Great as a visual for my clients.
Format: Spiral-bound
I highly recommend this chart. In my practice as a therapist I often go over boundaries with my clients and this is a good guide and visual for my clients rather than using the computer or sheets of paper. Clients have reported that it’s really helped them to understand more in our sessions about boundaries good quality and it’s erasable with the right markers.
