Other Sexuality and/or Identity Support

Otherkin and Therian Experiences

We offer affirming, scientifically-informed clinical support to individuals who experience feelings related to, or who identify as, otherkin or therians. Our clinicians provide an open and non-pathologising space to explore the personal, relational, and psychological significance of these identities, and assist clients in navigating challenges related to authenticity, disclosure, community belonging, relationships and self-understanding.
‍
We also work with parents and partners of those with non-human feelings or identities who are seeking to understand these experiences and gather psychological strategies on how to provide appropriate support for their loved ones (including in the context of neurodivergence or mental health challenges).
