DENVER - AARP estimates Americans lose $40 billion to investment scams each year. And many of the victims are seniors.

In one case, 39 investors lost more than $2 million dollars to one scammer. 7Everyday Hero Joe Pells is trying to keep you from getting ripped off.

Pells volunteers for the AARP Foundation, which operates Consumer Fraud Prevention Centers. They are call centers designed to make critical phone calls to help consumers.

"We hope to make 2,000 to 2,500 calls to let folks know about the dangers of financial fraud," said Bob Toye, an AARP call center manager.

"I have spoken to people, intelligent people, who've been scammed, and they share their experience with me," said Pells.

Pells gives his time to make about 90 calls a week, helping upwards of 4,500 Colorado seniors over the years.

"Joe is the best. He has been here every week for three years," said Toye.

"I enjoy doing it," said Pells.

Volunteers say when it comes to scams, there is really no end to them.

"We have made calls about every fraud that you can imagine. Well, I shouldn't say that because there will be one tomorrow that we haven't imagined," said Toye.

"Even when you are onto scams, you don't know them all. It's amazing how people can be fooled," said Pells.

But fewer people fall victim thanks to the AARP Foundation and volunteers like Joe Pells.
