Internal Family Systems (IFS) and Family Constellations are the two therapeutic frameworks at the root of tnf — the New Field synthesis. IFS asks what part of you needs to be seen; Family Constellations asks whose story you’re living and whether it belongs to you. The key structural claim of tnf is that neither framework alone is sufficient — something in the field moves what knowing alone cannot. IFS can be named and taught directly at mmh’s advanced-practitioner level; tnf is the next rotation past that point, reached through sufficient sgbh facilitation work.
