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

My MAC needed cleanup, updating, and stuff I didn’t even know I needed. My guru for the past 20 years was no longer available and Ken was the answer to my prayers. He is knowledgeable, prompt, courteous, and a MAC expert. He fixed problems I knew about and, more importantly, fixed what I didn’t know to ask about. Ken explained what he was doing so that I could understand. He responded promptly to questions I’ve had after his appointment. Ken is on my primary go-to list.

Kevin is very personable, fair, and does a great job. He works quickly but also spends extra time with projects, even when not expected. Kevin seems to go out of his way to be helpful and friendly. I would highly recommend him to anyone.

Cameron Andrews ProActive Physical Therapy Orange, 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

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!

Lynda Witt Proactive Health Solutions Tucson, AZ

I am so glad a friend recommended Big K Mobile Computer Services to me. I have used Kevin for at least 5 years and I trust him completely. He has hooked up my new i Mac, and my new Smart T.V., as well as taken care of any problems I have had with my computer, iPad, and/or iPhone. It is so nice to call or email him to set up an appointment, have him arrive on time and take care of everything. He is very easy to talk to and understand. He never talks down to me and has a great sense of humor. I highly recommend his services. (And he gives senior discounts!) I agree with all the previous 5 star reviews. He’s terrific!

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.

Amy Curtis Laguna Niguel, CA

I would be remiss if I did not take this opportunity to write a comment regarding Kevin and Big K Mobile Computing. On a call for assistance, Kevin promptly and courteously returned my call, and scheduled a convenient appointment. Kevin exhibited exceptional professional and people skills at a reasonable cost. His recommendations were all well thought out and his exemplary technical skills resolved my concerns. Kevin has returned my calls and answered my additional unrelated questions without further charges. Highly recommended for your computer needs.

Arnold Mahler Villa Park, CA

Ken was very professional and knowledgeable.

Yedi Koeshendi Nashua, NH

I have been working with Kevin Harms for three of the six years I have had my MAC computer. Before I was referred to Kevin, who is not even in the same state as I am, I had used many local people. None of these people really were helpful. With Kevin, I e mail him, we set up a phone appointment, he gets in on team viewer and does what I need and he is always reasonable with his charges. I have recommended him when someone needs a MAC guy because I do not think there is any one better!

Marilyn Day Tucson, AZ

I have been utilizing Kevin’s computer services for several years. He is responsive, reliable, and reasonable. Two thumbs up for Big K!!

David Carlisle Whittier, CA

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

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.
