About MareSante · 02
Mental health care shaped by experience and humanity.
MareSante Mental Health was established by psychiatrist Imer Onder Slettedal and offers assessment and treatment of mental health problems.
Imer Onder Slettedal was born and raised in Istanbul, Turkey, and has lived in Oslo since 2001. He is educated as a medical doctor, is a specialist in child and adolescent psychiatry, and is currently specializing in adult psychiatry.
His experience includes outpatient and inpatient clinical services across child and adolescent psychiatry, adult psychiatry, personality disorders, geriatric psychiatry, and psychosis. He has also completed education in family therapy through RBUP and the Institute of Family Therapy in London.
MareSante comes from Latin: “mare” for sea and “sanitas” for health — a reminder that life can feel like a journey at sea, and sometimes guidance helps us find the course ahead.
