Gordon Smith's career as a medium began at the age of 24, when another medium told him that one day he would be 'on the platform'. This was the start of a 15-year long study to be a medium. He works giving demonstrations, writing books and organising workshops, and until March 2008 wrote a psychic column for the British tabloid The People. Smith does not charge for readings.
In 2008, Smith appeared in a special "Paranormal Edition" episode of The Weakest Link, in which he made it to the final round but lost to Mia Dolan. In 2008-09, he presented his own series 'Psychic Therapy' on the Biography Channel.
