I volunteer at Kaiser Riverside outpatient pharmacy, in California. And it was relatively easy to get. But I know a lot of Kaiser Hospitals do not like volunteers in their pharmacy department so if you want to volunteer at Kaiser, find their volunteer office and see if they allow volunteers in the pharmacy. My interviewer at USC was actually impressed a little that I was actually a volunteer at Kaiser, but don't know how far that will me (still waiting to hear back from them). Also, at least for my Kaiser, I heard it's easier to get a job at Kaiser like sales assistant position, if you've done volunteer work at that pharmacy. So I definitely would recommend Kaiser. If not, any volunteer work somewhere is better than no work at all, right?
