See what our clients have to say about Big K Computers:

I stumbled upon Kevin many years ago when our office needed an expert for our computer systems. From the start, he was reliable, accessible, knowledgeable, professional and personable. We always looked forward to working with him. He was always so patient and kind. I have also employed him to work on my home computers. He is trustworthy, honest and responsible. I don’t know what I would do without him! He is a very special person. I highly recommend him!

Kevin in the past two years has been very helpful to me in resolving numerous hardware and software issues on my PC and printing device. He gives his customer good response time and is on time for his appointments. He is effective in diagnosing problems therefore doesn’t waste customer’s time.. He also offers warranty period.
For those reasons, I choose Kevin among other vendors to service my PC and accessories.

Kevin is a master mind when it comes to computers and any wiring services for cable, phone, etc. I have known him for 10 yrs. or more. He always shows up when he promises. No problem or challenge goes unsolved. He works quickly so you really get your money’s worth, and is always fair with his billing. He usually gives you an idea of how long a project should take so there’s no surprise at the end. He walks you through each step of the way to make sure you know how to get back up and running once he leaves. Whether you are setting up a new computer, monitor, or printer, have some odd error message, need to transfer data or set up new programs, set up a network, connect a second printer to fax or scan, or even experience a major crash, Kevin should be first on your list to call. He also will help set up an efficient and best value means of virus protection or data backup. I highly recommend Big K mobile for all your personal or business needs.

Jim Nashua, New Hampshire

Kevin came highly recommended to me over 5 years ago by another firm and he is simply terrific. I work from home, on several computers, with multiple operating systems and have exceptionally high document volume and trust Kevin 1,000% to keep everything running smoothly. And when I have a technical issue (usually operator error) or need any kind of computer related assistance, Kevin has always provided tremendous customer service! It is also important Kevin gets right down to business when he arrives – you get more than you pay for! You will not be disappointed!

Tamara Baker 20th Century Air Anaheim, CA

I’ve known Kevin for about eight years. He’s polite and courteous. Kevin knows his job well. He makes house calls which is convenient instead of you having to to take your computer to and office. I’ve had him work on my MAC’s and help me get my granddaughters’ PC’s set up and running and even added an Anti-Virus on both PC’s. I have to agree with a review I just read that he keeps everyone smiling while he is at my home working on the computers. If you have a problem with getting a computer loaded correctly or need stuff transferred off your old computer to an external hard drive give Kevin a call. I highly recommend him.

Alice McDonald Cypress, CA

I want to first start off by letting everyone know how awesome Kevin is as a computer tech. I found him probably around 4 years ago, when my one of my computers at my business was giving me problems. He is so efficient on how he handles his arrival times, its so refreshing to deal with someone who does exactly what they say they will do. He is really upbeat and funny while always working and getting the job done quickly. He even will let you call him on a small problem that he thinks he can walk you through at no charge. I totally recommend Kevin to anyone needing mobile computer service at a fair price. Thanks Kevin.

Linda Ganci Jump O Rama Buena Park, CA

Over the past few weeks I have been having problems with certain apps crashing on my computer for no reason whatsoever. I had several different services look into fixing my computer but each had no success. I was reffered to Ken from a friend and I am extremely happy with his service. He went the extra mile that no other company did, and fixed every issue I had with my computer. He was extremely friendly throughout the process and explained everything in detail so that I knew exactly what he fixed. I know down the road if I ever have problems with my computer, Big K Mobile Computer Services will be my first call.

Anthony Gallo

We have been working with Kevin for several years. He successfully set-up the wireless networks in our office and home offices and connected all of our (many!) mobile devices. Whenever we run into computer trouble, he is only a phone call or text away. He is always reliable, on-time and guarantees his work. He is an excellent multi-tasker and able to work on several devices and issues at a time. Having reliable networking and mobile services is critical to our small business and Kevin helps to keep us up and running. He is very personable and a pleasure to work with!
