Bethesda Workshops 

a place for healing from sexual addiction in Nashville, TN


Sexual addiction is a complex issue, but there is hope! Many of our clinical staff are trained Certified Sex Addiction Therapists (CSAT®) or CSAT® candidates through the Institute for Trauma and Addiction Professionals (ITTAP). This training, developed by Dr. Patrick Carnes, requires attendance at multiple training modules and supervision with a CSAT® supervisor. It also requires ongoing education requirements so that CSATs are experts in providing the latest innovations in sexual addiction therapy. CSAT® training is a rigorous process designed to help professionals best serve their clients.
To learn more about treatment for sex addiction, visit This website also has links to for helpful resources for potential addicts and their partners: an initial (free) sexual addiction screening assessment and a partner sexuality survey.
