As Stephen Siller’s brother, he helped turn a deeply personal tragedy into a lasting mission supporting first responders, military members, veterans, and their families. Frank serves as the Chairman and CEO of the Tunnel to Towers Foundation, which was inspired by Stephen’s sacrifice on September 11, 2001. His story includes family, faith, leadership, and charitable service. In this article, we explore his biography, age, parents, religion, career, net worth, and the important work he continues through Tunnel to Towers.
Who Is He?
Frank Siller is a nonprofit executive and one of the founders of the Tunnel to Towers Foundation. The organization was created in memory of his younger brother Stephen, whose actions on September 11, 2001, became the inspiration for its mission.
Stephen was the youngest of seven Siller siblings. Frank has described him as the family’s younger brother and explained that there was a 14-year age difference between them. Stephen was an FDNY firefighter who had finished his shift on September 11 and was on his way to meet his brothers for golf when he heard about the attack. He turned around, returned toward Manhattan, and ran through the Brooklyn-Battery Tunnel with his firefighter gear.
Biography and Early Family Life
The Siller family was raised in Staten Island, New York, by George and Mae Siller. The couple had seven children, including Stephen and Frank. Their family life was strongly influenced by faith, family, service, and helping others.
Frank has spoken about how his parents shaped the values that later became central to his charitable work. George and Mae were members of the Third Order of St. Francis, and Frank has repeatedly connected the family’s philosophy of service with the words associated with St. Francis: “Let us do good.”
Stephen experienced the loss of both parents at a young age. Frank has explained that their older siblings played an important role in raising him after their parents died. Because of this close family relationship, Stephen’s death had a profound effect on Frank and the rest of the Siller family.
How Old Is He?
An exact current birth date for Frank Siller is not clearly established in the strongest publicly available sources. A 2021 Catholic News Service profile identified him as 68 at that time, which places his birth around 1952–1953.
Because public sources do not consistently provide a precise birth date, it is better not to publish an exact date of birth or a specific current age as an established fact unless a reliable primary source confirms it.
Who Are His Parents?
His parents were George and Mae Siller, who raised seven children. They are remembered not only as the parents of Stephen Siller but also for the values they passed to their children.
Tunnel to Towers named its scholarship program after Mae and George Siller. The foundation says the couple raised their children with values centered on faith, family, and service to others.
Their influence remains an important part of the Siller family’s charitable philosophy. Frank has frequently discussed how his parents encouraged their children to respond to hardship by doing something positive for others.
Relationship With Stephen Siller
Stephen Siller was Frank’s younger brother and the youngest of the seven Siller children. Frank has described Stephen as someone the family deeply loved and admired.
On September 11, 2001, Stephen had completed his overnight shift as an FDNY firefighter. After hearing that the World Trade Center had been attacked, he turned his vehicle around and headed toward the scene. When he reached the Brooklyn-Battery Tunnel, it was closed because of the emergency. Stephen then carried his firefighter equipment and ran through the tunnel toward the World Trade Center. He died that day while trying to help others.
For Frank, Stephen’s sacrifice became more than a family tragedy. It became the foundation for a mission that has continued for 25 years.
What Did He Do Before Tunnel to Towers?
Detailed information about Frank’s career before the creation of Tunnel to Towers is limited in reliable public sources. Available interviews and profiles focus much more heavily on his family, Stephen’s life, and the charitable work that followed the September 11 attacks.
An interview with Frank from 2020 shows that he and Stephen had also shared business and family conversations before 9/11, but it does not provide enough verified information to construct a detailed pre-Tunnel-to-Towers career history.
For that reason, claims about a specific former profession or business should not be presented as fact unless supported by a reliable source.
How Tunnel to Towers Began
The Tunnel to Towers Foundation grew directly out of the Siller family’s desire to honor Stephen and the other people who lost their lives on September 11.
Frank and his siblings wanted to create something positive from their loss. The foundation’s name comes from Stephen’s final journey through the Brooklyn-Battery Tunnel toward the World Trade Center.
