Küsnacht,
A precision-psychiatry residence on Zurich's Gold Coast that treats the biochemistry first and reaches for psychiatric medication last.
CALDA Clinic works without psychiatric drugs wherever that is clinically possible, and that single commitment shapes everything else it does. It delivers the CALDA Concept: a diagnostic-first model combining conventional medicine, orthomolecular and metabolic medicine, complementary therapy and Asian medicine disciplines, under a founder who is a specialist in psychiatry and psychotherapy. Clients begin with a one to three day medical evaluation at the Bethanien partner clinic in Zurich, then are treated one to one in a private serviced villa with a butler, private chef, interpreter and chauffeur. The therapeutic programme is intensive: six to eight hours a day, seven days a week, with a primary phase of at least four weeks. The clinic states that it cares for one client at a time, but publishes no bed count, residence count or occupancy figure against which that statement can be checked. The founding year is unresolved: the clinic gives 2008, the operating company was entered in the Commercial Register on 20 October 2004, and a third-party directory states 2015.
The clinic publishes a named roster across leadership, medicine, psychology, nutrition and a scientific advisory board on its own core team page.

Minimum four weeks, six to twelve weeks often optimal
From CHF 116,000 per week
One-to-one residential treatment in a private serviced villa following the diagnostic phase. The programme runs six to eight hours a day, seven days a week, under a personal lifestyle and diet coach, combining intensive psychotherapy with orthomolecular and metabolic medicine and avoiding psychiatric medication wherever clinically possible.
One to three days
Included in the inpatient programme
A medical evaluation at the Bethanien partner clinic in Zurich producing a multidimensional diagnostic profile: laboratory and clinical-chemical tests, micronutrient and hormonal analysis, epigenetic and molecular testing alongside psychiatric assessment. This diagnostic-first sequencing is the structural basis of the CALDA Concept.
One week
-
The clinic's only programme explicitly exempted from the four-week minimum. An intensive single-condition intervention for specific phobias, delivered in the same one-to-one residential format in a CALDA residence. No detailed protocol is published on the fees page, so it cannot be compared on cost.
-
CHF 32,000 one-off
Outpatient assessment and optimisation covering metabolic, hormonal and micronutrient status, producing a personalised protocol. It is the lowest-cost entry point into the clinic and the only outpatient product with a published price, which makes it the practical trial route before a residential admission.
-
-
A targeted micronutrient and biochemical restoration protocol derived from laboratory analysis, available as a standalone package as well as inside residential treatment. The clinic publishes neither a price nor a duration for it, so it is recorded here as published but unpriced.
The entire verifiable client review base is roughly ten reviews across two platforms, one of which is a single strongly negative entry. That is below the threshold for confidence in either direction. No evidence of review manipulation was found. The clinic's own case studies are not testimony: the imprint states that persons and actions in one section of client narratives are entirely fictitious, while the case studies page states that each case outlines a genuine therapeutic experience with details changed. Those two statements cannot both be true.

The clinic is listed by Switzerland Tourism on myswitzerland.com, and the founder has appeared on CNN Money Switzerland. No tier-one hard-news coverage was found, and no independent facility visit by any journalist was found.
The European Award in Medicine in the Addiction Treatment category, and a 2019 European Awards in Medicine listing in Rehabilitation. Both come from a commercial European awards body, not from a clinical or accrediting authority, and are not accreditation.
Treatment is delivered in handpicked private villas, fully serviced and tailored to the individual client, in elevated positions on Zurich's Gold Coast with panoramic views over Lake Zurich and the Alps. Each property is described as furnished to a premium standard and designed as a secure, peaceful setting. Accompanying family members are placed in nearby luxury hotels rather than in the residence. The clinic publishes no residence count, no floor areas, no room counts and no verified interior specifications, and no photograph of any CALDA residence appears on its own website. No journalist has been admitted for a facility visit.
