What Is
Crucible Therapy?
Crucible Therapy is Dr. David Schnarch's approach to couples therapy. It is built around differentiation: learning to stay grounded, honest, and connected when conflict, desire, and emotional pressure rise in a relationship.
Core Ideas
These four ideas give the Crucible model its shape.
If you want to understand what makes this approach distinct, start with these concepts.