The organization initially became associated with the Tunnel to Towers 5K Run & Walk, which retraced Stephen’s route. The first run took place in 2002 and attracted thousands of participants. Over the years, the foundation expanded far beyond the original event.
What Does the Foundation Do?
Today, the Tunnel to Towers Foundation supports several groups, including fallen first responder families, Gold Star families, military veterans, and catastrophically injured service members.
Its programs have included mortgage-free homes for families of fallen first responders and Gold Star families, as well as specially adapted smart homes for severely injured veterans. The foundation’s mission is built around honoring people who made significant sacrifices while serving their country and communities.
In 2026, the organization also launched the Mae and George Siller Scholarship Program to provide educational support for eligible children connected with the foundation’s programs.
Role as Chairman and CEO
Frank currently serves as Chairman and CEO of the Tunnel to Towers Foundation. The foundation’s official leadership page lists him as both Chairman/CEO and President.
In this role, he oversees an organization that has grown substantially since its creation. His public appearances often focus on supporting veterans and first responders, helping their families, and preserving the memory of those who died in service.
His leadership has also kept Stephen’s story at the center of the organization’s identity rather than allowing the foundation to become simply another general charitable organization.
Military Service
There is no reliable public evidence establishing that Frank himself served in the U.S. military. His connection to the military is primarily through his leadership of a foundation that supports service members, veterans, Gold Star families, and other heroes.
The distinction is important because Frank’s public biography is closely connected to military causes, but that does not mean he personally served in the armed forces.
The foundation’s work includes support for catastrophically injured veterans and families of service members who died in the line of duty.
What Is His Religion?
Religion has been an important part of Frank’s personal and family background. Reliable profiles identify him with the Catholic faith, and he has spoken publicly about attending the same Catholic church in Staten Island that he attended as a child.
His parents, George and Mae, were also deeply connected to Catholic and Franciscan traditions. Frank has explained that his parents’ example taught the family about service, sacrifice, faith, and doing good for others.
These beliefs have remained closely connected to the family’s charitable mission.
What Is His Net Worth?
There is no reliably verified public figure for Frank Siller’s personal net worth. Although many celebrity and biography websites may publish estimated figures, those numbers are not necessarily based on financial records or statements from Frank himself.
Because he is primarily known as a nonprofit leader rather than a celebrity whose personal finances are publicly reported, assigning a specific dollar amount would be speculative.
For an accurate article, it is safer to state that his exact net worth has not been publicly confirmed rather than publish an unsupported estimate.
A Legacy Built From Loss
The story behind the Tunnel to Towers Foundation is closely tied to the Siller family’s decision to respond to tragedy through service.
Frank has repeatedly described Stephen’s sacrifice as something the family could not allow to be forgotten. Instead of allowing grief to define the family’s future, the Siller siblings created an organization intended to help other families facing their own losses.
That philosophy continues to shape the foundation’s programs. Its work now extends to first responders, veterans, Gold Star families, and children of fallen heroes.
25th Anniversary of September 11
The year 2026 marks 25 years since the September 11 attacks, making it a particularly significant year for the Siller family and the foundation.
As part of the anniversary, Tunnel to Towers organized the Steel Across America tour, carrying a large piece of World Trade Center steel to communities across the country. The tour was designed to remember the people who died on September 11 and the heroes who responded that day.
On September 11, 2026, Frank and members of the Siller family retraced Stephen’s journey through the Brooklyn-Battery Tunnel. The event marked a deeply personal moment for the family and a reminder of the sacrifice that inspired the foundation.
Memoir and Personal Story
Frank’s story is also being shared through his memoir, Let Us Do Good, published in September 2026 by Broadside Books, an imprint of HarperCollins.
The memoir focuses on Stephen’s life and death, the Siller family’s faith and values, and the development of Tunnel to Towers over the years. It provides a more personal account of how the family transformed one of its greatest losses into a long-term mission of service.
