This paper describes a unique situation in which disaster intervention following a massive earthquake led to significant, uninterrupted, psychosocial benefits to the entire country, and an intervention program that continues to evolve. The mental health program initially provided service to the victims, and then, training to local professionals during which personnel simultaneously conducted clinical research. Members of the mental health team made a life-long commitment to the country, and continue their activities to expand its impact on public health policy. The difficult history and life circumstances of the Armenian people provided the opportunity for disaster interventions to have extensive psychosocial benefits.
