First, to answer even broader than your question, with the deep tissue work, Craniosacral work, anger expressive work, model mugging, and movement work, all facilitators were sufficiently experienced in working with people dealing with trauma, even though it wasn't their official title. This meant they understood the general process and were able to adapt to my specific needs: work at my speed, be empathetic, be present through emotions, and let me have the locus of control.
With Craniosacral Therapy, if the practitioner has gone through advanced classes of training, they will have recieved instructions in working with people dealing with trauma. For one method of training, you can search their experience @ Upledger Institute, then go to 'find a practitioner', then specify 'Craniosacral therapy', then specify your 'zip code', then when the practitioners names are displayed, look for someone who has completed at least level 3, and even better, level 4. Always good to find someone you relax with and like.
