MUDr. Filip Tylš, Ph.D.


I am a psychiatrist and neuroscientist working at the Czech National Institute of Mental Health (NÚDZ), where my patients include those with neurotic and psychotic spectrum disorders. I also participate in psychedelic research (EEG correlates of psychedelic experiences) and, more significantly, in psychedelic-assisted psychotherapy (PAP). In the course of my studies of psychotherapy, I have been influenced by experiences induced by various psychedelic substances, sweat lodges, holotropic breathwork and traditional ayahuasca rituals. I graduated from the 1st Faculty of Medicine, Charles University (2012) and proceeded to complete a PhD programme in Neuroscience at the 3rd Faculty of Medicine (2017), where I became an assistant lecturer. At NÚDZ, I am a member of the team conducting pilot clinical trials of psilocybin administration to human subjects (as a psychedelic sitter). In 2015, together with a group of professional friends, I helped establish the Czech Psychedelic Society (CZEPS); and, since 2017, I have been assisting people manage difficult psychedelic experiences as a member of the Psycare team Additional specialized training courses have included Gestalt Psychotherapy (IVGT Prague; 2014–2020), Psychedelic-Assisted Therapies and Research Certificate Program (CIIS USA; 2018) and MDMA Therapy Training Program for PTSD (MAPS USA; 2019).


I offer individual psychotherapeutic counselling sessions to both adults and adolescents using the dynamic Gestalt therapy approach. This approach is experience-oriented and is focused on expanding the client’s self-awareness in the here and now, with an emphasis on achieving a unity of mind, emotions, and body. My approach is based on authenticity of contact and reliance on the inner process. I aim to provide a space for self-expression (without judgement) and I partner with my clients on this journey (non-directional coaching), ensuring the confidentiality of this communication and experience. I focus on personality issues, relationship issues and on the understanding and integration of difficult life experiences. To achieve these goals, I employ guided imagery, symbolism and metaphor.


Both long-term cooperation and short-term crisis interventions are possible.
