Hedge fund manager David Einhorn, the founder of Greenlight Capital, is on Twitter @davidein and he’s been live Tweeting throughout the World Series of Poker tournament.
Einhorn, who now has more than 2,600 followers (he had just over 1,200 yesterday), only follows one person and his name is Daniel Roitman @droitman.
Roitman is the Chief Operating Officer at Greenlight and he’s been working at Einhorn’s hedge fund since 2003, according to his bio on Bloomberg BusinessWeek. He is also Einhorn’s fraternity brother in the Sigma Alpha Epsilon fraternity.
Prior to Greenlight, Roitman worked at Goldman Sachs where he joined the bank in 1996 as a technical architect developing the firm’s risk management systems. He moved up the ranks to a vice president in 1998. In 2000, he moved to Goldman’s technology strategy group and later joined the equities division business development group in 2002.
Roitman began his career as a consultant at Andersen Consulting, which later became Accenture.
He graduated with a degree in electrical engineering from Cornell University. He finished his bachelor’s in just three and a half years, so he decided to go ahead an get his master’s in electrical engineering from Cornell, too, according to a profile on Cornell’s site.
He also has his MBA in finance from NYU Stern.
Sadly, his Twitter account is private.
