From a Small Office in West End to a Purpose-Owned Building in Stafford
GZD's story starts further back than Brisbane. Founder Craig Theisen originally built and grew a business under the GZD name in South Africa before eventually relocating to Australia.
In November 2001, he started again from scratch in Brisbane: One technician, a small office on Melbourne Street, West End, and a clear set of values about what good IT support should look like. More than 25 years later, those values still drive everything we do.
Through the years.
GZD re-founded in Brisbane by Craig Theisen, operating from Melbourne Street, West End. From day one, the focus was practical and client-driven: keeping systems running, solving problems quickly, and becoming a reliable technology partner rather than just another IT supplier.
Vasco Goncalves partnered with Craig Theisen, bringing strong operational capability and disciplined leadership to the business. His focus on execution and process continues to drive consistent service standards today.
GZD entered a formal partnership with Leader Systems, expanding our capability to support clients with specialist hardware and technology solutions.
Craig Symons joined GZD from South Africa in 2015, bringing a strong customer service background, leadership experience, and a passion for building long-term client relationships. His customer-first approach has helped strengthen client satisfaction, communication, and support processes across the business.
GZD was recognised as one of Kyocera's leading resellers in 2024, reflecting the team's commitment to delivering high-quality print, document management, and business technology solutions. This achievement reinforces GZD's position as a trusted technology partner for businesses across Queensland and Australia.
In 2024, GZD rebuilt its data centre infrastructure to meet continued business growth and increasing customer demand. The new environment significantly increased capacity, improved performance, enhanced redundancy, and strengthened security. This positions GZD to support customers at scale while providing a platform for future growth and innovation.
