I’ve been proudly serving Tucson and the surrounding areas since 2010, helping customers get the most out of their technology. I service PCs, laptops, all-in-ones, and custom-built computers — and my latest addition, Ring Camera installations.
Whatever your issue may be, my goal is to get you up and running as quickly as possible. That’s why I’m available six days a week, with flexible hours and, in many cases, same-day service.
The best part of my job is seeing the relief and joy on a customer’s face when their computer is brought back to life and performing just like it did the day it came out of the box. That moment never gets old and is what keeps me passionate about what I do.

Larry came out to my house to fix my computer and he did an excellent job. He was friendly and curtious. He not only fixed my computer he explained what had happend and what I should do on a weekly basis to maintain my computers performance.

Larry is awesome! I had a tricky computer issue which required some additional time to diagnose. He took his time to fully investigate and troubleshoot anything and everything he could think of. He also made sure to give me regular updates on what was happening and that I fully understood before moving on to the next step. I highly recommend him for any issue you may experience, big or small!

Larry did an exceptional job on my computer which was a mess and brought it back to better than new condition. He taught me several things along the way and I couldn't be more thankful for all his hard work. He is very dedicated and worth his weight in gold! If I ever have any problems in the future, I will most certainly be calling Larry!

Larry was very professional and informative. He answered all my questions in a way I could understand and never broke a sweat.
Not only was he able to fix my computer but it runs faster now than it did when I bought it. Its really quite amazing.
He is the real deal and I would strongly recommend him.
