About Us

Two Wellingtonian techie mates had a vision – to provide simply the best in internet connectivity and Data Centre services, without customers having to sit on hold to a help desk for hours.


Those two mates – Dion and Mike – turned that vision into reality. Xtreme Networks was launched in 2000 by Dion. Mike joined full time in 2003.  


From humble beginnings in Dion’s house, Xtreme Networks has rapidly grown to a premium facility in Thorndon, Wellington.  From IT integrators to law firms, Xtreme Networks provides a trusted service to hundreds of businesses across New Zealand.

Xtreme Networks is 100% New Zealand owned and operated. And, after 20 years in operation, they are proud to say that their vision is still intact: Xtreme Networks provides seamless internet connectivity and secure Data Centre services (without any painful helpdesk woes). Seamless. Secure. No worries.

We take the pain away from dealing with issues so our customers can get on with their work day.

I wanted the freedom of working for myself. I also wanted to provide top quality service – I like making our clients happy.

I started in the security industry – managing the computer side of security and maintaining two networks (one for the security company and one for the alarm monitoring business). With this security background and interest in tech, I became inspired to work for myself and launched Xtreme Network in 2000 from the spare room of my house (much to my wife’s delight).

My dog and my family. I like the simple things such as walking my dog in the bush with my family.

Our customers can rely on us. If there is a problem, we are onto it immediately and fix it.

I find the technical side of the business really exciting. I like solving problems. I value good service so that’s what I wanted to provide. Working for ourselves is great too.

After 8 years as an auto electrician where, working for a small team and privately owned business you quickly get an idea of how to deliver good customer service. I changed career paths and worked briefly in access control, then at a share broking company running end of day procedures and backups on their computer systems.  From there I moved through the internet banking and business banking helpdesks of a major trading bank. I joined Xtreme Networks full time in 2003.

In addition to technology, mountain biking and music are my other passions.
