I have volunteered a few times at United Cerebral Palsy this semester, and have taken other students with me (I'm a student at USC). Each time we've come the staff have been very warm and professional, and done everything to make us feel as comfortable as possible while interacting with their clients. Though we've only been for two hours each time, the staff truly seem to care about the clients in their interactions with them; the setup of their day center also allows new volunteers to come in and feel comfortable helping out.
