Bringing Integrative Healing to Psychedelic-Assisted Therapy

ATMA Provides A New View to Mental Healthcare

ATMA provides psychedelic therapy education and training to practitioners so you can offer this ground-breaking treatment to your mental health clients.

A means to incorporating Psychedelic Therapy


Psychedelic-Assisted Therapy Training

Through the unique healing and transformative experiences of psychedelic-assisted therapy, we are witnessing a new frontier of treatment that is providing hope to those struggling with chronic, treatment resistant mental health concerns.

ATMA’s psychedelic therapy courses establish a standard of care for which mental health professionals should be trained to use psychedelics in their practice. Regulatory changes are occurring rapidly; healthcare professionals who achieve competency in this area will be uniquely positioned to adopt psychedelic therapy treatment into their practice immediately upon legalization of these medicines.
