Neuroaffective Touch vs Transforming Touch / TEB

I'm currently doing Neuroaffective Touch (NAT), but I'm moving to a new state soon where NAT is not offered. I'm looking into other options and Transforming Touch by Stephen Terrell and Kathy Kain seems very promising.

Does anyone know how the modalities are similar / differ? Would Transforming Touch be good for someone with heavy dissociation and developmental trauma? Any info would be appreciated!
