Homelessness is a prevailing social problem, and in many cases, it leads to psychiatric illness or vice versa. For most homeless persons with mental illness, accessibility and continuity of psychiatric treatment are an exceptional option due to their nature of life style. This case report (single-subject research design) highlights how a homeless person with mental illness was engaged with the treatment and psychosocial rehabilitation by utilization of community resources and reintegrated with the family through a case management approach in a community mental health center.
