Stepson of the great Barry “Ace on the River” Greenstein, Joe Sebok, signs with online poker room Ultimate Bet. Sebok is joining Ultimate Bet as a media and operations consultant while he also helps shape the UB poker room into a poker site made directly for its players. Joe Sebok is also a website CEO and a radio host as now he takes on the role as a UB pro. Sebok has worked with or at least he has promoted Poker Road in the past before signing with UB. If he is anything like his stepfather, UB found a solid poker pro with this signing.
