An Abhainn means "The River" in Gaeilge (Irish Gaelic). Muir, the practitioner behind An Abhainn, is a student of Gaeilge and has an enduring fascination with recovering and reconnecting to the fragmented and suppressed wisdom held by their ancestors. They are inspired by animism, abolition, working peoples' solidarity, Indigenous liberation, acts of kindness, and anarchism: they seek to find opportunities to ally with collective liberation throughout all of their work. Muir is a facilitator, licensed massage therapist, trained conflict mediator, and mindful movement teacher living and working on occupied Chinook land.

Muir received their first facilitation training in 2015, at which point they fell in love with the practice and began to view all their work through the lens of the facilitator. Their original bodywork training in 2017 kicked off an ongoing, winding, and at times achingly rocky exploration of somatics, pain, and trauma. This exploration has led them through a grief work mentorship program, extensive training and study in equity-informed conflict mediation, and restorative/transformative justice facilitation practices. They also have an active interest in martial arts (they hold a blue belt in Brazilian Jiu-Jitsu), animist ritual, ancestral skills, singing, and decolonial land-based (re)connection work. They believe that the overall wellness of humans can only extend as far as the wellness of the land we call home.
