I have been a monthly subscriber for years and I have always been impressed. They are always very professional and patient. Any computer issue I have ever had has been resolved in record time.
Ron Whitehead
My laptop had become completely dysfunctional with multiple disruptive viruses. This occurred because I had allowed protective software to lapse. I had a deadline to meet. I hired Geeks on Site on a plan that was reasonably priced. The Geeks on Site tech got started remotely. Within an hour and a half she had eliminated all the problems and put in place new protective software. My laptop had been returned to complete functionality. I had thought the computer was beyond repair when I first discovered the problem. With Geeks on Site, not so!! I have high praise for this company!!

My frustration with my large LG television is finally over. The nice technician who came, solved all of my problems with the apps, explained how my smart TV worked, and gave me instructions on how to find my favorite programs.
