I would specify whether you mean UCLA/Olive View or UCLA/LAC-Harbor. Two different animals. I rotated at Olive View but checked out both USC and Harbor while I was out there. I would vote USC as well. It was interesting to say the least. I think that you would have to be the kind of student that likes to learn by doing and lots of trauma. If you like the sit down and learn about cases kind of thing, I would probably vote Harbor. Both have tons of spanish-speaking folks. UCLA-Olive View has great faculty and great teaching (but wouldn't do it for a LOR because you spend 1.5 weeks at each of the two sites and don't work with any one attending much). I don't know anything about UCI.
