Tunnel to Towers Founder Frank Siller to Publish Memoir, Let Us Do Good, on September 1
Published by Broadside Books, an imprint of HarperCollins, on the 25th-anniversary year of September 11, the memoir tells the story behind America’s largest organization serving veterans, first responders, and their families
STATEN ISLAND, N.Y. [July 20, 2026] — The Tunnel to Towers Foundation announced today that its Chairman and CEO, Frank Siller, will publish his memoir, Let Us Do Good, on September 1, 2026, from Broadside Books, an imprint of HarperCollins.
The book takes its title from the words the Siller family has lived by for generations. On the morning of September 11, 2001, Frank’s younger brother Stephen, an off-duty FDNY firefighter, strapped on his gear and ran through the Brooklyn Battery Tunnel toward the Twin Towers, where he gave his life saving others. In the years that followed, a grieving family turned a promise into a movement — and “Let us do good,” the phrase passed down from their parents, Mae and George Siller, became its guiding mission.
In Let Us Do Good, Frank Siller tells that story in full: the brother he lost, the faith and family that carried him through, and how the Tunnel to Towers Foundation grew into the nation’s largest organization supporting catastrophically injured veterans and first responders, Gold Star families, and the families of fallen first responders. It is a personal memoir, a portrait of American generosity, and a blueprint for turning loss into purpose.
“For 25 years, the American people have stood with us as we have worked to do good in my brother Stephen’s name,” said Frank Siller. “This is the story of how our family’s greatest loss became a promise we intend to keep — to the families of our fallen heroes and to the veterans who have given so much. Our parents always instilled in us the words and teachings of St. Francis, ‘Let us do good.’ I wrote this book so that these words, and Stephen’s sacrifice, will inspire others to do the same.”
*Advance praise for Let Us Do Good:*
“A pilgrimage yearning to be told. Frank details our family’s journey rooted in deep faith, love, and charity. Jarred by tragic events yet lifted by humanity in our darkest moments, this book teaches us how grief not only sustains us but can fuel our vision, promise, and purpose — leading us to shelter one another. And yes, you can judge this book by its cover.”
— Sally Siller, Widow of Stephen Siller
“Long before most people knew the name Tunnel to Towers, Frank Siller was already building something extraordinary. I was proud to be there early — to lend my voice to their PSAs and do whatever small part I could — because Frank’s commitment to America’s heroes was impossible to say no to. This book is the story behind the mission, and it’s one every American should read.”
— Mark Wahlberg, Actor / Producer
Publication coincides with the 25th anniversary of September 11 and the Foundation’s Steel Across America tour, a national journey carrying steel from the World Trade Center to communities across the country. Frank Siller will mark the launch with national media appearances and a series of events throughout September.
Let Us Do Good goes on sale September 1, 2026, and is available for pre-order now wherever books are sold.
