Born in The Netherlands, Koen moved to Los Angeles at the age of 19. At an early age it was obvious he was destined for a career in the music industry; beginning with attending music school at the tender age of 6 and accelerating through his teenage years as a music producer. Koen’s love for music production was eventually replaced by his passion for the art of mixing down music.  

Not long after moving to Los Angeles, Koen gained the friendship of legendary GRAMMY® Award winning mixing engineer Dave Pensado (Michael Jackson, Beyoncé, Elton John). Dave’s friendship proved to be instrumental in Koen’s development and career as a mixing engineer.   

Koen’s unique talent didn’t go unnoticed and caught the attention of 3x GRAMMY Award nominated producer Dem Jointz (Dr. Dre, Janet Jackson, Rihanna). The two forged an amazing chemistry which led to Koen becoming the in-house mixer for Dem’s “U Made Us what We Are” brand.  

With his extensive technical, creative background and humble approach; Koen continues to work with the who’s who of today’s popular music and is a trusted face for top pro audio brands and an officially listed partner with Apple® for Mastered for iTunes® (MFiT). 

Koen currently resides in Los Angeles, California.
