The Massachusetts Association for the Treatment of Sexual Abusers, Inc. (MATSA) is a non-profit local chapter of the national parent organization. It was formed in 1995 to carry out the mission of ATSA at the state level: to promote responsible assessment and treatment practices for adults with problematic sexual interests, behavior, or offending.
MATSA currently has over 100 members in Massachusetts and surrounding states. MATSA co-sponsors an annual multi-day training conference that hosts over 800 professionals from across the region and offers educational opportunities with local, national and international experts in the field. As such, MATSA places a high value on the research and application of the most effective means to combat and end sexual abuse.
Membership in MATSA is automatic when you join ATSA and live in Massachusetts. The ATSA membership application can be obtained from their website at www.atsa.com.
The Association for the Treatment of Sexual Abusers (ATSA) is a non-profit, interdisciplinary organization that was incorporated in 1984 by a small group of clinicians in Oregon who were working with sex offenders. ATSA remains dedicated to principles that foster research and information exchange, further professional education, and advance professional standards and practice in the field of sex offender evaluation and treatment. ATSA is now an international organization with over one thousand members committed to the prevention of sexual assault through effective management of sex offenders. ATSA promotes the philosophy that empirically based assessment, practice, management, and policy strategies will: enhance community safety, reduce sexual recidivism, protect victims and vulnerable populations, transform the lives of those caught in the web of sexual violence, and illuminate paths to prevent sexual abuse.
