Meet John Gallie

Born in May 1985 in St. Catharines, Ontario, John developed a passion for computers at a young age and has been working with them since Windows 95. He attended AK Wigg, Glenn A. Green, E.L. Crossley and Niagara College.
Military Service & Expertise
In 2002, John joined the Department of National Defence / Lincoln and Welland Regiment as a Canadian infantry soldier. During his three-year service, he underwent rigorous training in urban warfare, tactical strategies, and all infantry weapon systems.
