John R. – Manufacturing (SME) Leamington, ON

“We have found Mark to be knowledgeable, friendly, and efficient. Mark has already offered us good advice on our IT, and fixed our immediate issues.”

Ryan C. – Automobile Dealerships (SME) Almonte, ON,

“The most important aspect of my service experience was that Nick did not treat me like a dummy. He was helpful, answered any questions I had, and kept me in the loop of what he was doing. Excellent manners…very respectful, that is very important. At the end, he gave me some instructions on how to accomplish what I needed should the issue arise again. The charge, which was reasonable, was well spent. Thank you again Nick!”
