Mental health care shaped by experience and humanity

Our story

Dr. Imer Önder Slettedal (b. 1976) was born and raised in Istanbul, Turkey. Following the completion of her medical degree, she relocated to Oslo in 2001 and obtained her full licensure as a Norwegian medical doctor in 2005. Upon completing her medical residency, she commenced her career in psychiatry in 2006. Dr. Slettedal has since completed an extensive dual specialization, qualifying as a specialist in both Adult Psychiatry and Child and Adolescent Psychiatry.

She possesses broad and diverse clinical experience from several of Norway’s leading medical institutions, including Oslo University Hospital, Diakonhjemmet Hospital, and Lovisenberg Diakonale Hospital. Throughout her distinguished career, she has practiced across a wide range of specialized departments: Child and Adolescent Psychiatric Outpatient Clinics (BUP), Adolescent Psychiatric Departments (UPA), District Psychiatric Centres / Adult Outpatient Clinics (DPS), Outpatient Clinics for Personality Psychiatry, Psychosis Outpatient Clinics and Acute Psychiatric Wards, and Psychogeriatric (Old Age Psychiatry) Departments at N.K.S. Grefsenlia.

In addition to her psychiatric credentials, Dr. Slettedal is an accomplished psychotherapist. She completed her advanced training in Family Therapy in 2015 under the auspices of the Regional Centre for Child and Adolescent Mental Health (RBUP) and the Institute of Family Therapy in London. In the autumn of 2023, she further expanded her clinical repertoire by completing a specialization in Group Therapy through the Institute of Group Analysis (IGA).

Dr. Imer Önder Slettedal holds a dual specialization in both Adult Psychiatry and Child and Adolescent Psychiatry. She provides tailored diagnostic evaluations and evidence-based treatments for children (from age 6) and adolescents, adults, and older patients. Dr. Slettedal provides comprehensive clinical care across multiple modalities, including individual therapy, family therapy, and group therapy, alongside professional counseling and clinical guidance. As a licensed medical doctor and specialist psychiatrist, she also expertly evaluates, initiates, adjusts, or manages the cessation of pharmacological treatments based on each patient's clinical indications.

The name MareSante has Latin roots: "Mare" means sea, and "Sanitas" represents health. The core philosophy is inspired by the perspective that life can be envisioned as a journey at sea. Each of us navigates our own vessel, steering through open waters, exploring new horizons, anchoring in different harbors, and gathering invaluable experiences along the way. To ensure the journey remains safe and fulfilling, it is vital to maintain control of the helm and hold a steady course.
