SDN Members don't see this ad. (About Ads) I'm only applying to DO schools this year. Why many MDs (students, residents, attendings) first reject CaribbeanMD > DO, but then all of a sudden start looking down upon to DO schools in any thread/conversation when commenting about competitive ACGME residency programs? If letters of M.D. are that important for competitive ACGME residency programs (even surgical residency programs), then isn't CaribbeanMD > DO?
