About me

I consider my professional activity to be a great privilege and the joy of work is an important part of it for me. In my work, authentic, empathic contact at eye level is important to me. The trust that my clients place in me is a great honor for me.


In the sessions I will accompany you through difficult phases in life, with mental illnesses, in crises or on the way to personal development. My goal is to work with you to find out which patterns and experiences have contributed to the current situation in order to find new ways to deal with it.


I am happy to provide my knowledge and skills that I have gained in the course of my training and my professional activity.
