About me

Mag. Lorenzo Sleiter, MBA

I am registered as a psychotherapist (cognitive behavioral therapy) in Austria, entry in the list of psychotherapists in accordance with Section 17 (5) of the Psychotherapy Act, Federal Law Gazette No. 361/1990 (PthG).


  • German and Italian: native speaker/bilingual
  • English: very good
  • Spanish: good

I graduated from the German School of Rome, where I grew up bilingually, and have been immersed in German and Italian culture from an early age. I have now been living and working in Graz for many years and have thus been able to get to know and appreciate the culture and lifestyle in Austria as well.

After completing a business administration degree in Italy, a masters degree in human resources management in Ireland and several years working for companies in Germany, Italy and Austria, I decided to pursue a new professional path and undertake the 6-year training course in psychotherapy in cognitive behavioral therapy at AVM (Working Group for Behavioral Modification) in Graz and Vienna.

My previous employment taught me a lot, particularly on a personal level, which I was able to reflect upon during my psychotherapy training. In my current psychotherapeutic work, I draw upon both my own work experience and experience of living in different countries in Europe to better help my patients.

Since 2021 I have been on the list of psychotherapists (with the specialization in cognitive behavioral therapy) at the ministry in austria.  From February 2019 till March 2020 I have worked in a psychosocial counseling center in Leibnitz (Psychosocial Service Leibnitz) and in my own practice in Graz. From April 2021 I am working at the “Institut für Psychosomatik und Verhaltenstherapie” (IPVT),, in Graz.

In 2022 I completed the training in Imagery Rescripting and Reprocessing Therapy (IRRT) with Prof. Mervyn Schmucker and obtained Level 1 certification in 2023.

Since 2022, ongoing further training in clinical hypnosis according to Milton Erickson at MEI in Graz.

Previously, I completed internships at the Aloisianum in Graz, a residential community for alcoholics, and at the LKH Graz II in the PS24 station, an area of the hospital dedicated to women with subacute psychiatric disorders. These placements offered me important insights into the clinical work involved in psychiatry and were both very important and fulfilling educational experiences for me.

I am now looking forward to delving deeper into the behavioural therapy field and growing my practice in Graz.
