Our Story

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.

GZD

Through the years.

October 2001

Starting Again, West End

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.

2004

Growing Into Donkin Street
Demand had outgrown the original space, and GZD moved to Donkin Street. This marked the shift from a small restart to a steadily growing business with an expanding team and client base.

2006

Vasco Goncalves Joins as Director
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.

2007

Newmarket Road & a Strategic Decision
GZD relocated to Newmarket Road, Newmarket and made a defining strategic choice: to put a major focus on the health industry, particularly pharmacies and medical practices, alongside continued support for general business clients. From this point forward, GZD shaped itself around the needs of community pharmacies, general practices and medical specialists, and businesses that need stable, responsive IT and cloud services.

2008

Medical Director Partnership
GZD became a certified Medical Director partner, formalising our relationship with one of Australia's leading clinical software providers.

2009

Investing in Our Own Data Centre
Rather than relying solely on third-party hosting, GZD invested in its own data centre infrastructure — allowing us to deliver higher reliability and performance, strengthen security and compliance for sensitive health and business data, and respond faster when issues arise.

2010

Leader Systems Partnership
GZD entered a formal partnership with Leader Systems, expanding our capability to support clients with specialist hardware and technology solutions.

2018

Stat Health & Breeze Connect Partnerships
GZD formalised partnerships with Stat Health and Breeze Connect, strengthening our healthcare IT and communications capabilities.

2019

Acronis Partnership
GZD became an Acronis Advanced Certified partner, reinforcing our commitment to enterprise-grade backup and cyber protection for clients.

2020

Z Software Partnership & Move to Stafford
GZD added Z Software to our pharmacy IT partnership network. In the same year, we purchased and relocated to 33 Hayward Street, Stafford — our long-term home, with the space and infrastructure to support continued growth.

Today

36 Staff, 700+ Clients, Australia-Wide
GZD now supports independent pharmacies, general practices, medical specialists, large Medicare centres operating across multiple locations, and general business clients throughout Australia. Our team of 36 works every day to keep critical systems running reliably, deliver secure and well-managed infrastructure and cloud services, and build long-term relationships based on responsiveness, accountability, and trust.

The GZD Difference

We're Part of Your Team, Not Just Your Supplier

A lot of IT providers will fix the ticket and move on. We work differently.

We see ourselves as a genuine extension of our clients' teams:

Invested in their success, familiar with their environment, and committed for the long term.

We Tailor Solutions to Your Needs

We don't apply a one-size-fits-all approach. Every client has different systems, different workflows, and different challenges. We take the time to understand yours and build solutions around them.

Fast, Senior-Level Response

When critical issues arise, they are handled quickly by experienced engineers, not queued endlessly or passed between support tiers. Critical response time is 15 minutes.

Clear Roles and Smooth Processes

We manage the full scope of IT projects and ongoing support with clear responsibilities at every stage, so nothing falls through the cracks and you're never left wondering who's handling what.

Security and Compliance Built In

Rather than treating security as an add-on, it's embedded into our standard managed service model and aligned with ASD Essential 8 guidelines.

Local Presence, National Reach

We provide responsive onsite support across Brisbane and surrounding regions, backed by strong remote capability and partner networks throughout Australia.

Our Values

We want our clients to feel genuinely served, not just technically supported.

That means effective communication, clear responsibilities, and IT solutions that really work for them and contribute positively to their business success rather than adding complexity to it.

These are the values that guide how we work:

Accountability

We take full ownership of our clients' IT environments. When something affects your operations, we don't deflect responsibility to vendors or third parties — we see it through to resolution and communicate clearly at every stage.

Security First

Security is built into every decision we make, particularly in highly regulated environments like healthcare and pharmacy. From access controls to backups and cyber protection, we prioritise safeguarding sensitive data and maintaining compliance at all times.

Proactivity

Our focus is on preventing issues before they disrupt your business. This means proactive monitoring, regular system health checks, structured patching schedules, and regular meetings to discuss potential pitfalls or upcoming upgrades, before they become problems.

Our People Matter

We greatly value our staff and suppliers. We invest in personal and professional development, hold ourselves to high standards, and attract staff who share our passion for great client outcomes. We understand that good management systems and resources will support our business. We work as a team to gain from the combined strengths of one another. When our team thrives, our clients feel it.
