Ford, a former police officer, lost his home in Katrina. This is his third volunteer trip with Parness' group.
"(After the storm), I had a lot of people help me. The Sadlers needed our help, and so here we are, " Ford said. "Being here gives the Sadlers the confidence to know that they're not alone in this adventure."
For Parness, bringing people together is the most important part of his work.
"We want to lift up spirits and remember not just the tragedy of (9/11), but also the humanity of 9/12.
"We tell people it's never about the buildings. It's always about the people. At the end of the day, it's about giving them hope."
