Stenders had a long lasting career in radio starting with local radio stations. Stenders followed up Edwin Evers in the 3FM morning show "Stenders Vroeg" for the public radio and television company "VARA". In 2004 Stenders and his sidekicks moved to the commercial radio station "Yorin FM" and renamed his show "Stenders vroeg op". When Yorin was bought by SBS the name changed into Caz! and the format of the station changed, upon which Rob Stenders decided to quit. Between April 2006 and May 2007, he temporarily was no longer a DJ on national radio. He remained at his own internet radio station KXradio and he has had his own late-night show on Dutch TV-channel Tien.
Starting 7 May, he is back on the public network radio station 3FM with his new show "RobRadio" Fridays between 14:00 and 16:00. And Stenders Late Vermaak Fridays 22:00 and 01:00.
