Fekkak Mamdouh was scheduled for work on the 107th floor of the WTC’s North Tower on the day of the September 11, 2001 attacks. A former waiter at Windows on the World restaurant, he lost 73 friends and colleagues when the towers fell. After the dust settled, Mamdouh co-founded an organization to help the newly displaced workers — many of them undocumented immigrants — navigate their way to new jobs in the restaurant industry. This year, that organization has opened branches nationwide, and expanded far beyond its immigrant base.
