I share the concern expressed about the brevity of experience in a medical environment, as adcomms like to see longevity in this type of activity. What did you mean by "paraprofessional for autistic children?" Might that be construed or spun as clinical experience also?
Other schools within your stats range, considering you have 13 months of research, which have a decent OOS acceptance rate:
UVirginia, Emory, Brown, Dartmouth, Ohio State,
UCF, USCal, Boston, Tufts, SLU, Einstein, Rochester,
UConn, Georgetown, Miami, Iowa, Maryland, UMinn, Wake, Cincinnati, Penn State, UWisconsin,
Unless you are drawn to DO schools, have shadowed a DO, and can inteliigently discuss OMM at interviews, I see no reason to include some.
