Seif was born in Cairo, Egypt before moving with his family at the age of two, to Southern California. He received a bachelor’s degree in Economics from UCLA and a juris doctorate from Loyola Law School in Los Angeles.
In 2001, Seif quit practicing law to play poker full-time.
Seif's first major cash was when he finished fourth in the second ever World Poker Tour (WPT) event in August 2002. In May 2003, Seif had his first money finish in the World Series of Poker (WSOP) in the $3,000 no limit Texas hold'em event, where he finished in 9th place. That final table included Phil Hellmuth, Jr., Daniel Negreanu, and Erik Seidel among others.
Seif is best known for being the only player to win two WSOP bracelets in back-to-back events in 2005 in the $1,500 limit hold'em shootout and the $1,500 no limit hold'em events. He bested a field of 2,013 players to win his second bracelet. At that final table, he defeated Minh Nguyen, Greg Raymer, Dave Ulliott, and Bill Gazes among others.
Later in 2005, Seif won the US Poker Championship in seven-card stud at the Taj Majal in Atlantic City, New Jersey. He also made the final table at the World Championship of Online Poker that same year.
Seif was a color commentator for the Professional Poker Tour television series which aired on the Travel Channel starting in July 2006 and ended in late 2007. He has been a spokesperson for Absolute Poker since 2004.
In 2007, Seif purchased a US Poker Bowl franchise named the Detroit Absolute Nuts, who went on to win the first ever US Poker Bowl Conference Championship.
