What customers say

I operate a home business that relies entirely on my computer and Mark has helped me many times when I had trouble with it. He is the most knowledgeable person I know when it comes to office machines and how they operate. He is always prompt and efficient, and I highly recommend him.

Mark is a very knowledgeable IT Professional. I have consulted with him on a number of issues and he's proved to be detail oriented, thorough, and solution minded. Most importantly, he's a man of integrity whom you can count on to be there when you need him. I think he would be a great addition to any company.

Mark has always been available when I have computer issues. I own my own business and cannot afford to have any down time with computer issues. Mark always responds immediately and takes care of the problems in a timely and efficient manner. I have recommended his services to my colleagues, family and neighbors. He is the ONLY one we contact when I need help with my computer.
