Based on the websites for these programs that have them, the most recent graduates within the past several years to go to IR have gone to top places, many in competitive locations, like Miami Vascular and Dotter (Kaiser), Mount Sinai (SBC and Cedars), U Colorado (Cedars), and U Washington (SCVMC). And yet, because many of them didn't go to Stanford or UCLA, you assume that they must have wanted to stay in California but weren't competitive enough to do so? I can understand the reasoning behind how you came to your assumption, but IR is a considerably different beast from the other specialties in that applicants tend to be more competitive and inclined to go to the best training program nationwide due to the variable nature of IR training, whereas for most of the other subspecialties you can learn pretty much most of it at most fellowships, and location becomes a bigger factor. As much as people may like to think that California is the best in everything, the IR programs considered to be at the very top in the nation are not in California.
