About us

Asst. Lect. Dr. Bert te Wildt is a specialist in psychiatry and psychotherapy with an additional qualification in primary addiction medical care. Dr. te Wildt has been the Chief Physician of the Diessen Convent Psychosomatic Hospital on Lake Ammer since 2018. Here, he now contributes his longstanding experience and proven specialist knowledge. Most recently, he headed the Out-patient Clinic and Media Addiction Clinic of the LWL University Hospital for Psychosomatic Medicine and Psychotherapy of the Ruhr University in Bochum. Dr. te Wildt has worked as the Chief Resident in the Department of Psychiatry, Social Psychiatry and Psychotherapy at the Medical University of Hanover (MHH) for several years. Dr. te Wildt’s scientific and clinical focus is in the fields of behavioral addictions, internet addiction and online psychotherapy. The expert in online addiction is the cofounder of the Media Addiction Association, which has developed into a professional network since 2008. Dr. te Wildt’s doctorate on the topic of Comorbidity in Internet Dependency followed in 2009.

One particular achievement is the founding of the OASIS Online Addiction Clinic under the direction of Dr. te Wildt, which is supported by the German Federal Ministry of Health and which approaches internet addicts and meets them where their addiction started, namely in the digital world itself. With this application of digital technologies in psychotherapy, Dr. te Wildt wants to show that the positive side of the internet can also be utilized for internet addicts. Essentially, this does not involve surrendering to the digital revolution but taking control of the digital revolution and molding it in a positive fashion.

Dr. te Wildt also now implements this approach at the Diessen Clinic on Lake Ammer. Here, for example, digital virtual reality technologies are utilized in the treatment of anxiety and posttraumatic disorders. As well, the particularly extensive analogous cultural and natural environment in and around the convent are harnessed as therapy in order for the experience of peace and slowing down to counter the urban and digital environment.

Together with the treatment of behavioral addictions such as internet and shopping addiction, the service portfolio of the Clinic includes the treatment of all psychological conditions in the psychosomatic field. The program includes individual and group psychotherapy, as well as body psychotherapy, art and music therapy. Of course, detailed personal preliminary consultations, which can be conducted both in the Clinic itself and via a secure video conference system, lead the way for the indication and individual therapeutic planning.

Together with his leading positions over many years, as Chief Resident and now as Chief Physician in Diessen, Bert te Wildt is also engaged as a versatile author and editor of several textbooks and with contributions to specialist journals, as a publicist, lecturer and reviewer within the framework of his specialist expertise. Thanks to his scientific work, he has been awarded the Wilhelm Bittner Prize of the International Association for Depth Psychology and the Lebensnerv Foundation.
