Sean is widely acknowledged as being one of the finest performers and writers on the UK comedy circuit. Swapping a career in 1989 as a professional snooker player, Sean quickly established himself as a regular at all the top clubs, later securing himself Time Out's Comedian of the Year.

Sean has remained in high demand as a 'solid' as well as exciting act and was a leading member of the Comedy Store's sharp-witted topical show, The Cutting Edge until its end in 2020.

He has performed all over the world including war zones such as Afghanistan where he was entertaining the troops. Sean has made five appearances at the Montreal Comedy Festival and other festival appearances include Melbourne, New Zealand, Kilkenny, Edinburgh, Singapore, South Africa and Manchester. He has also worked extensively in the US.

In 2010 Sean played himself in Ben Miller's directorial film debut, Huge.
