Over two decades of connecting people and place through wayfinding and visual language

“People interact with our work every day, they just don’t know it. You can’t walk 100 metres in a capital city in Australia or New Zealand without coming across a piece of signage or wayfinding that Diadem hasn’t touched,” says Diadem’s CEO and managing director, Dominic Russo.

With a vast project portfolio spanning the retail, transport, hospitality, corporate and financial spheres, Diadem harnesses the power of visual language in transforming brand vision into a built reality. This is witnessed in everything from marrying architectural form with brand strategy, to installing iconic sky signs.

Founders Adrian Calleri, John Saddington and Dominic Russo first came together in 2000 with the vision of building a business that would one day hold an international reputation as experts in corporate signage and wayfinding.

Today, the company has an annual turnover of $32 million and manages an annual project portfolio of over $40 million. To date, Diadem’s projects under management have totaled over $800 million. Diadem is now a team of over 80 strategic, creative and technical specialists across six offices in Melbourne, Sydney, Brisbane, Adelaide, Auckland and Hong Kong.

Beyond signage and wayfinding management and procurement, the company has expertise in multi-disciplinary design, including communication, industrial and engineering, procurement support and project management.

The Diadem team is currently working with Commonwealth Bank, NAB, Toyota, Australia Post, Ford, European Garage (EG), Melbourne Park Precinct, Brisbane’s Queen’s Wharf, NSW Health, Commercial Bay Precinct and Kiwi Properties in Auckland, and HSBC in Hong Kong, among other clients.
