He started dj-ing in 1992, it all started in a club called Habbekrats in Utrecht. Not long after the club transformed into a Mellow club called Shiva. Here started my career as a DJ and DJ DEF was born. He played there with big names for that time as 100% Isis, Robin Albers JD, Marcello, Dano, Dimitri and Freddy B. He got very wel known under the name: DJ DEF , so I was asked to run in various clubs in Utrecht and surroundings. Now in 2009 I'm still active as a DJ, I mix my DJ-Sets for radio stations called Radio D-Fusion and FTDtechnoTEAM Radio.
