Hi Mike,
Congratulations on your first interview. I just got mine for DMU as well, except it is on Nov. 15. I'm going to try to change it to the 16th. My situation is similar to yours, in that I applied to allopathic schools last year and discoverd how much more I relate to osteopthic principles in the midst of all of it. I'm applying solely to DO schools now. How and when did you start familiarizing yourself with OM? I'm really excited about it. What do you plan on telling adcoms if they ask you about your previous applications to allopathic school only? Do you know anything about DMU and the interview structure? best of luck and maybe I'll see you at DMU.
