Barry Greenstein has been called the “Robin Hood of Poker” for good reason: this lean, quiet, unassuming character donates 100% of his tournament earnings to charity. Most of it goes to Children Incorporated, an organization which sponsors some 15,000 children in 21 countries. Not merely a small act of kindness, for someone whose winnings are now in excess of $3.9 million.
His charitable nature has won Greenstein invitations to quite a few tournaments. He played in more than 40 events in 2003 alone. Among his many accomplishments were winning Larry Flynt’s $1 million one-table stud event at Hustler Casino, and bagging $100,815 in the $500 No-Limit Hold’em event at Commerce Casino’s California State Poker Championship. Never ceasing to learn new things, Barry Greenstein taught his long-time girlfriend Mimi Tran how to play poker in exchange for her teaching him how to speak Vietnamese. The two have exchanged light-hearted banter in public, with both claiming to be the better teacher.
“Robin Hood” came into the world on December 30, 1954. He was born and raised in Chicago. He learned about poker at a young age, as his father was a known poker player while he was serving in the Army, and he played with his mother many times besides. At age 13, Barry could make $30 to $50 a night playing poker in home games. At 20, he was a professional. But he had other talents besides poker, and these included computer skills – he had developed his own software before the age of 15.
The precocious Greenstein never neglected his education. After graduating from Bogan High School, he got his bachelors degree in computer science and doctorate in mathematics from the University of Illinois. Facing divorce later in his life, he was told by his lawyer that he needed to get a respectable job for the sake of his children. So he worked for Symantec until he retired at age 36. He then returned to playing poker full-time, partly to help his wife and daughter financially through a job that doesn’t constrain his earning power.
It is no secret Greenstein loves children, especially his own six children and step-children. He is in the process of writing a poker book, which he says he will dedicate to children, especially children of professional gamblers, who may have had to suffer missing their parents during important times in their lives. Barry Greenstein is currently residing in Ranchos Palos Verdes, California.
A Cash Game Monster First, Tournament Player Second
To understand Barry Greenstein, you have to understand what the poker world often underestimates about him: his cash game record is arguably more impressive than his tournament résumé.
As he is not an attention seeker, casual poker fans have not gotten to know much about Barry except that he gives away his tournament paychecks. In recent years, however, he has become more and more popular for his cash game skills as a result of his appearances on the television show High Stakes Poker.
The scale of his cash game success is staggering. At the 2003 WSOP, most people think that Chris Moneymaker was the big winner, cashing in for a little over $2 million at the main event. According to Greenstein, though, he won over $5 million playing cash that month in Vegas.He came to Las Vegas in around 2003–2004 at the invitation of his friend Sailor Roberts to play at Bobby’s Room — the world’s most famous super high-stakes cash game room at the Bellagio. There, he competed regularly against the likes of Doyle Brunson, Phil Ivey, and Chau Giang.
For poker enthusiasts who study bankroll management, there’s a lesson here: Greenstein could afford to donate tournament earnings precisely because he never relied on them. His real edge was in the cash games — where he sat for longer, played deeper, and exploited skill edges that tournament variance obscures.
The Making of a Mathematical Mind
Barry Greenstein was born on December 30, 1954, in Chicago, Illinois. His path to the poker table was shaped as much by intellect as by environment. His father played poker while serving in the Army, and the young Barry was exposed to card games early — picking up gin rummy, hearts, and eventually poker with a natural ease that signalled something more than casual talent.
By 13 he was already profitable. By 20, he was a professional. But Greenstein was never content to be just a poker player. After graduating from Bogan High School, he earned a bachelor’s degree in computer science from the University of Illinois at Urbana-Champaign, and studied for a PhD in mathematics without ever defending his completed dissertation.
He skipped a grade in high school, graduated from college in the 70s with a computer science degree after just three years, and spent the next ten years working on a math PhD while building his poker bankroll.That combination — deep mathematical thinking layered over genuine street-level poker experience — is a rare pairing, and it shows in the precision of his game.
He single-handedly wrote an award-winning word processing software at Symantec. He was so good at his job that Bill Gates offered to double his salary, to which Greenstein reportedly replied: “I don’t work for money. I work for my projects.” He eventually left Symantec and returned to poker full-time — a decision that, by any financial measure, worked out rather well.
Poker Hall of Fame and a Legacy That Holds Up
Inducted into the Poker Hall of Fame in 2011, Greenstein holds 3 WSOP bracelets, 2 WPT titles, and over $8 million in live tournament winnings.His estimated net worth sits around $10 million, accumulated through tournament winnings, high-stakes cash games, sponsorships, and his book.
He also played online at PokerStars under the alias “barryg1” and was a member of the cardroom’s Team PokerStars. In the 2024 WSOP, Greenstein participated in seven events, with his most notable performance coming in the $3,000 Limit H.O.R.S.E., showing that while the intensity of his participation may have changed, his competitive spirit remains intact.
What makes Greenstein genuinely unusual in the poker landscape is how little the game seems to define him in the way it defines so many others. He once said: “I never loved poker. I did it because I could make money easier than other jobs.” From a man who has donated millions of those earnings to charity and used his platform to shine a light on children in need, that’s perhaps the most interesting tell of all.
