Scott Greenberg is leaving CAA to become a manager and partner at LBI Entertainment. He is making the move amicably from agent to manager and will join LBI principal Rick Yorn, a close friend and mentor since they were fraternity brothers at the University of Maryland. Greenberg, who began working in the CAA mailroom 29 years ago, will be bringing a major infusion of A-list directors. They are still working out the details, but the clients who’ll be managed by Greenberg are expected to continue to be agented by CAA.
