0

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.
