Thanks, npdoc.
I got a 23S, too and I'm a bit worried about it.  My undergrad GPA (UCLA) was about a 3.2, but I also have a ton of EC's and solid clinical experience.  I'm still studying for the August MCAT (and, I must say, just loving it!). 
I'm a practicing podiatrist (3 years out), did my residency at Los Angeles County/USC (very intense) and finished podiatry school with a 3.53.  Other than that, I have an interesting, varied work history, volunteer experience, etc., etc..  I have had a tremendous amount of relevant clinical experience and I'm hoping that this will be my golden ticket.
I did apply to other So Cal MD schools, but don't think I'll get in despite my DPM degree.  I want to go into primary care, anyway, so I think I'd be better off at a DO school.
I do have a question for you.  When they asked you about your interest and knowledge about osteopathic medicine, what did you tell them?  I visited the campus twice (once this year and once 10 years ago) and have read a lot about the profession (but all on-line).  I also worked with a DO ER doc at L.A. County when I was a resident and got some more info.  I kind of want to know what I can say or what I can read other than the typical stuff they hear.
Thanks again.
