There is no global credential. "Logotherapist" is not a protected title in any country. Here is what the three main routes actually require — and the distinction that most sites blur, stated on the page where it belongs.
A logotherapy credential sits in one of two places, and they are not the same thing:
Conflating the two is the field's most common and most serious misrepresentation. A site that calls its author "a logotherapist" and lets you assume (a) when the truth is (b) is doing the thing Frankl told logotherapists not to do. We are (b). See §5.
Figures below are from the bodies' own published documents as of September 2026 and will change; links are given so they can be checked.
The Vienna Institute accredits both institutes and individuals, through the International Association of Logotherapy and Existential Analysis (founded 2013). Accredited members subscribe to the ethical guidelines of the American Psychological Association and the German DVP.
What Vienna accreditation therefore is: an umbrella membership and quality-assurance scheme — document review, guarantors, a fee, renewed every two years — not a standardised competency examination. That is not a criticism; it is what the documents say. But "Vienna-accredited" tells you the institute is recognised, not how many hours its graduates trained.
The US institute (Blue Island, Illinois) runs a tiered credential:
This is the one route that publishes hour requirements — and note that its clinical tier is route (a) by construction: the licence must already exist.
The Gesellschaft für Logotherapie und Existenzanalyse and its national societies train Existenzanalytiker. In Austria this is the one logotherapy-descended route that leads to state registration as a psychotherapist under the Psychotherapiegesetz, and its requirements are correspondingly heavy — on the order of 72 days of group work, 50 hours of individual self-experience, 150 hours of group supervision and 550 hours of practicum, at a total cost in the region of EUR 27,000. It is the most rigorous training in the family. It is also, as the next section explains, the one Frankl walked away from.
Get this right or lose every specialist in the room.
The accurate framing: both lineages descend from Frankl. The Frankl-faithful lineage runs Vienna Institute → national institutes. The Längle lineage (GLE, and the ISEAP) is a methodologically divergent development that Frankl personally repudiated by resigning in 1991, and it is institutionally separate. Neither is "the" official body. A GLE-trained Existenzanalytiker is not a Vienna-accredited logotherapist, and vice versa — and a directory that lists them side by side without saying so is not doing its job. Ours says so.
One further irony worth knowing. Meaning-Centered Psychotherapy — the best-evidenced descendant of Frankl's work, with the trials on the evidence page — has no certification requirement at all. Trained clinicians work from a manual. In this field, evidence quality and credentialling formality are inversely related.
If you want to find a logotherapist, the existing public lists will not help you much, and that is the reason logotherapists.com exists.
The practice behind this site is route (b): logotherapy in Frankl's broad sense, as counselling and education, by a practitioner who holds no clinical licence and says so.
Concretely: the man who wrote this site coaches people daily, has taught for ten years as a volunteer in village schools in north-eastern Thailand, and teaches a meaning curriculum to young men with their fathers present. He is not a psychiatrist, psychologist or licensed psychotherapist. He does not treat disorders, does not diagnose, and refers anyone whose situation calls for a clinician to one. His authority to talk about meaning comes from the same place Frankl said all such authority comes from — people who have found it for themselves — and from the fact that everything on this site can be checked.
If you are looking for a licensed clinician who uses logotherapeutic methods, that is route (a), and the directory distinguishes them. If you are looking for someone to think alongside about what your life is for, with no claim to treat anything, that is here.
