Andrew started karate training in Leiston, Suffolk back in February 1988 at the club of Phil Shire 7th Dan, which was then part of Jin Sei Kai Kanazawa Ryu, under chief instructor Paul Perry 8th Dan. After moving to Leeds, Andrew trained at the Red Sun Dojo in Manchester, run originally by Sensei Malc Johnson and now by Sensei Colin Needham. He achieved 1st Dan in 1992, 2nd Dan in 1996 and 3rd Dan in 2001.
From around 1990 Andrew also trained regularly with Sensei Anne Hastings, then the chief instructor of the Mirai Dojo, in time becoming an assistant instructor and grading examiner at the dojo. When Sensei Anne moved away from the area, Andrew was honoured to be asked to take over as instructor of the Mirai Dojo in February 2012. He achieved 4th Dan on 28 June 2015, as a member of the Seishin KyoKai Association recently formed by his original sensei, Phil Shire.
