About us

The ISPS EC is made up of people with a wide range of interests and experience, all of whom donate their time voluntarily, and all of whom are highly committed to the common aim of advancing education, training and knowledge of mental health professionals in the treatment and prevention of psychotic mental disorders for the public benefit.
