GCMHP was established in 1990 by the renowned Palestinian psychiatrist and human rights defender, Dr. Eyad El-Sarraj, as an independent, non-governmental, and non-profit Palestinian organization. Since its inception, GCMHP has worked to respond to the urgent need for community-based mental health services in the Gaza Strip by providing comprehensive and specialized mental health care to the population. GCMHP delivers its services through three community centers located in Gaza City, Deir El-Balah, and Khan Younis. These centers are staffed by multidisciplinary teams including psychiatrists, psychologists, social workers, psychiatric nurses, rehabilitation and occupational therapists, pharmacists, and medical secretaries. The programme provides preventive and curative services across primary, secondary, and tertiary levels, including consultations, psychotherapy, and occupational therapy.
