If the phone just rings and rings at UTA today here’s the reason: the agency’s employees are out of the office participating in the second annual Project Impact, a weeklong event organized by the UTA Foundation devoted to philanthropy. The initiative culminates today in an all-company volunteer day, in which several hundred agents, executives, assistants and staff are spread out across 15 sites throughout LA and NY. The week kicked off with a Q&A session with DreamWorks Animation CEO Jeffrey Katzenberg and included UTA’s annual summer fundraiser Tuesday for its arts and literacy programs.
