Carl Whitaker, MD, was an American physician and psychotherapy pioneer family therapist. Whitaker is most well-known for acknowledging the role of the entire family in the therapeutic process. He is the founder of experiential family therapy, or the symbolic-experiential approach to therapy. Rather than scapegoating one family member or even a specific family problem, experiential family therapy looks at the entire family system. Several other approaches to family therapy have drawn heavily from Whitaker's theories.
