Pj C. Newton, MA

I was recommended to Big K Mobile by my neighbor. I called Kevin up and he came over in a day or so. When I opened my front door Kevin greeted me with a big smile,was very friendly and courteous. We proceeded to my office and within 25 feet of my pc he said your computer does not have any mechanical problems. I said how can you tell so fast and he told me over time that he has acquired an hear for sounds in a pc, That really impressed me. Kevin was able to take my computer away and bring it back in 2 days, completely overhauled, and running great WOW! Since then I’ve called Kevin on several occasions and he has been able to answer my questions and has not charged me extra. Kevin goes above and beyond for his business which shows me his dedication to his profession. We will continue to use Kevin and also to refer Big K Mobile to our friends.

Kevin has helped me with my private practice law firm computer network for 3-4 years. I used several other firms previously and Big K stands out as the best by far. Kevin is knowledgeable, reliable, responsive, practical and personable. He is always there when I need him and the best recommendation I can give is that I trust him completely. I recommend Big K without any reservations.

Paul Minerich Paul Minerich ESQ. Santa Ana, CA

We have been using Kevin for over 10 years. He is the best most knowledgeable computer tech we have ever had. We have never had a problem he couldn’t fix. He always returns phone calls promptly. He fixes our computers and if necessary orders new ones and sets them up for us. I have recommended him to at least 10 friends who thank me every time that they use him. I recommend him highly.

Gary Miller Placentia, 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!
