"We have been using TJ Microsystems for over 15 years and watched our network expand from one server and a few machines to 6 servers and over 40 machines. We are a business that runs 24/7 and we need IT Support that does the same. The experts at TJ Microsystems have always been available when required and have never let us down."

"We have been using Thomas and the team at TJ Microsystems since 2004 and have become integral to our business needs. In addition to the everyday maintenance they are also there the moment things need fixing and that gives us peace of mind. We don't consider TJ Microsystems to be just another service provider they are part of our team and part of our service offer, because without them we couldn't function."

"Have had nothing but great all round service and advice from TJ and the gang at TJ Microsystems. It’s easy to see why their tagline is ‘your trusted technology partner."

Rowland Percy

"It was difficult to find an IT service provider for our unique business. We’ve worked with TJ Microsystems now for several years and trust their team to meet our IT needs. As a Charity we need to be careful with our funds, we have found TJ Microsystems expertise has saved us thousands of dollars in unwanted downtime and expensive IT failure. Their managed server contract is simply the best IT solution that we’ve utilised and as a result IT system outperforms many systems much larger than ours."

David Jackson

"We have been using TJ Microsystems in our business for several years now and have found that at all times the business and staff have been very professional, accessible, trustworthy and always prompt to act and take care of our IT issues. The latest technology and back-up support service is very important in our business with our computers and booking engine needing to run proficiently 24 hours a day. We appreciate them no end!"
