Sheldon is hailed as a leading expert in gang culture and is both an advisor to the Home Office and New Scotland Yard on gang culture and violence, and to Trident which is a specialist unit dealing with black-on-black gun related crime. Sheldon regularly sits in on the Home Office round table discussions and has contributed to the Home Office ‘Ending Gang Violence’ Strategy (2011). He also currently provides strategic and tactical advice to the London Boroughs of Barking and Dagenham and Newham on gang-related activity, and informs on cross-border issues for the London Boroughs of Waltham Forest and Redbridge.

His journey began in 1988 when he met the late Bernie Grant, former Labour MP for Tottenham. Grant saw potential in Sheldon and offered to mentor him. In the subsequent years Sheldon used his new found focus as he travelled to areas of the United States where he met civil rights acticist Jesse Jackson, and Jamaica to learn all he could about gang and drug related crime and violence and how they tackle it. Inspired by Bernie Grant, his own family and everything that he had learnt he dedicated his life to helping the disillusioned and disinfranchised young people in society reach their potential.  

A regular and outspoken contributor to television, radio and newspaper, Sheldon is a motivational speaker and visionary. He is contacted weekly from across the globe by individuals, businesses and government representatives who seek expert advice and support on an issue which is blighting communities and is failing to be successfully addressed by politicians and criminologists alike. In addition to his pioneering work with gangs, Sheldon also obtained a Certificate and Diploma in Management and holds a BA (Hons) in Marketing and Statistics. Sheldon has been married to his wife Michelle for 17 years and has 4 children.
