Welcome to the APT Play Therapy Channel. Just as adults use words to communicate, children use play. Licensed mental health professionals therapeutically use play to help clients, particularly children, to express themselves and work out their problems. The Association for Play Therapy (APT) was formed in 1982 to advance play therapy and provide information, training, credentialing, and networking opportunities to its member psychologists, counselors, marriage and family therapists, and clinical social workers.
