 Mario joined the National Guard and after 9-11, he volunteered to help with the recovery efforts at Ground Zero. Later, Mario and his wife had a daughter. Motivated by his 9-11 experience, he enlisted in the US Army. Sergeant Mario Nelson later deployed to Iraq. Just two months shy of coming home, he was killed in action at the age of 26. Thanks to the support of friends like you, the Tunnel to Towers Foundation delivered a mortgage-free home to Mario's wife and daughter.
