Matrix Applications is proud to have joined the 24th Annual Tunnels to Towers 5k Walk and Run in New York City on September 28, 2025 alongside South Street Securities and AmeriVet Securities. In partnership with David Harris Collection, our Tunnels to Towers Team joined over 30,000 participants, raising over $1,400 and honoring the heroes on September 11, 2001.
The Tunnels to Towers event honors fallen FDNY hero Stephan Siller for his race through the Brooklyn-Battery Tunnel to the World Trade Center towers on the day of the attacks. Participants retrace his steps in homage to heroes and the lives lost.
Since 9/11, Tunnels to Towers has been helping America’s first respondents and veterans by providing mortgage-free homes to Gold Star and fallen first responder families, in addition to building specially-adapted smart homes for catastrophically injured veterans and first responders. They are also committed to eradicating veteran homelessness and helping America to Never Forget September 11, 2001.
"Walking with many other people to honor the sacrifices made by first responders during the 9/11 attacks was an incredible opportunity and I am proud to have participated in such an event. It is important that we never forget the date and the heroes of America." - Henry Outeiral, Matrix Applications
