Born in Coleraine, Northern Ireland in 1959, Tommy was educated at a local grammar school and, equipped with the requisite A levels, moved to Scotland to study medicine at Aberdeen University. He graduated with a degree in politics and sociology – the start of a lifelong interest in politics.
He returned to Scotland in 1993 and established the Stand Comedy Club in 1995, which he started as a hobby and built into a successful business. Tommy lives in Minto Street with his partner Kate and cocker spaniel Henry.
