Brazilian billionaire and businessman Edson de Godoy Bueno has an estimated net worth of $2.3 billion as of April 2016 according to Forbes. He is best known as the ex-husband of fellow billionaire Dulce de Godoy Bueno. Most of Edson Bueno's massive net worth is derived from Amil, a health plan company. Along with his wife Dulce, Edson founded Amil in 1972.

While working in a clinic, Edson de Godoy Bueno attended Universidade Federal do Rio de Janeiro. After graduation in 1971, he bought the struggling clinic. In the last five years, Edson Bueno has purchased more than 15 firms which made Amil as the largest health care company in Brazil.

Towards the end of 2012, it was reported that United Health Group (UHG), a giant health insurance in the U.S., purchased Amil's 90% stake for $4.9 billion. UHG took 60% of Amil's stake from Edson and Dulce Bueno while the remaining 30% was taken from the public shareholders of the company. Today, the couple owns 10% of Amil and Edson still serves as the company's Chief Executive. Furthermore, the couple owns stakes in Dasa which is considered as the Latin America's largest chain of laboratories. They also hold interests in Totalcare which is a private holding company that specializes in managing investments in many hospitals based in Sao Paulo and Rio de Janeiro.
