The spirit Dr. Adolph Fritz and
medium Kleber Aran

In brief

The spirit of Dr. Adolph Fritz and medium Kleber Aran are an extremely interesting combo. There hardly is another doctor-spirit service attendance where the emotions are so expressively and palpably emitted by the incorporated spirit. Besides the treatment and surgeries at this place, the doctor spirit lovingly hugs and engages with each patient in a frank and amusing way but without losing the seriousness of the service. There also are quite many people who do not suffer from anything but simply come because seeing Dr. Adolph Fritz shouting, grumbling, and joking as he treats people is an exhilarating and unforgettable experience. Interestingly, one could easily mistake Dr. Fritz for a normal medical doctor when perusing the medical exams (CT, MRI, etc.) that some volunteers and regular visitors bring to ask for his opinion.


Watching medium Kleber Aran under the influence of Dr. Fritz leaves no doubt about what his mission is. On an average day between 300 to 800 people wait for the start of the service in a somewhat dated industrial hall that is filled with emotions and expectations – and flooded with hope, awe, and joy when Dr. Fritz greets the audience with a loud, grumpy-sounding but positive forceful shout.

Medium Aran is in full trance during the entire time Dr. Fritz remains incorporated in him. He does not consciously perceive nor remember anything that happens during that time. His characteristics – physical and mental – change notably.

The spirit Dr. Fritz says that he has chosen to work through the man Kleber Aran because he knows him from his previous life during the time of World War I. Back in that time, Aran had shown to be a man of great integrity – honest, upright, and trustworthy.

Simpleness and openness of service

What makes this entire experience so outstanding is that there is almost no hierarchy or precedence of treatment apart from the most urgent and severe cases are treated right at the beginning of the service. Although most people wait for their turn, at nearly any time it is possible to walk right up to the spirt-controlled Aran and share what it is that support or help is needed for. The volunteers, who orbit around him, are supporting and encourage the patient to speak with Dr. Fritz rather than shielding him.

The openness and welcomeness of the entire service are a true reflection of medium Aran’s honest account and willingness to share insights and experiences about his relationship with Dr. Fritz. Similarly, Aran’s humour and funniness seem to give this striking work an elevating and charming spin without losing its seriousness, importance, and intent.

The multitudes of new and returning visitors, who mainly come from north-west and west Brazil serve as an attestation of this amazing and exceptional work. And everybody who wants to see or experience Dr. Fritz working through the hands of medium Aran Kleber is invited to do so.


Medium Kleber Aran only speaks Brazilian Portuguese, Brazil’s official language. However, from the moment Dr. Fritz incorporates into Aran, Aran’s command of German is all of sudden very present. He can understand a German native speaker and usually respond meaningfully. His understanding of English, Dutch, Polish, Japanese, and some other languages becomes surprisingly good too. He might falter when replying in these languages, but his English, and even more his German, are the most solid ones. Regardless of the language Dr. Fritz speaks in a given moment, all of them remind of a guttural Prussian German. Interestingly, his Portuguese starts to suffer immediately, frequently using wrong gender forms, grammar, wrong words, often mixed up with German so that, at times, even the Brazilians have difficulties to understand and ask him to repeat what he has just said.
