Van Pooss worked in the media industry for nearly 40 years and was most recently group national sales director at local radio company UKRD. He was formerly managing director at Active FM and Essex Radio.
Paying tribute to his colleague, William Rogers, chief executive at UKRD, said Van Pooss' death was a "real loss".
Rogers said almost everyone who met Rob will have encountered one of those "larger than life characters" who lived, slept and breathed the job he did.
Van Pooss, known as RvP to many, was "well read, articulate, witty and creative" and able to grasp the most complex of issues and convert them into simple and easily communicated messages, said Rogers.
Rogers added he had crammed more than one life into his 60 years and many would have to have lived two or three times to achieve everything he did and that his thoughts were now with "Maggie, Toby and Nick and the rest of the family van Pooss".
