The Association for the Treatment and Prevention of Sexual Abuse is an international membership organization with 22 state chapters in the United States. These chapters play a critical role in ATSA's efforts to address the professional needs of our members and support sound research, effective evidence-based practice, informed public policies, and comprehensive collaboration designed to prevent sexual abuse. Each chapter meets regularly and offers peer networking opportunities.
