What is Janina Fisher Trauma-Informed Stabilisation Treatment (TIST)? And why might I be interested in it?

Why would I be interested in working with a therapist who utilises Janina Fisher’s Trauma-Informed Stabilisation Treatment (TIST)? TIST provides the possibility of moving from feeling chaotic, confused & distressed by our trauma responses towards listening to all parts of our experiencing and making considered responses from that place.
