Mark 'Crowley' Russell - Senior Correspondent

Crowley (known to his mum as Mark) began diving in 2000 in Sharm El Sheikh, before quitting a 10-year IT career and moving to Thailand to take his PADI IDC in 2005. He moved from Thailand to Australia and Curaçao before returning to Sharm as an instructor in 2009. He managed a Nusa Lembongan dive centre between 2013-14 before hanging up his instructor booties and returning to the UK. Crowley started writing a regular column for DIVE in 2010, and now looks after DIVE's daily online content and writes regular features for the print magazine. In his spare time, Crowley is an enthusiastic guitar player, devoted motorcyclist, dedicated gamer, and door-opening expert for two cats.
