For the fiscal year ending September 2013, the Executive Director of the Wounded Warrior Project, Steven Nardizzi, received a total compensation of $375,000.
Unfortunately, the six veterans-related charitable organizations mentioned above don't receive very high marks for efficiency (as determined by Charity Navigator, the BBB, or Form 990 information):
American Legion: 55%
Veterans of Foreign Wars: 84%
Disabled American Veterans: 77%
Military Order of Purple Heart Service Foundation: 35%
Vietnam Veterans of America: 25%
Wounded Warrior Project: 58%
Harvests credit card numbers and skims small amounts of money off of them hoping people don't notice? Ended up having to get a new card due to an unauthorized transaction by this name. Further searching shows they're a shady "charity" that compensates "employees" 6 figures.
