My only concerns before taking this training were about my own lack of knowledge regarding DnD rules and how to incorporate therapy modalities. This training helped me in a few different ways: I now have a better understanding of how to incorporate my therapy modalities with DnD in a group setting; I feel more confident in my skills as a GM. It's difficult to choose one best thing about this training, there were many best things. :) I'd say the creativity I experienced with the training cohort members; the inclusivity, the camaraderie; the humor; the playfulness of each player. The knowledge I take from this training is the last best thing!
