Jamie Dimon

James Dimon (born March 13, 1956) is an American billionaire banker and businessman.

Dimon began his career as a management consultant at Boston Consulting Group from 1979 to 1982.

He then joined American Express, with an early mentor, Sandy Weill, working there from 1982 to 1985.

He graduated in 1982, earning an MBA as a Baker Scholar.

After graduation from Harvard Business School, Sandy Weill convinced him to turn down offers from Goldman Sachs, Morgan Stanley, and Lehman Brothers to join him as an assistant at American Express.

Although Weill could not offer the same amount of money as the investment banks, he promised Dimon that he would have "fun".

Dimon's father, Theodore Dimon, was an executive vice president at American Express.

Sandy Weill left American Express in 1985 and Dimon followed him.

The two then took over Commercial Credit, a consumer finance company, from Control Data.

Age 30, Dimon was the chief financial officer, helping to turn the company around.

Dimon was appointed chief financial officer (CFO) of Commercial Credit in 1986, aged 30, later becoming the firm's president.

He was the chief operating officer (COO) of both insurer Travelers and brokerage firm Smith Barney from 1990 to 1998, becoming the president of Citigroup in 1998.

It was rumored at the time that he and Weill argued in 1997 over Dimon's not promoting Weill's daughter, Jessica M. Bibliowicz, although that happened over a year before Dimon's departure.

At least one other account cites a request by Dimon to be treated as an equal as the real reason.

Through a series of mergers and acquisitions, in 1998 Dimon and Weill were able to form a large financial services conglomerate, Citigroup.

Dimon left Citigroup in November 1998, after being asked to resign by Weill during a weekend executive retreat.

In 2000, he was appointed the CEO of Bank One, overseeing operations until its merger with JPMorgan Chase in 2004.

Dimon then became the COO of JPMorgan Chase, assuming the role of CEO two years later.

In March 2000, Dimon became CEO of Bank One, the nation's fifth largest bank.

When JPMorgan Chase merged with Bank One in July 2004, Dimon became president and chief operating officer of the combined company.

On December 31, 2005, he was named CEO of JPMorgan Chase and on December 31, 2006, he was named chairman and President.

He has been the chairman and chief executive officer (CEO) of JPMorgan Chase since 2006.

Dimon was included in Time magazine's 2006, 2008, 2009, and 2011 lists of the world's 100 most influential people.

, Forbes estimated his net worth at $2 billion.

Jamie Dimon was born in New York City.

He is one of three sons of Theodore and Themis (née Kalos) Dimon, who had Greek ancestry.

His paternal grandfather was a Greek immigrant who worked as a banker in İzmir and Athens, and changed the family name from Papademetriou to Dimon.

Dimon has an older brother, Peter, and a fraternal twin brother, Ted.

Both his father and grandfather were stockbrokers at Shearson.

He attended the Browning School, and majored in psychology and economics at Tufts University, where he graduated summa cum laude.

At Tufts, Dimon wrote an essay on Shearson's mergers; his mother sent the paper to Sandy Weill, who hired Dimon to work at Shearson during one summer break, doing budgets.

After graduating, he worked in management consulting at Boston Consulting Group for two years before enrolling at Harvard Business School.

During the summer at Harvard, he worked at Goldman Sachs.

In March 2008 he was a Class A board member of the Federal Reserve Bank of New York.

Under Dimon's leadership, with the acquisitions during his tenure, JPMorgan Chase has become the leading U.S. bank in domestic assets under management, market capitalization value, and publicly traded stock value.

In 2009, Dimon was considered one of "The TopGun CEOs" by Brendan Wood International, an advisory agency.

He was on the board of directors of the Federal Reserve Bank of New York during the late 2010s.

Since then, Dimon has been a board member of the Business Roundtable, the Bank Policy Institute, and Harvard Business School.

On September 26, 2011, Dimon was involved in a high-profile heated exchange with Mark Carney, the governor of the Bank of Canada, in which Dimon said provisions of the Basel III international financial regulations discriminate against U.S. banks and are "anti-American".

On May 10, 2012, JPMorgan Chase initiated an emergency conference call to report a loss of at least $2 billion in trades that Dimon said were "designed to hedge the bank's overall credit risks".