A private chef is part of the standing service team in every residence, alongside a butler, an interpreter and a chauffeur. Four private chefs appear on the staff roster, none of them named. Nutrition is clinically owned rather than treated as hospitality. A graduate nutritionist holds the named post of Head of Integrative and Metabolic Lifestyle and Nutrition, and meals are calculated from the client's orthomolecular diagnostic results, so diet is an instrument of the metabolic-psychiatry approach. No chef is named and no fine-dining credential is published.
single occupancy per residence
What is established: unmarked private villas in a residential district, no shared facilities and no group therapy, an explicit policy that treatment is conducted inside the CALDA residences rather than at external venues, and accompanying family housed off site in partner hotels rather than in the residence. The one to three day diagnostic phase is the exception, since it takes place at a partner hospital in Zurich that the clinic does not control and for which no separation arrangement is published. What is not established: any number. The clinic states it cares for one client at a time, but there is no published bed count, residence count, occupancy figure or floor plan to test it against, and residences are referred to in the plural. It should be reported as the clinic's claim, not as an established fact.
Headline basis: Public evidenceThe headline number is the public score, not the extended score., LROAS 1.0.0, edition 2026-10-01
Public-evidence total: 51
The sum of the ten criterion scores, from 10 to 100, using evidence anyone can check, including the clinic's own pages as self-declared statements. For the licence element of C2 only, it can also use an authority ruling held in our sealed evidence room. It is the only number used for the rank.
ConfidenceHow well the evidence supports the score.: medium. ProvisionalA check was still open when the edition closed, for example a register lookup or a video not yet received, or evidence under embargo.: C10.
Scored on the occupancy model only; no bed count or capacity figure is used. The FAQ states the clinic cares for one client at a time and houses the client in a private residence, which is single occupancy per residence, and no group therapy is published. Band 9 is not reached because there is no explicit statement that clients never meet, no published separation or scheduling for the one to three day diagnostic phase at the partner hospital Bethanien, and only one confidentiality mechanism beyond statute (self-funding) is named. No deduction applied; the plural 'residences' wording is not treated as a contradiction because no concurrent residence count is published.
ConfidenceHow well the evidence supports the score.: medium
Psychiatric care by a psychiatrist is stated for this site and a physician Medical Director makes the final admission decision. No institutional operating licence was found: calda ag appears in the federal UID register as a company, which is not a licence, and the Canton of Zurich publishes no list of licensed ambulatory institutions, so the licence is recorded as absent rather than as a finding against the clinic. Overnight physician or psychiatrist cover is not established, withdrawal care (opioid detoxification) is delivered at the partner hospital Bethanien rather than on site, Bethanien is not named as an emergency escalation route, and no accreditation was found on an accreditor's register.
ConfidenceHow well the evidence supports the score.: high
Every programme opens with psychiatric evaluation and a one to three day medical check-up, partly at the partner clinic, covering a laboratory panel, general medical evaluation, micronutrient, hormonal and genetic or epigenetic analysis. The band above is not reached because no clinical screening before commitment is published (no referral letter or in-person pre-assessment is required) and no written diagnostic formulation for the client is published.
ConfidenceHow well the evidence supports the score.: medium
Daily one-to-one core sessions including psychotherapy and medical consultations, seven days a week, are published and support band 5. The six to eight daily hours cover the whole programme including coaching and complementary therapies, with no clinical share published, so they are not counted as clinical contact. Senior clinician concurrency and 24-hour clinical presence are not established, which keeps the clinic below the band above.
ConfidenceHow well the evidence supports the score.: medium
Three aftercare elements are published: a tailored transition plan, the clinic's own Continuing Care phase that can be delivered at home, and remote sessions with laboratory monitoring. The duration is only 'several weeks to a few months', the post-treatment programme is excluded from the price, and no psychiatric follow-up or family involvement after discharge is described, so the band above is not reached.
ConfidenceHow well the evidence supports the score.: medium
A sweep of the clinic's own domains found no self-ranking site, no sponsored recognition presented as accreditation and no assistant-directed content (/llms.txt and /ai-instructions/ returned HTTP 404). The European Awards in Medicine item on the news page is presented as an award, not accreditation, and scores nowhere. No positive signal counts: the fees page states fees vary with each client's needs, no referral-fee position is published, and no exclusion criteria or voluntary-admission policy are published, so the clean sweep places the clinic in band 4.
