I could care less if one is a DO or an MD. A doctor is a doctor is a doctor. It doesnt matter which route you choose, the qualifications are the same. However, I think that DOs do themselves a great disservice when they defend their profession. I was interested in going the DO route. However, I had experiences with DOs that turned me off.
First, I shadowed one at a local emergency room. He knew I was a pre-med. He knew I had only taken basic biology. However, he proceeded to drill me about detailed anatomy and medical practice (specific reflex arcs, suture technique, etc) in front of every patient he treated. I never knew the answers and he would proceed to make a fool out of myself. I later spoke with many of the nurses, and they said that he had a habit of doing that. He was the only DO on the staff and continually had to prove himself.
Second, I spoke with an admissions dean from a local osteopathic school. I was asking questions about the process and what I could do to improve my application. He half assedly answered my questions, and then continued to defend osteopathic medicine for half an hour. He went on and on about how it was okay to be a DO. I never asked anything that would require that discussion.
In summary, I became very turned off. True, I can't generalize about DOs as a whole, but as an applicant, you have to make decisions based upon your experience. If you believe you will have to defend yourself throughout your career, why bother? I hope most of you will decide to prove yourself through your actions and not your words. Perform well and the respect will be there. Of course you will meet some jack*ss MDs, but screw 'um. I feel that the best way to promote the profession is through hard work. Just my $.02.
