Clinic in Hazel

What Clinic in Hazel does

Klinik Im Hasel AG is a Swiss non-profit specialty behavioral healthcare provider operating as an institution of the Von Effinger Stiftung, which was founded in 1911 to combat alcoholism; the clinic itself opened in 1974 and was restructured into a non-profit stock corporation in early 2014. The clinic treats co-occurring addiction disorders (substance-related including alcohol, medications, illegal drugs, and multiple dependencies, plus non-substance addictions such as gambling, internet, and shopping) and trauma-related disorders (PTSD from accidents, violence, war, torture, and other extreme stresses) across three integrated locations: Ambulatorium Lenzburg (outpatient addiction treatment and admission coordination hub), Ambulatorium für Traumafolgestörungen Baden (specialized trauma outpatient clinic), Tagesklinik Lenzburg (day clinic with full-day and half-day programs), and Klinik Im Hasel Gontenschwil (inpatient residential treatment).

The clinical technology stack is built on evidence-based psychotherapy procedures including EMDR, IRRT (Imagery Rescripting & Reprocessing Therapy), NET (Narrative Exposure Therapy), Somatic Experiencing, SiFi (Sicherheit finden), DBT, MBSR, Motivational Interviewing, and the clinic's proprietary Leistungssensible Suchttherapie (LST) approach. Treatment is delivered by an interdisciplinary team of 170+ staff spanning psychiatry, psychotherapy, nursing, art therapy, movement/body therapy, occupational therapy, and social work. The facility operates as an SIWF/ISFM-certified advanced training institution and holds ISO 9001, QuaTheDA, and SQS quality certifications.

The revenue model is fee-for-service healthcare funded by Swiss basic health insurance (Krankenkasse Grundversicherung) and cantonal contributions from the patient's residential canton, primarily Canton Aargau; no supplementary insurance is required. Go-to-market is referral-led: patients enter the system through family physicians, hospitals, psychiatric services, or social services, with Ambulatorium Lenzburg coordinating all downstream treatment placements. The clinic also runs an Akademie (Academy) for continuing education and a published methodology (the LST book) that extends the brand into training and intellectual-property channels.
