Juan Manuel Delfin

Managing Director

Hola! I've been a Londoner since 2005, I moved here from my hometown of Barcelona, where I worked in film dubbing and sound design. I came to London to work with film ADR but I heard about and was intrigued by the work OM were doing with games. I responded to a job ad and joined the OM team as a freelance engineer in 2008. After three years I moved into production and studio management and in 2013 I was appointed Director of OM with responsibility for the London studios, taking the reigns as Managing Director in 2019. I still get to follow my audio heart, engineering, doing ADR and other audio magic. When not cycling and running I am perfecting my considerable coffee roasting and making skills. I get the OM crown for best coffee maker. Table tennis will come next.

I had the enormous privilege of growing up alongside mentors who were inventors and innovators who questioned everything. I inherited their fearless bug and OM is the result. The vision for OM was to establish ways to help actors perform at the peak of their ability in games. Little did I know it would take me into the world of spies, into psychology, software design, teaching, dramaturgy and redesigning recording studios ground up. I love the journey and the team. In my down time I write, walk, cook, brew, scuba dive, modify motorcycles, experiment with improv and ideas for eco living, and I hug my family whenever I can.
