Mark Thomas Sargent was born on the 31st December 1969 in Cuckfield Hospital, West Sussex.  Brought up in Haywards Heath he attended St Wilfrids Cof E primary school before moving on to Warden Park Comprehensive and Haywards Heath Sixth Form College.

In 1988 he commenced studying Electrical and Electronic Engineering at what was then Kingston Polytechnic, and after completing the course (and running out of money!!) he returned to Sussex.  After a number of temping jobs he took up the offer of a post in the NHS as a Trainee Neurophysiological Measurement Technician on the 6th January 1993, based at Hurstwood Park Neurological Centre, Haywards Heath.

Eleven years on Mark still remains at the same department, albeit with the revised job title of Chief Clinical Neurophysiologist.

Aswell as his clinical work, Mark is an active trade unionist and is branch secretary for UNISON Mid Sussex Health

Outside of his NHS employment Mark enjoys playing (although not particularly well) golf and online computer games (if you get killed on "Call of Duty" by CSS_Technohead you now know who the culprit is!).  His main hobby has always been music, but with a natural inability for singing or playing an instrument he has instead turned to DJing and runs a successful mobile disco company  called Energy Entertainment.