ConfidenceHow well the evidence supports the score.: low
Three transparency elements are met: fee inclusions and exclusions, deposit and refund terms (50 percent non-refundable deposit, balance two weeks before start, no refund on premature termination), and the legal operating entity calda ag with UID and address. Extension terms, a licence reference, an ownership statement beyond 'private, owner-operated', a complaints route and a retention period are not published. No contradiction deduction applies: the CHF 116,000 weekly floor and the CHF 496,000 one-month Full Program agree within 0.23 percent on a 30-day basis, and a comparison of 88 price pairs across the English, German and Spanish pages found none in conflict.
ConfidenceHow well the evidence supports the score.: high
No final regulator, court or tribunal finding, licence action or inspection record against calda ag was found; the one Swiss court decision located mentions the company name only in bookkeeping and is not a proceeding against the operator. No inspection record is published, no bylined first-hand reporting from inside the facility exists, and there is no second independent review platform (no Trustpilot profile), so the clinic sits in band 5, the 'not published' band.
ConfidenceHow well the evidence supports the score.: low
The score is the mean of a health and safety sub-band of 4 and a nutrition sub-band of 5, 4.5 rounded half up to 5. Nutrition is supported by a named graduate nutritionist and meals calculated from orthomolecular results. The emergency distance element is not met: the verified 8 minute route to Spital Zollikerberg starts from the registered seat in Küsnacht, which is not presented as a treatment address, and the residences are named by region only, so the distance cannot be attached to the place of care. No therapy room, medication policy or nutrition monitoring during the stay is published.
ConfidenceHow well the evidence supports the score.: medium
A MedReg lookup confirms the Founder and Medical Director holds the federal specialist title in psychiatry and psychotherapy, and six further listed physicians are confirmed on the federal register; one listed doctor returned no match and one psychologist is not recorded in PsyReg. Archive captures from 2021 to 2025 confirm continuity of the Medical Director title, which is not a credential. No university appointment, doctorate source or publication record is verified, so the band above is not reached. The facility licence cannot be proven from the cantonal site, so the score is only partially recomputable.
ProvisionalA check was still open when the edition closed, for example a register lookup or a video not yet received, or evidence under embargo.: Clinician register lookups for this criterion were still open at the edition cut-off (see known_gaps). The points count as assessed on the evidence available; the band may change when the lookups are completed, which is resolved in a later edition.

Inpatient programmes start at CHF 116,000 per week and the outpatient CALDA Longevity Package costs CHF 32,000, both as published on the clinic's fees page. The clinic publishes no total for a full stay on that page. Fees are individually quoted after assessment, an advance deposit secures the reservation, and treatment is not covered by health insurance. Prices for the specific phobia and orthomolecular packages are not published on the fees page.
On Zurich's Gold Coast. The administrative address is In der Hinterzelg 35, 8700 Küsnacht, confirmed in the Swiss Commercial Register. Treatment itself takes place in private villas whose addresses are not published, set in elevated, quiet positions with panoramic views over Lake Zurich and the Alps. The medical diagnostic phase is run at the Bethanien clinic in Zurich, and accompanying family stay at partner hotels rather than in the residence.
High-net-worth and ultra-high-net-worth individuals who want intensive psychiatric treatment without psychiatric medication wherever that is clinically possible. That commitment is the clinic's defining feature and it self-selects a particular client: someone who has often already been medicated elsewhere and wants a root-cause, metabolic and orthomolecular approach instead. The range covers addiction, trauma, depression, anxiety, eating disorders, burnout, bipolar and borderline conditions, alongside metabolic illness.
No doctor's referral is required. Admission begins with a confidential, non-binding consultation, after which the clinic builds a personalised offer. An advance deposit secures the reservation. The clinic then runs a one to three day medical evaluation at its Bethanien partner clinic before residential treatment begins. CALDA states that admission is typically possible within two weeks and that emergency admissions can be arranged. The Medical Director makes the final decision on admission.
The primary phase is a minimum of four weeks, with six to twelve weeks described as often optimal, and the clinic sets the timeline collaboratively. A tailored transition plan is described, and the clinic recommends a secondary Continuing Care phase lasting several weeks to a few months, which can be delivered at home and may include remote sessions, laboratory monitoring and scheduled follow-ups. No price is published and the terms exclude the post-treatment programme from the treatment cost, so prospective clients should establish the aftercare arrangement explicitly before admission.
