Haiti is still in desperate need of international assistance and all of the charities we talked with said they would eventually use all of the money donated for Haiti.
"All funds raised will be used for Haiti relief and rebuilding efforts, which will take years, not months," the spokeswoman for World Vision told us.
So what should Americans do? Give, says Berger. But give wisely.
"The heart of the American people, over and over again, it's just amazing," Berger said. "Use your head as well as your heart. Do a little due-diligence and think through the best way to give."
Despite the fact that some organizations could not provide ABC News with details of their work, most American charities are more transparent about their giving than ever before. In many cases, the Internet makes it easy for donors to track where there money is going.
ABC News' Daniel Arnall, Mary Kate Burke and Susan Kriskey contributed to this report.
