You will be most likely to do OMM/OMT at a program that has DO attg's that actually use it a lot themselves. This applies to both ACGME and aoa programs.As many of us have seen on rotataions, just b/c someone is a DO does not mean they use OMM.
The other solution is to find a program which allows electives where you could rotate with a OMM specialist.
In general, with the way osteopathic education is now, you can't be pasive about learning OMM/OMT, very rarely have I run into an attg. who encouraged my use of OMM, but almost all (MD>DO!!!) have been receptive. I will also treat them if they will let me-explaining exactly what I'm doing and giving them journal articles on spinal manip. for spinal pain.
