Customer Testimonials

Dear Advanced Computer Group,

Thank you for your prompt and quality computer service. You responded so swiftly and you solved all my problems. It's a comfort to know I can get some quality service when I need it. I will recommend you highly; Keep up the good work.

Sophisticated knowledge...


I just want to take a minute to commend you for the fine work you did recently at my home. I'm like a guy who doesn't like to stop and ask for directions. Fortunately, my wife finally made the phone call to ask for your help in resolving issues with our home PC. You not only succeeded in restoring our Dell PC to "better-than-new" condition, but you enabled me to connect my laptop with my home printer, 'wirelessly', for the first time. My commercial real estate business is already benefiting from your expertise.

I would enthusiastically recommend your company and your services to anyone that desires a 'house-call" at their home or business, in order to resolve any, computer or hi-tech issues. I am pleased to say that I found your service both convenient and efficient; at a price that was reasonable, and fair. Your sophisticated knowledge combined with your friendly and trustworthy personality make it very easy for me to confidently refer you to others.

Very Professional...

I work for the family business and was having a tough time setting up a wireless network and wireless print server for the office. I had contacted Advanced Computer Group. Within a few minutes they had already diagnosed the problem and began working to correct the issue. They were very professional and extremely informative when it came to network security. Their pricing was very fair, and I would not hesitate to call them again for any other computer issues. I would highly recommend Advanced Computer Group for all computer and networking issues.

Courteous and Considerate ...

Dear Advanced Computer Group:

I could not let another day lapse without sending you a letter to express my appreciation for the computer services you rendered. You were not only courteous, but considerate, calling me to confirm the appointed time for the service call.

Above all, I am very grateful for the professional work you rendered which enables me to use my computer efficiently. As I mentioned, the computer is one of my key "lifelines."

In today's busy and complex world, it is rare to find highly-qualified workers. It is obvious you love your work, respect yourself and your profession, and therefore, respect others and theirs. Rest assured I will be spreading the good word about you.

A host of thanks.
