Cameron Andrews ProActive Physical Therapy Orange, 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!

I recommend Big K without any reservations.

Kevin at Big K Computers came highly recommended to me. I had issues with my security software for my business, so when it was time to renew, I had him do a complete diagnostic on my system, and install new security software. I’m glad I did. Here’s why I will always turn to Kevin for anything technology-related:

* His expertise and experience are off-the-charts …not just with computers, but smart devices, TVs, web services, products, etc.
* He shares his knowledge in terms you can understand …and gives you tips + practical advice
* He offers personal service and comes to you to do the work on-site
* He’s very thorough and methodical …but works relatively fast
* He stands by his work and follows-through
* He’s responsive and accessible …I can call, text or email him at any time with a question
* He’s very competitively priced and doesn’t “sell” you on anything …He just gets the job done
* He is easy to work with, keeps you up and running, and you can trust him

I was so satisfied with Kevin’s work that I had him do diagnostics and install security software on all the computers used by my family. I’ve referred him to relatives and friends who have all be very satisfied. So anyone who is in need of top-notch technical support service – Kevin is your guy.

Amy Curtis Laguna Niguel, CA

Big K Mobile Computer Services is my go to for purchasing computers or any computer related issues. Kevin is an all around great guy. Professional, dependable, personable, reasonable AND he can work and talk at the same time! TicToc. When my work computer goes south on me, I send an SOS to Kevin and when he walks through the door my anxiety level goes back to normal, because I know my computer is in good hands and that the issue will be addressed quickly. Big K performs regular maintenance on my work and personal computers, so that really cuts down on issues and fire drills. No better computer than one that doesn’t fight back 🙂 I found Big K years ago through a referral and I couldn’t be more pleased. You will be too!

Debra Munson Pamela M Smith Security Seminars Inc. Whittier, 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

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.

Barbara Morrisey Fullerton, 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

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!
