Matsie did a great job installing our system. He was fast and reliable. He sold us what we needed and not what we didn't. No oversell. He is friendly and courteous and gets the job done. I would recommend him in a second. Thank You.

Matsie is reliable, affordable, dependable and I would recommend him and his business without question. I needed a new computer and he helped me select a new one. When it was ready, he came to my house, set up the new one, migrated over my data and even looked at my girlfriend's laptop while he was there. I have used him in the past for computer issues and he has always been courteous and efficient.

Matsie is the greatest. I had a hard disc crash. The Geek Squad had the computer for a week and didn't recover anything. Matsie took the computer and recovered 99%! He is always responsive, comes to your home or business if he can't fix it remotely. Really knows his business.

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.

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.

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?
