The Tunnel to Towers Foundation honors the sacrifice of firefighter Stephen Siller who laid down his life to save others on September 11, 2001. Tunnel to Towers also honors our military and first responders who continue to make the supreme sacrifice of life and limb for our country. The Tunnel to Towers Foundation builds mortgage-free smart homes for our most catastrophically injured veterans. Each home is designed to address the unique needs of each individual. Smart homes host a myriad of features such as automated doors and lighting, wider halls and doorways, special showers to accommodate wheelchairs, automatic door openers, cabinets, counters and stove tops that can be raised and lowered, back-up generators and central heating and air-conditioning systems that can be controlled by tablets. These homes help our most severely injured veterans to reclaim their day-to-day independence.
