A brand & web studio

About

From Adelaide to the world, we build creative experiences that help ambitious brands achieve more.


Great organisations deserve to reach their potential.

That belief sits behind everything we do. Our clients come to us because they want to lead their field, grow their influence, tell a clearer brand story, or simply build a brand that feels more like them.

Getting attention shouldn’t rely on gimmicks or AI slop. We’re Argon, after all—not Jargon. It starts with knowing what matters, then expressing your values in a way that makes people care.

Jason Lehman

Studio Director

With over two decades of experience in the creative industry, Jason’s passion for growing brands led him to launch Argon.

With a wide range of technical and creative talents, Jason’s ability is matched by his outside-of-the-box-and-into-the-stratosphere imagination. Where he gets some of his ideas, nobody knows.

Fuelled by coffee—some might say too much coffee—Jason stays awake long enough to spend time with his family, play video games, watch movies and immerse himself in the latest technology.

George Atsalis

General Manager & Creative Strategy

With a 20+ year career spanning multiple industries, business functions and scale, George brings a strategic understanding to creative services – helping Argon and its customers reach their business goals.

Because he enjoys spreadsheets and measuring data, it means you will see him just as at home in a P&L statement as he is in a brand strategy workshop. As tragic as that is, it does have some commercial advantages.

As General Manager, George oversees Argon’s growth and operations; keeping commercial performance and creative output pulling in the same direction. All the while ensuring team performance in Creative Strategy earns the right outcomes for Argon clients.

In his spare time, George can usually be found in his woodworking shop – turning raw lumber into back pain and eventually furniture – or defending his vinyl collection to anyone who suggests it is an inferior format.

Carlo Mezzini

Creative Director

Carlo is a design-focused Creative Director with 20 years of experience across brand, digital, advertising and creative communications. He brings a strategic and hands-on approach to creative direction, combining big-picture thinking with a strong eye for design, detail and execution.

With experience working across a broad range of industries and brands, Carlo specialises in developing creative ideas that are purposeful, relevant, and built to connect with their intended audience. He works closely with clients and creative teams to define clear creative direction, challenge thinking and turn strategy into work that delivers meaningful results.

As a creative leader, Carlo has a practical, can-do approach. He’s just as comfortable setting the creative vision as he is getting on the tools when the work needs to get done. He believes in good ideas, good people and not taking yourself too seriously. For Carlo, the priority is always the work — solving the problem, pushing the idea and making sure the finished result is something everyone can be proud of.

Sandy Lehman

Technical Director

Few things grind Sandy’s gears more than seeing a messy, poorly coded website.

Indeed, with an extensive background in website development, Sandy’s experience and deep-rooted understanding of coding see her playing an integral role in the technical development of Argon’s website projects. Her appetite for clean code and nicely styled and functional websites is matched by an attention to detail that also assists her to accurately scope out projects and budgets for clients.

In her downtime, Sandy enjoys baking tasty treats, watching anime and spending time with her two young children and family.

Sam Lehman

Head of Brand & Story

As a storyteller at heart with a big imagination, Sam is all about helping clients get their message right so they can grow their brand and achieve success.

With a knack for brand strategy and content creation, his diverse career has included work as a copywriter, lawyer and film blogger. He can often be found working with his dog Ripley by his side, and spends what spare time he can find with his family or writing commercial fiction.

Jamie Stefanidis

Web Manager

With over two decades of web experience across London and Adelaide, Jamie has been a core pillar of Argon since 2007.

While the rest of the crew designs and builds, Jamie is the guardian of the finish line and beyond. He’s responsible for flawless site launches, ironclad security hardening, server infrastructure, and lightning-fast client support. In short: when something needs to work, scale, or get sorted yesterday, Jamie is the person everyone turns to.

At home, his uptime is tested daily by his two young kids, though he still manages to find time for AFL, basketball, and the occasional gaming session.

Katrina Ritchie

Relationship Manager

Graduating with a degree in graphic design, Katrina has spent more than two decades in the creative industry, building a wealth of experience and well-honed talent for getting stuff done. As the all-important link between clients and our team across websites and graphic design projects, she keeps communication flowing, expectations clear and projects moving smoothly from start to finish.

Beyond Argon, Katrina devotes herself to her family and enjoys the quieter things in life – getting lost in a good book, pottering in the garden and making the most of time outdoors.

Sam Chadwick

Relationship Manager

With over 15 years of IT experience, Sam brings technical expertise and a patient, friendly approach to managing web projects and supporting clients with domain and website hosting and support.

Outside work, he enjoys camping with his family and a bit of friendly competition over board games.

Josh West

Senior Designer

Michael Vozzo

Senior Web Developer

Michael is a Senior Web Developer at Argon, where he turns our brand and design work into websites that are fast, accessible, and easy for clients to manage.

 

With more than 15 years in web development, he’s worked on everything from small business sites to eCommerce stores and intranets, and has mentored other developers along the way.

 

At Argon, Michael works across custom WordPress development, ACF Pro and Gutenberg blocks, along with technical SEO, Core Web Vitals optimisation, and accessibility. He cares about the details most people never see: clean code, quick load times, and websites that work for everyone.

 

Outside work, you’ll find him with his family, travelling, tinkering with side projects, or checking out the latest cars.

Our history

One thing hasn’t changed.
We do the right thing.

Argon was built around one simple principle: do the right thing.

It’s shaped the way we’ve grown, the minds we’ve brought into the studio, and the relationships we’ve cultivated along the way. From small businesses to global organisations, we’ve always believed good work comes from being invested in the people we work with.

It all started in 2006 as a small ‘Design, Print & Web’ business in a makeshift mezzanine above an industrial warehouse in Adelaide’s Chinatown. A move to nearby Halifax Street and the acquisition of two specialist agencies followed, bringing new faces and new capabilities.

Over the years, we’ve added strategy, copywriting, identity, motion, and video to the mix, while building dedicated teams for print management, hosting, maintenance, and support. Some services came and went, but the best people and ideas stayed, helping shape Argon into the broader creative studio it is today.

While the tools, team, and projects might’ve changed over time, the principle of doing the right thing hasn’t. Low staff turnover, ISO accreditation, and long-standing client relationships reflect a business built to last—combining creative thinking with the technical support and reliability organisations need beyond launch day.


Trusted by local and global brands who value strategic thinking and rock-solid support.

We’re an Adelaide creative agency working with clients across Australia and overseas. Our work is delivered under an ISO 9001:2015 accredited Quality Management System.

We work with charities, not-for-profits, allied health practices, the METS sector, energy and resources, education providers, manufacturers, defence suppliers, trades businesses, and growing SMEs across Australia.

“Kidsafe SA partnered with Argon to deliver our federal road safety project – a first for our organisation and a significant undertaking through two years of work. From our initial briefing to national rollout, their team was professional, collaborative, and fantastic to work with. We felt like they were invested in our project as much as we were, and their outstanding support continued after launch. We’ve since partnered with Argon again and wouldn’t hesitate to recommend them.”
