Randall coming to install our computers and doing all the installation of hardware (or software) makes my life easy. He is also always available to help when I have questions.

Luis is very professional, timely, and helpful. We requested his services again this year because we found him to be exceptional last year.

Randall was able to navigate me from having a brand new laptop fresh out of the box to having it function as a tool that I will be able to use in my new job, and in ways I have never used a laptop before. I don't know how he did it, but he showed mw how to get into programs I was locked out of, how to log into apps I had no experience with, come up with passwords that opened doors to heretofore unknown apps and programs, how to record case notes by speaking into my laptop microphone and saving myself time otherwise spent "hunting and pecking" (one of those wonderful recommendations that changed my life). He also suggested that I should be asking my new employer to help with the cost of purchasing a new dedicated laptop and having him (my Nerd) come in to help me get set up in preparation for the expectations of my work at the new agency. Randall is also has a great, dry sense of humour that takes a lot of the stress out of a very challenging task, at least for me. I would have been 'way out of my depth and stymied without his help.

Well, he did say my typing amounted to hunting and pecking. No one wants to hear that! Otherwise, I can't criticize anything about the work he did for me!

Give this man an award for putting up with me! I am the least computer-savvy person in the world! Yet he gets through to me!

An unknown person had been attempting to hack into my social media account, credit cards, PayPal and my bank and had also tried to extort money from me by way of email. Randall took quick and decisive action to secure all of these accounts by changing passwords and removing the accounts from password manager on my home page and storing them safely.

Once again, Randall demonstrated his expertise in the field of technology masterfully! He continues to support us with his knowledge, patience, teaching skills and answering our questions in a professional manner. He is a problem solver and explains technology in terms we understand which enables us to proceed when we are on our own. He is always available to answer our questions after the task is completed. Thank you, Randall for your continued professional support and trustworthy character. Randall is a great asset to the company. Don and Liz Mills

We are grateful for Randall’s ongoing support. His humour gets us through the frustrating moments and glitches of technology.

LUIZ is very talented.....smart, patient, great with my suppliers over the phone. Went beyond the call-of-duty. Can't wait to recommend him to my friends.

Just cannot say enough good things about Luiz....hi8ghly skilled, friendly, patient (with a non-technical person like me). Terrific personality, which is very crucial in a 'people business'.

I had told my nerd my problem and he phoned unexectedly on a day when I would not have expected it and solved my problem using the online device. It took only a few minutes and my nerd made sure I could handle it by myself from then on.

As I senior, I was overwhelmed by the set up of a new PC and monitor, plus by the need for a more secure system, including that of my cabled outdoor cameras. A google search on cybersecurity led me to Nerds on Site. And a phone call led me to Luis Feliz. Methodically, Luis proceeded to set up the new, migrate the old data, and secure all systems. He lifted a few months of worry off my shoulders. I am very grateful to him and the entire NOS team..

Luis Feliz is my electronic angel. I will periodically be in touch again. Of course I will recommend NOS.

He is a real pro and always positive in all my interactions with Randall He took the time to explain everything to me. All through the process, he was never rushed.
