As a trauma specialist often working in the areas of CPTSD and attachment traumas, I was thrilled to find Dr. Zack as both a therapist and trainer in Three Pillars therapy and the Ideal Parent Figure (IPF) protocol.  Zack offers detailed and knowledgeable discussion of attachment theory, screening methods and the skillful delivery of the IPF protocol.  His teachings are clear and delivered in a grounded and present manner.  I highly recommend him as a therapist, supervisor and trainer.
