Psychotherapist in training under Supervision

The curious paradox is that when I accept myself,

just as I am, then I can change

As a person-centered therapist, I believe in the potential of every individual to find their own solutions and resources. My goal is to help you identify and utilize your strengths to achieve your goals and live a fulfilling life. Here are some reasons you might consider seeking support from me:

  • Feeling stuck, lacking progress, or trapped in negative thought patterns

  • Dealing with the aftermath of a traumatic experience or illness

  • Struggling with your sexual orientation or feeling isolated in your identity

  • Navigating life transitions such as job changes, separations, or loss

  • Feeling overwhelmed by responsibilities and lacking energy or motivation

  • Experiencing inner tension or fear that limits your ability to fully engage with life

In our sessions, I will provide a safe and non-judgmental space for you to express your thoughts and feelings without fear of criticism or pressure to conform to a certain way of thinking. Together, we will work to strengthen your self-confidence and self-acceptance, and to identify and overcome limiting beliefs and behaviors. My approach is based on empathy, active listening, and collaboration, and I am committed to supporting you in your personal growth and development.

In an initial consultation, we can look at your concerns, needs and current situation together. We can clarify whether and how psychotherapy can help you.

I would like to give you an insight into how I work and we can discuss the general conditions. The therapy can take place in German or English.  

Our general conditions

In my work as a psychotherapist, I am subject to a duty of confidentiality. This means that you can rely on my discretion during and of course after the end of the therapy.


The corona virus is forcing us into new forms of psychotherapy. After a personal (“offline”) initial consultation, I also offer psychotherapeutic coaching online via video telephony or classic telephone calls.
