ÖKA Team
Meet Our Team
Our team brings together a diverse mix of personalities, all connected by sound — whether through therapeutic practice, crafting sound instruments by hand, or exploring the possibilities of sound.
Our vision: a place where people can experience sound, try it out for themselves, and use it to rest, recharge and relax. All in a playful setting with room to breathe.
Join us to share ideas, create, collaborate, make connections and get hands-on. Drop by for your next coffee and get to know us — and the world of sound!
The ÖKA team also brings professional expertise to our sound training programmes, Peter Hess® Sound Massage training and a wide range of workshops.
