Jodi Bennett

Louis and his team go full out to give you exceptional service. When I first engaged louis at the end of last year. He went above and beyond to find a solution for me. We were struggling being a small business to find a service that would fit our needs. Being from an IT background i had to let go the reigns, so I could focus on my business. Louis and his team allowed me to do so. Good work Catalyst, throughly recommend any business that are going to the next stage of their growth.

Peter Morris

Cataylst has been taking care of our medium sized business with outstanding customer service for a while now. The type of customer service where everyone is happy to talk, explain things to those learning, can deal with changing priorities, explain options rather than trying to upsell everything, schedules pickup's/drop offs quickly and fast remote fixes. This level of customer service & attitude is so rare these days.

Nick Avery

Louis and his team have provided efficient and professional support for many years. Their response time and resolution of problems in a friendly and efficient manner is impressive. We have complete confidence in their ability to provide high level computer support.

Catalyst computers recently installed a new sever for our small business.

Throughout the process we found Louis and his team to be very professional and good value for money. More importantly they completed the work on the weekend to reduce disruption to our business.

I would highly recommend Catalyst Computers to any small business needing IT support.

We are small business and needed a computer expert. We are so very happy that we contacted Louis from Catalyst. From the outset he was helpful, extremely knowledgeable and efficient. Easy to relate to as well !!

Julia Taylor

I have been working with Catalyst computers for at least 4 years now with their staffing requirements for the growing team. So I know they have a GREAT team of support staff. And I really love their efficient approach without the fluff and BS - their job is to make sure your IT systems are working...and that's what they do best.

Kim Acworth

Sensational support and service. Called with and urgent inquiry at 7 am on a Sunday morning and by that afternoon they were on the job. Louis was at my office installing a new server until 2 am the next morning.
He has discounted my monthly fixed price support fee by 30%. No matter what happens now. I know its not going to cost me more that my monthly support fee.
