Coolmaster NT was started in July of 2012 by Owner/Tech John Johnson, a Territorian born and bred, with over 15 years of experience in the industry.

John was given the push he needed to build Coolmaster NT from the ground up, after losing his position with the company he worked for, due to them going into liquidation. Subsequently he worked hard and fast to turn a full time passion, to supply his skills and expertise into the market, into the business that is is today.
