Association of Systemic Therapists (AST) is a nongovernmental organization founded in 2005. The members of the Association are both internationally and nationally certified psychotherapists. They form a team of trainers who lead and carry out the systemic family therapy training program.

AST has a status of European Accredited Psychotherapy Training Institute, issued by EAP.

Psychoeducational sessions are delivered in many different formats: individuals, couples, families, family groups, organizational teams, etc. The training program and the entire curriculum have been created and are based upon the updated evidence-based practice. The continuous challenge for systemic therapists and the training programs has been to maintain coherence and comprehensiveness of the multi-modal approach when working with families.
