While Americans across the nation are reflecting on the lives lost on Sept. 11, 2001, thousands of volunteers in the city spent the 22nd anniversary of thw terror attacks honoring the memory of the fallen by giving back.

“Tommy Dowd the rock, Jimmy Mack, Joey Kellen and many more,” said Carmel McDonald, who works at the law firm Morgan Lewis.

McDonald said she decided to volunteer at the September 11 National Day of Service and Remembrance at the Intrepid Sea, Air and Space Museum on Monday to honor friends she lost on 9/11 and those who died of 9/11-related illness.

The loss of one friend hits home hard for her.

“My friend Pete Chiodo who just recently passed away as a result of 9/11,” McDonald said. “He was a firefighter in Brooklyn. Thinking of his family, his daughters and everybody today.

”Chiodo, who died last November after a long battle with a World Trade Center-related illness, served 25 years at Engine 226, including during the 9/11 attacks.

Volunteers worked in shifts on Monday and will do so again on Tuesday, packaging 1.5 million meals for families and people in need.

“The team comes together as a team. They’re packing as a team and they’re having fun, but they feel really good about what they’re giving back to the community,” said Andrea Principe, the northeast consumer banking divisional director at JPMorgan Chase & Co.

The September 11 National Day of Service and Remembrance representatives said national charity U.S. Hunger provides the food, which is then delivered to City Harvest and the Food Bank For New York City.

“We attempted to create something in this country where people came together in unity and focused on our common humanity the way people did after 9/11,” said 9/11 Day co-founder Jay Winuk.

What started out as a way to honor his brother, Glenn Winuk, who died trying to rescue people on 9/11, became an event that has grown tremendously since its first days in 2002.

“So when the planes hit, Glenn helped to evacuate their law offices and then headed on foot into to the South Tower to save lives and Glenn perished when the South Tower collapsed,” Jay Winuk said.

Maria Fufuzza of the law firm Holland and Knight said she and Glenn Winuk began working at Holland at Knight around the same years before he became a partner at the firm, located close to the Twin Towers at the time.

When Winuk wasn’t at Holland and Knight, he volunteered his time as a firefighter and EMT in his hometown of Jericho on Long Island, where he spent 20 years working as a volunteer firefighter, EMT, lieutenant and fire commissioner.

Last week, retired FDNY firefighter Peter Chiodo’s name was among 43 additional names that were added to a list of members who died of World Trade Center-related illnesses on the World Trade Center Memorial Wall.

Just over 340 firefighters have died as a result of 9/11-related illnesses, on top of the 343 firefighters who died on 9/11.
