Ryan's Well Foundation

Kollaard Associates is an engineering firm in Kemptville. For the past 16 years, we have purchased all of our computer related equipment from Sigma Computers. Our staff uses a variety of "computer hungry" drawing and design software packages. Sigma has always carefully paired new hardware with our unique software requirements. In 2009, we relocated to a new building. Sigma provided network services and server solutions, working after hours to ensure that the transfer went smoothly. We are a very satisfied customer.

We have found Sigma Computer Systems to have the best computer repair pricing and service of those we have tried. We also appreciate the quick personal response in carrying out the work required.

My name is Mark Muzerie. I own and operate a small business as a Network Cabling Technician contracted to GOC. I have resided in the Kemptville area for quite some time and have relied on Sigma Computer Systems for my personal and business PC needs. They have always been expedient, reliable, knowledgeable and more than fair servicing, renewing and managing my system requirements. Please do not hesitate to attain their services. They are very professional and good people.

Sincerely, Mark Muzerie

We run a busy Foot and Ankle Clinic which transitioned to a new self contained office 9 years ago. At that time we transitioned to a custom paperless electronic charting and booking system. Sigma Computer Systems designed and installed a secure office network and worked with the Software company to ensure a seamless transition to the e charting system. Since that time Sigma has been our go to company for hardware repairs and upgrades and the secure storage of data. They are always available and understand our needs and requirements and implements them in a friendly, timely and cost effective manner. I would always suggest Sigma Computers over any ‘Box Store’ for hardware and software requirements.

I've had the pleasure of having Sigma Computer Systems build two very excellent Digital Audio Workstations for me... Sigma's work is meticulous and their scope of knowledge is quite extensive. I highly recommend anyone looking for a new computer system to make their first and last stop Sigma Computer Systems.... you certainly won't get Sigma's level of service & expertise from Staples or Future Shop!

Bruce "Bear" Valeriani, Blue Bear Sound

When we went looking for local I.T. support we approached Sigma Computer Systems. We have found Sigma to be both very knowledgeable and accommodating. Turn around time is always very good, even when we pop in unannounced. We have also purchased equipment from Sigma and have found them to be very competitive. I have recommended Sigma in the past and will continue to do so.

I have been dealing with Sigma computers for 7 yrs. I have found this business to be knowledgeable and very friendly. I would recommend stopping by and discussing any computer problem that might be plaguing you. If you should need your data backed up or you have purchased a new computer and require your data to be transferred there is no problem with expertise and confidentiality. If your data needs to be recovered from a failed system the knowledge and experience of Sigma computers will find it and back it up.

I began using Sigma Computers over 10 years ago and chose them to handle our conversion to new technology because I wanted someone I could trust. Sigma worked diligently to build our new computers and was, and still is, there for the questions that arise after the sale, something that is sorely lacking with big box stores. I found Sigma Computers knowledgeable, patient and their response time is quick. I highly recommend them for all your business and gaming computer needs.
