Sima Birach, Jr. taps Castleberry for “Twin Star”


Sima Birach, Jr. tells RBR Red Zebra Broadcasting’s (Redskins Radio) Vice President of Operations, Tod Castleberry, has resigned his position to be Chief Operating Officer of Twin Star, a new emerging media startup from Sima (he’s the CEO) that incorporates radio and TV properties with a major ad agency component/division. 

Twin Star CMO Lisa Wynne tells RBR it’s a completely separate company from Birach Broadcasting, but is still rooted in traditional media—TV, radio. More details will be given in a few weeks, but we can say that Sima has hired a few strong execs for this new venture.
Tod’s last day at Red Zebra will be 12/28.
