Raffie, I do suggest you read book "The Difference a D.O. Makes" that was handed out during the interview. It'll give you insight about what a D.O. does and where the stigma comes from (gives you a history of the AMA having beef with AOA and why, WWI issues, etc).
I worked as a scribe in the E.R. for over two years and many of the physicians were D.O.s. Interestingly, most of the positive patient feedbacks from the callback logs were addressed to the D.O. docs. D.O.s are more patient-oriented vs disease-oriented so they focus more on pro-actively maintaining good health (FM) than waiting for symptoms to arise for treatment (specialization). I'd still have a difficult choice to choose between an MD and DO school, tbqh.
