Frank Siller, the founder and CEO of the Tunnel to Towers Foundation, has dedicated his life's work to honoring his brother, Stephen Siller, who perished in the September 11, 2001, terrorist attacks.

Stephen Siller, a firefighter with the New York City Fire Department, was returning from his shift when he heard about the attacks. He turned his truck around and drove toward the World Trade Center, parking it and running through the Tunnel to Towers, ultimately entering the North Tower to help evacuate people. He was among the nearly 3,000 victims who lost their lives that day.

Frank Siller has spoken about the profound impact his brother's sacrifice had on him and how it inspired the creation of the Tunnel to Towers Foundation. The organization's mission is to honor the sacrifice of first responders and military service members who lost their lives on 9/11, and to continue their legacy by supporting wounded veterans and their families. The foundation has grown significantly since its inception, becoming a major force in charitable giving.

The foundation has expanded its reach beyond memorializing 9/11 victims. It now focuses on providing mortgage-free homes to Gold Star families and the nation's catastrophically injured veterans, a program that has helped hundreds of families achieve financial security and stability. This initiative directly addresses the ongoing needs of those who have made profound sacrifices for the country.

Frank Siller often recounts the personal pain and loss he experienced, emphasizing that his brother's final act of heroism motivates his continued efforts. He has stated that his brother's love and commitment to service are the driving forces behind the foundation's success and its ability to impact so many lives. The foundation's work ensures that Stephen Siller's memory, and the sacrifices of all first responders, are never forgotten.

Through various fundraising events, including its signature Tunnel to Towers 5K Run & Walk, the foundation raises millions of dollars annually. These events bring communities together to remember 9/11 and support the foundation's ongoing programs. The scale of these events highlights the widespread public support for the foundation's mission and its connection to the events of 9/11.

Experts in the non-profit sector note the effectiveness of the Tunnel to Towers Foundation's model, which combines direct support for beneficiaries with a powerful narrative of sacrifice and remembrance. The tangible impact of providing homes to families is a key factor in its public appeal and fundraising success.

The organization's commitment to its mission remains steadfast, with Frank Siller at the helm, ensuring that the legacy of his brother and the heroes of 9/11 continues to inspire service and provide critical support to those in need.
