Martinez-Fonts is the former vice-chairman of the J.P. Morgan Private Bank, earlier serving as CEO of J. P. Morgan Florida, Private Banking, and J.P. Morgan Latin America. As CEO he was responsible for overseeing the firm’s wealth management business in Florida and Latin America, both large growth markets for the firm. He was also a member of the Private Bank Executive Committee, the global decision-making group for day-to-day strategic and operating matters.
Previously, he worked as a commodities trader covering Asia and Latin America for Czarnikow Rionda Co. and lived in both London and Hong Kong, where he became fluent in Mandarin and Cantonese.
Since his retirement in 2015, Martinez-Fonts splits his time between his home in Florida and Los Angeles, where he is a private investor and where he has also had the privilege of volunteering with young people who are setting up businesses but do not have access to seasoned business advice or capital. His greatest joy comes from his work with homeless young people in recovery.
His youngest son, Joseph, graduated from Notre Dame in 2007 and received his masters in education from the university in 2009, making Martinez-Fonts the proud father of a "double domer."
Martinez-Fonts was born in Havana, Cuba and raised on New York's Long Island. He holds a BS in foreign service from Georgetown University.
