Today Mangano is CEO of Ingenious Designs, a multimillion-dollar company she built while becoming a household name on the Home Shopping Network.
The woman who once struggled in a small ranch home, is living on Long Island's North Shore in a 42,000-square-foot mansion with 14 bedrooms and 13 bathrooms. But you won't find her sitting by the pool very often. Her kids say she's just too busy, always thinking up new products.
"We were on vacation in the Hamptons and she sees this person come out, holding pies and these two pies, you can't get in the car," her son Bobby daughter Christie recalled. "He's trying to get his keys and she came up with a bakery box that she launched a year later.
Among Mangano's 100 employees is Tony Miranne, her ex-husband, who is executive vice president of sales.
"Joy truly possesses the inner drive to achieve what she wants to achieve," Miranne said. "She's 24/7, eat, sleeps and drinks achieving; It's a great success story."
Mangano tells 20/20 "Obviously, the product is king. Behind that, the determination and the ability and the knowledge to know where to take risks, where not to, where to be smart and what to give up and what not to give up.
And Mangano encourages others to follow through on their ideas too. "If it's anywhere near a realistic goal, I say, 'Go for it' because, look at me! I mean, in a million years, I never thought that I would be in this place, in this situation 20 years ago. All because of a mop that started it. It truly is the American dream.
