I'm not sure why this split is in the DIR forum . . . if the OP is specifically looking for "DIR" training, the choices are GUE, possibly some UTD instructors, and then specifically trying to find a GUE or UTD-trained instructor from another agency who has adopted the protocols.
Otherwise, there are, as I already posted, a great many other options for technical or cave training.
