ToggleBarry Greenstein: Personal Life
Barry Greenstein was born on December 30, 1954, in Chicago, Illinois. Raised in a family that valued education and intellect, he learned to play poker from his father at an early age. His natural aptitude for mathematics and logic quickly became apparent, and by the time he was a teenager, he was already playing poker for money—though his early games were often casual and family-based.
He went on to study mathematics and computer science at the University of Illinois, eventually earning a graduate degree. Before becoming a professional poker player, Barry worked as a software developer at Symantec, where he contributed to the development of the Norton Utilities software suite.
He has three children and is known for keeping his personal and family life relatively private. One of his stepsons is professional poker player Joe Sebok, with whom Barry has collaborated in the poker world.

Instead, it was a passion for the game, a desire for autonomy, and a belief in poker’s intellectual depth that led him to the tables.
