SGT Lee Ielpi, U.S. Army (1968-1970) SGT Ielpi has lived his life in honor of those he has lost - the multiple members of his reconnaissance unit in Vietnam and his son, Jonathan, who was killed in the 9/11 attacks at the World Trade Center. As the President of the Board of Directors for the September 11th Families' Association and co-founder of the 9/11 Tribute Center, he has worked tirelessly to educate people on the "good" that has come from such a tremendous tragedy. As we reach the 15th anniversary of one of the darkest days in American history, Lee wants to "let young people know that through the understanding of 9/11 they can learn the importance of service and contributing to their communities" and is spearheading a campaign to expand the mission of the 9/11 Tribute Center to do exactly that.
