There are two kinds of IT people, the ones who leave you more confused than when you started, and…read morethe ones who quietly solve the problem and get you back to running your business. Working with Matt was exactly that. He was prompt, professional, and refreshingly easy to work with. No unnecessary jargon, no drama, just honest expertise and a genuine commitment to getting the job done right. As a small business owner, having someone reliable to call when technology gets in the way is invaluable. If you're looking for an IT professional who knows his craft, communicates well, and delivers on his promises, I highly recommend him. Good people are hard to find. Great IT people are even harder.

I can't say enough great things about Matt. He absolutely saved me this week…read more My Lenovo laptop completely failed to boot after a graphics driver cleanup utility corrupted the Windows boot configuration and recovery environment. The system was stuck in a recovery loop, BitLocker was triggered, and Windows wouldn't load or even reliably enter repair mode. Multiple shops I called said it would take several days just to diagnose the issue. Matt turned it around in essentially one day. He was able to manually access the system, unlock BitLocker, repair the corrupted boot configuration, rebuild the necessary Windows files, and get the machine fully operational again -- without wiping my data. That was critical, as I had local files that weren't backed up to the cloud. Beyond the technical expertise, what impressed me most was: * Clear communication * Fast turnaround * Extremely reasonable pricing * No upselling, no unnecessary "reinstall everything" approach He diagnosed the real issue quickly and fixed it correctly the first time. If you're an independent contractor who depends on your machine daily, or you run a small to mid-sized business and need reliable, competent IT support, Matt is exactly who you want on your side. Look no further. Highly, highly recommend.

I had a poorly configured home network with lots of connected devices, several computers, and network attached storage. A couple of computers had stopped talking to each other and passwords were messed up. I couldn't get the answers or solutions I needed from websites. I was frustrated. I had never used a consultant but Yelp directed me to Nestech Computers. I worked with Shawn of Nestech for an hour and a half. He remoted in to both my computers at the same time to see, test, diagnose, and adjust settings to success. He was knowledgeable and thorough in addressing my problems. He also cared about my whole network to add some extra network adjustments to improve its operation. I would use Nestech again. They left me with network nirvana, devices that all work together nicely.

I went to Angelo's for my Apple laptop that got damaged from a fall. The screen was severely…read moredamaged and we all know how expensive it can get to repair just the screen of an Apple laptop itself. I was initially looking at a good $500 repair from most places and knew it was hopeless. But luckily I stumbled upon Angelo's via Google search and to my surprise he fixed my laptop screen like it was brand new all within half the price which other places offered. Angelo was also very humble and kind as he unfortunately sustained an injury prior to that week and I knew my laptop was going to be fixed in at least 2 weeks due to his injury. But Angelo didn't waste any time and somehow fixed my laptop screen with just one hand in a matter of a few days. Though I hope I don't come across anymore computer related issues, I'll gladly go to Angelo for any computer issues I may come across. I highly recommend everyone to go to Angelo for your computer repair, you won't regret it!

Mark Lebowitz is a caring and intuitive IT tech…read more I was starting to panic after 2 weeks of no wifi in my home. Comcast had run new cable from the pole but when the problem continued, it became my fault, not theirs. I scrambled to find an independent IT contractor and after a few failed attempts, called Lebowitz IT Services. He ran a "ping test" diagnosis on my modem (which I lease from Comcast) and while the signal was strong, there were inconsistencies that could have been enough to interrupt my service. I then insisted Comcast send another tech and sure enough, that was the problem. They actually had to "dumb-down" my modem to an older model that was more tolerant of the inconstancies. I can certainly recommend Mark for any home business IT work.

Update: this week my 18-year-old son called the office in hopes of getting more upgrades. This time…read moreour experience was quite a bit different: the person who spoke to him on the telephone was quite short, very disinterested in hearing about our problem, and quoted us $295 for a single hour of diagnostic. The original build we did with this company included them adding cooling fans. Unfortunately the cooling fans were improperly installed. They were all connected directly to the power supply instead of the motherboard, so they run 100% of the time. Because of this improper build, one of the fans is already gone out.Even though my son willing to pay for the service, $295 is simply unacceptable. Not to mention the fact that my son was treated disrespectfully on the telephone. I can no longer recommend this location and will be looking for other computer services in the area. Really a shame.
