Group therapy is a form of psychotherapy in which a small group of people is treated and covers several different methods. The main types of groups are a process group, a support group, and an educational or skills-based group. These are not necessarily distinct categories. For example, an educational group may have support elements. See below for descriptions and benefits of group methods. Group work is a tremendously rewarding opportunity for connection, sharing, and transformation as members learn and grow from their work and each other.
