"Right now we're at a level where we're giving out half tuition. It's a pretty big deal," Neil Peraza said.
The family also established a scholarship for students at Norwich High School in New York.
"The issue here is to honor Rob," his father said. "I'm just an instrument for celebrating his life."
In August 2001, Peraza's son had written a four-page letter to his family, "saying how wonderful his life was," Robert Peraza told ABCNews.com.
His son was planning on getting engaged, and enjoying his job as a bond trader at Cantor Fitzgerald where 657 others also died on 9/11.
Rob Peraza had been scheduled to run the New York City Marathon in 2001, and assigned number 1461. He never got to run that race, but in the 10 years since 9/11 a relative has run the race using his number. This year it will be his sister, Joan.
Had Rob seen the picture of his father taken Sunday, Neil said, "I'm sure Rob would be really sad because we're all sad. But I think Rob would be really proud that as a family we're celebrating his life every day."
The Perazas revisited the 9/11 memorial today when it opened to the public, and paused once more in front of the North Pool, to pay their respects to all 2,753 people who died after two hijacked planes crashed into the World Trade Center.
"After 9/11 my wife and I realized that life continues and you have two children you have to live for," Robert Peraza said. "Rob was the kind of young man who would have been very upset if my wife and I wilted."
