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

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

Our company has been working with Kevin for around six years now and it’s tough to put into words how appreciative and impressed we have been with his work. I’m not kidding when I say we’ve hired and fired no less than 5+ external computer technicians before finding Kevin… he was a godsend for our company. Kevin has helped with everything in our office ranging from computer issues to server setup and he’s always been nothing but professional. Kevin also has to been the only computer technician in America that has everyone in the office smiling the second he walks in until the time he walks out the door. He’s genuinely a great guy and knows what he’s doing; he’s upfront and truly does look out for the client whereas many in this field are simply looking to take advantage. I’m done gushing now… give him a call and you won’t turn back. Kev is the man!

Ted Slaughter RealSource Partners Newport Beach, CA

I don’t know where I’d be without Kevin.  He sets up and solves all my computer and printer problems, plus he set up my new televisions and netflex.  Most of all, he is dependable, his prices are reasonable and he is a gentlemen.  I would and have recommended him to others.

Marie Kontos Newport Beach, CA

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

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.

Amy Curtis Laguna Niguel, CA

He was knowledgeable and VERY helpful. I received excellent and prompt service. Any time I had trouble, I would receive a response within an hour. If he could not fix it over the phone. He would be there the next day to fix the problem.

Thank you for your over the top work!

Ian Waugh Corona, CA

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

Big K, Kevin is great!
I’ve been using his services for at least fifteen years. He is friendly and courteous. He knows everything tech. He is knowledgeable about all kinds of hardware and software. If you know a lot about tech, or not so much, like me, he’s your guy. I’ve never had a problem he couldn’t solve.

James Matthews Buena Park, CA

Connie Papple 20th Century Air Anaheim, 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

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

Kevin at Big K has been setting up and servicing my computer, printer, cell and tv for years. He is very professional, knowledgeable and reasonable. I would recommend his services to anyone.

Linda Oster Anaheim, CA

A friend recommended Kevin to us and we in turn recommended him to other friends for many reasons. He is very conscientious in returning voice mail and email messages, makes every effort to schedule a convenient appointment time (How much easier is it to have him come to your residence or business instead of carrying your computer somewhere?), is very prompt, personable and professional. We appreciate his patience in working with our 14-year-old grandson and with us 75-year-old grandparents. His people skills and his ability to explain and teach are awesome! He goes out of his way to assist in any way he can.

Roger Duthoy Yorba Linda, CA

This is the greatest company ever! They give 100% always! They go beyond customer service and expertise. Kevin has been my guru for many years and has never not been unable to fix my problem. I would never call anyone else, why would I when I have the best? I have sent many clients to him and will continue to do so. If I could do a higher rating than five, I would go all the way up!!
