He studied for a PhD in mathematics without ever defending his completed dissertation. According to his book, Ace on the River, Greenstein was doing well playing poker, but figured a more conventional job would improve his chances of adopting his stepchildren, so he went to work for the new startup company Symantec, where he worked on their first product Q&A. He left the company in 1991 at age 36. Greenstein has two children and four stepchildren, and he resides in Rancho Palos Verdes, California.
