Heroic Run to Honor 9/11 Firefighter Stephen Siller's Last Journey

This video tells the poignant story of Frank Siller and his journey to honor his brother, Stephen Siller, a firefighter who sacrificed his life during the 9/11 attacks. Frank established the Tunnel to Towers Foundation in tribute to Stephen's heroic actions, which organizes an annual run following the route Stephen took to the Twin Towers. The event has grown massively, drawing tens of thousands of participants who aim to keep the memory of that day alive. The foundation has also expanded its remit, providing support to families of fallen first responders and veterans through various initiatives, including mortgage-free homes.
