the Future May Hold

Right now, Thomas is 18 years old. He’s finishing high school and getting ready to take his next big step. Will he go to college? Maybe. Will he choose a quiet job far from cameras? That’s possible too.

The best part is that Thomas Boone Quaid doesn’t have to rush. His family has made sure he has support, stability, and time to find out what makes him happy.

He’s not just “Dennis Quaid’s son.” He’s his own person — a young man who survived something scary, grew up in a strong family, and now gets to build his own life in his own way.
