Credentials
Shaped by experience, learning, and a passion for healing
Oskari Ventilä
Licensed Medical Doctor & Psychotherapist (CBT)
Specialist in Psychiatry
IFS (Internal Family Systems) Level 1 Trained Practitioner
I’m a licensed medical professional and psychotherapist working in the fields of mental health and substance-use disorders. I’m currently transitioning into private practice through my own therapy company. My mission is to support holistic well-being. Compassion, presence and constructive ways of relating are the foundation of my daily work.
I hold a specialization in psychiatry and addiction medicine, a four-year training in Cognitive Behavioral Therapy (CBT) and Level 1 training in Internal Family Systems (IFS).
I have a special interest in psychedelic-assisted therapies — I completed an additional 200-hour training through the Integrative Psychiatry Institute (2022), explored the topic in depth in my psychotherapy thesis (2022) and contributed to Finland’s first clinical trial on psilocybin-assisted therapy for alcohol use disorder as a research therapist (2024). Over the years, I’ve also had the joy and opportunity to teach students and fellow clinicians on the topics of psychedelics, psychiatry and addiction medicine.
