Great service Once again Rob delivered on service. A week before Christmas I didn't think I had a chance of a service call but Rob had one of his trusty "Nimble Nerds" come to me for a same day service. Chris was personable and competent and solved our computer problem .. which was not really a computer problem but operator error. However, Chris did resolve some other issues while he was here and it was no problem for him. Fortunately I don't have the need to call on Nimble Nerds too often but when I do I know the issue will be resolved. Great service Rob - thanks. Susan BakerPosted on Google![]()

Such a great service! Rob is very knowledgeable, but he knows how to explain things really well to tech-illiterate people 😅. He is not only an amazing tech-head, he is also super lovely (which is so needed when someone is coming into your home or place of work). Thanks for always sorting my tech needs, whether in person, or remotely 🙏💜
