Customer Testimonials

“He is charming, delightful, knowledgeable, and an all around great guy. He is my IT guy. We discuss everything from computers to our children and grandchildren. He's the best. Why would I go anywhere else?”


We're older people and we get intimidated by computer geeks who come in and say how easy or simple this is. Matsie explains everything in a way that makes sense without making us feel like dummies. He set our system up so the things that we need are right at our finger tips. He even made it easier for my husband, who has some hearing and vision problems. He also has coached me over the phone when we had a small problem. We use a lot of companies through Diamond Certified and we are very happy with MA4.


I felt that they were very personable and helpful. I was having problems with my computer and didn't have a clue what was going on with it. They listened to what I had to say, or at least figured out what I was trying to say, and they were able to solve the problem.
