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

Ken was very professional and knowledgeable.

Yedi Koeshendi Nashua, NH

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!

Jill DeCriscio Alliance Outreach LLC Orange, CA

Kevin is the best. He has been servicing my computer needs for years and I can’t say enough about his knowledge of what I need.

You can’t go wrong with Kevin.

Amy Curtis Laguna Niguel, CA

I am convinced that Mr. Kevin Harms and his Big K Mobile Computer Services company are both as good as it gets when I have needed computer services during these last 8 years that we have used his services in my dental office. We have 8 computer stations all interconnecting and of course issues come up unexpectedly.

We call Kevin. He communicates back right away. Whether it has been an emergency bug infection, or a computer needs replacement, or even the server needed totally upgrading, he appears as promised, always with a positive attitude, Kevin has done it very smoothly every time! He is a very well informed technician at computer structure. He is also a whiz at working with Microsoft Office and QuickBooks to make our computing such a headache-free routine in our office!

May you continue to prosper in your wonderful company!!

Al Navas Sunwest Dental Long Beach, CA

Ken was extremely efficient and friendly. He told me everything I needed to know about the new software I had purchased. I would highly recommend him for anyone looking for an electronics expert. He completed the job flawlessly and in a timely manner. Thanks again Ken. My girlfriend and I were extremely impressed with your professionalism.

Nashua, NH

Kevin at Big K Computers was recommended to me by a friend and it is the best recommendation that I have received. Kevin is extremely knowledgeable in the tech world, friendly and takes the time to explain whatever your needs are in a way that is easy to understand. He also guarantees his work for 30 days. So if the problem continues, he will come back out and take care of it. The last time he came out, I had a problem with my computer — he helped me with that. Then he helped me with my cell phone. Then he helped me with my new smart TV. He knows it all. I have his number programed on my phone so I can reach him quickly, if I need to. You won’t be sorry if you call Kevin Harms.

Belinda Levin Tustin, CA

Terrific person and service. Thoughtful advice, helpful explanations, prompt, generous with his time, goes out of his way to come to our house when needed.

Steven V. Lexington, MA

Big K Mobile Computer is the best. Kevin is extremely knowledgeable and stands behind his services. He will never suggest anything for ones computer that isn’t needed. Kevin is so professional and extremely easy to get hold of and work with. He shares what he is doing in non computer lingo which is great for those who feel lost in the tech world! I would without hesitation recommend Big K to anyone who needs a “computer doctor”.

Joan Ash Stanton, CA

Hiring Big K Computers for my small business was the best decision I made. I met him 14 years ago and appreciate his OUTSTANDING customer service and technological expertise. I have a very small business and rely on his knowledge to help me find the answers I need that also fits my budget. Kevin has taken the time to understand my business needs and makes recommendations accordingly; not over-selling unnecessary hardware or software. I trust him fully and recommend him OFTEN to friends and family.

Brenda Witt Proactive Health Solutions Costa Mesa, CA

Kevin at Big K computers has been my “Go To” guy for years. Kevin is very professional, easy to communicate with and always on time. He makes life easy with working around your schedule. Kevin has helped me out with my Mac’s, windows desk top and phones. He always explains (in plain English, not the tech talk I don’t understand) what he is doing and what needs to happen to fix it. He offers solutions and does it in a timely manner. I recommend Kevin to all my friends and neighbors.

Cory Munro Anaheim Hills, CA

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!

Donna Metcalfe Vice President, Teamsters Union Local 952 Orange, CA

Kevin at Big K is the best. In ten years of service, he’s always quick to respond, friendly and trustworthy. ¬†When he leaves, I know my computer’s fixed with no issues.

Tanya Hazelton Yorba Linda, CA

As a couple of “less than tech-savvy” seniors, we have relied upon Kevin for several years and are happy to tell all that they can’t go wrong with Kevin! He is friendly, responsive, has reasonable rates, goes out of his way to make sure we understand what the problem is, and is very thoughtful in suggesting solutions and giving options, knowing we are on a tight budget. He is a unique combination of a smart, technically proficient professional combined with a “you feel a friend is visiting” kind of demeanor. He truly deserves five stars!

Linda Wolff Santa Ana, CA

For over ten years Kevin has been my “go to” guy in taking care of any of my computer problems. He has fixed the problems when needed and set up new computers when needed. I have found him to be reliable, knowledgeable, always on time and always just a telephone call away for help.
I feel so fortunate to have someone that I can call on over the years instead of having to rely on strangers from problem to problem, never the same person twice.
I do strongly recommend Kevin and I have done so many times and each time he has not let them or me down.
