Therapeutic
practice
I consult, support, and provide short- and long- term therapy for a wide range of mental health problems. My specialization includes the integration of psychedelic experiences and psychotherapy of addictive behaviors. I work with adolescents and adults, in both English and Polish. Consistent with my eclectic nature,
I employ several psychotherapeutic approaches, adapting their methods and perspectives to the current needs of the therapeutic work. I am continuously pursuing further education in this regard, and I conduct my practice under constant supervision.


Organizing
workshops
Together with my partner, Kami Glazer, we co-organize an international retreat “Connections” dedicated for everyone wanting to deepen their relationship with themselves and others.
I also lead the workshop “Psychedelic Integration in Practice” for students in the “Psychedelics and altered states of consciousness: applications in psychotherapy and medicie” postgraduate program at the SWPS University. I also regularly collaborate with various foundations, institutions, and companies, conducting workshops on psychoeducation and prevention of addictive behaviors.
As part of the cooperative initiative “LIMINAL,” which I co-founded, I have conducted over a dozen workshops on the theory and practice of integrating psychedelic experiences, attended by more than 200 mental health professionals.
