At Johnson Health Tech Australia when we refer to ‘Team Matrix’ we are referring to all of those people that help us perform to the best of our ability, with the dedication and commitment needed to continually strive for excellence. Hence ‘Team Matrix’ is the term we like to use to refer to our staff, our partners and our endorsers. It is through the hard work of all of these people that JHTA provides assurance in backing the ‘Team Matrix’ pledge of total support and excellence.



John Mullen, National Commercial Sales Manager

Since beginning his time with Matrix as a Commercial Sales Executive in 2010 John has consistently outdone himself year after year leading to his steady growth within the company. John manages all major commercial accounts with which JHTA deal, this role has seen John form strong and profitable business relationships with a number of notable gym chains that we hope to work with well into the future.
His ability to establish and maintain relationships with key accounts Australia and New Zealand wide ensure his clients and their business colleagues turn to him continually for new sales, equipment upgrades, gym refurbishments, advice, recommendations and direction.

Anthony Larsen, Commercial Sales Executive – QLD, NT & South Pacific Islands

Anthony may be a newcomer to the Matrix team, but he is by no means new to the industry having 15 years of experience under his belt. Anthony started out his fitness career as a personal trainer/massage therapist; he then made the move into managing health clubs and eventually into selling commercial fitness equipment. This hands-on experience in a number of aspects within the industry leaves him in great stead to do what he loves--getting great outcomes for his clients and their facilities.
Over the past ten years of his sales career, Anthony has placed a lot of focus on building lasting relationships with a number of types of clients such as big and small chain clubs, hotels, corporate, defence and education.

TECHNICIANS – Service/Delivery & Installation

Daryl Rowley, Senior Technician

Daryl is a qualified electronics technician with a cabling licence and 26 years of experience in technical and electronic fields. Daryl is driven by curiosity to find out how things work and how all the individual elements fit together in each piece of equipment. More recently, Daryl has worked for JHTA for more than five years gaining valuable experience with Matrix commercial fitness equipment.

As standard at JHTA, Daryl holds a portable appliance testing licence, D&R certificate of competency and a full fork lift licence as well as a heavy rigid truck license. This allows him to work on any job site, including those in the construction phase, and lets him be hands on at every stage of the installation.

“Great install experience we had as Daryl stayed back and put in considerable effort and advice to get the install perfect. The team work in particular between Daryl and Jamie to accommodate and change our order to get the club and install perfect in the last few days was also appreciated. I want to make clear this kind of service is what prompted us to then increase our order with a few more strength and studio pieces”

— Steve Mion, Bulleen Health and Fitness

David Nicholls, Senior Technician – QLD

David has been working within the fitness industry for almost 10 years now, over two years of which have been with us at Matrix. David has not come from the vast mechanical background of some of our other technicians but more than makes up for it in passion, know-how and a keen mechanical interest. He is a very skilled and reliable technician with a penchant for diagnostics over replacements, and is an absolute asset to the team. As standard within Queensland David also holds a Restricted Electrical Licence.

Before entering the fitness industry David worked within heavy mechanics operation as well as maintaining heavy earth moving equipment, experience which has assisted with his smooth transition into this industry.


Geoff Johnson, Technician – Melbourne

After qualifying as a motor mechanic, Geoff worked in the trade for ten years servicing, repairing and adjusting cars of all shapes and sizes. Needing a change, Geoff decided to become a personal trainer and qualified as a fitness instructor. His vast experience in the fitness industry, skills and ability with machinery and practical tasks made him the perfect candidate for becoming an equipment technician.

A UK native, Geoff worked as a technician in his homeland for almost 8 years with two different suppliers. Geoff immigrated to Australia in 2003 and continued to work with various fitness equipment supply companies. He has a vast knowledge of different brands and equipment and has been a great asset to JHTA since joining the team in April 2010. Geoff can quickly and easily identify what is causing a fault on a machine, and his experience with motors, consoles and moving parts mean the problem is resolved and the equipment back up and running in no time.

“[Geoff has] personally followed up on [repairs] every time. Not once have I had to ring up or email hurry ups like I have had to for every other company.”

— Stephen Mion, Bulleen Health and Fitness

“We recently had our elliptical machine in our home serviced by Geoff Johnson. We were very impressed with Geoff’s service. He demonstrated pride in his work and in his company and we would like to compliment him on his effort and professionalism.”
