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.

The owner, Alex, is a nice dude, but a poor communicator. My laptop was having crashes, and I…read moredropped it off in early June for troubleshooting/diagnosis. I called after several weeks and he promised he'd have the problem diagnosed within the next couple days and call me back. Several additional weeks went by and I called again with the same response, and then once more a few weeks later- a total of 2 months of wait time without any progress or evidence that anything was done at all. I eventually gave up and got my laptop back myself to look at. Googling my error messages indicated that my RAM was faulty, and after replacing the RAM (a 15-minute procedure), my laptop works fine. It took me ~30 minutes of total active time to troubleshoot and solve this problem that I had previously waited 2 months for the owner to fix. I'd guess that Alex was overcommitted with fixing other machines to focus on mine, which is fine if he told me a realistic estimate (i.e. "I'm really busy right now, but check back in a month and I'll give you an update). Instead I got drip-fed inaccurate timeline estimates. Overall, I find it difficult to reccomend going to this business to get your problem fixed unless you have a really easy software issue to diagnose/fix on the spot.

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.

I normally don't write reviews on here, but I felt that others should know about my experience. To…read morestart off, I should mention I am not an expert in computers & technology, but at the same time I am not a novice either. I have fixed and modded computer components & have built PC's plenty of times on my own. First time I went here, I went to get my 15" Macbook Pro Retina laptop screen fixed, an easy repair. I went here because I was too busy to do it myself. Sorin (lead repair tech) advised to replace my broken screen with a used screen to reduce the repair cost. I said thats sounds good and proceeded. When I got the repair back, the screen itself was dirty and the metal lid had tape and residue on it. I understand that the replacement part was a used piece, but he couldn't spend 5 minutes wiping it down and making it look presentable? This was a $500+ repair. At the end of the day, it isn't a big deal, but the reason I mention this is because it is relevant for my next experience with him and this business. My $7500 custom build PC that I had built, suddenly no longer could boot up, POST or enter BIOS. Sorin offered a diagnostics test for $80. I agreed as I needed to confirm which of my parts was malfunctioning so that I could process a warranty claim with the brand. On the phone, I had asked him if I should bring manuals - he said no. I bring in my PC and I tell him I will be right back as I left my power cable for the PSU in my car. He admentently says I don't need to bring it in (without even looking at my PC). Okay fine...I'm not going to argue with a "professional". I also asked if he would like to be provided a list of the parts in my PC to help him troubleshoot more efficiently. He said nope, no need. I drive back home. Next day, I get a call from him and he tells me that he did not realize my PSU (Corsair AX1600i) has a different plug and that he requires me to bring in my power cable. Great. Now I have to drive all the way back to the store when this could have been avoided if he took 30 seconds to look at my PSU when I first came in. I get a call from him later and explains the tests he ran. I should note that he said he was not fully able to test my CPU (3970x), GPU (RTX 3090), or motherboard as their shop does not have the parts needed to run a in-depth diagnostics test on higher end computer components. *This is why I originally told him if he would like a components list of my build when I first came in.* Basically I paid $80 dollars for a rudimentary diagnostic test that was not comprehensive at all in my opinion, as the CPU, GPU, and motherboard are the most important components of a computer. Fine, I guess this is the best I can get for an $80 dollar diagnostic test. I promptly ask him to put my PC back together so that I can pick it up. When I arrive at the store, he hands me my PC back and he said was not able to get the front facing fan on the CPU cooler mounted properly onto the heatsink. Um...okay...your business is called "PRO - Technology Professionals", but you can't even mount a basic CPU cooler onto the motherboard? I also noticed when he put back my GPU, he did not plug back in the power cables for it. And he also reseated my memory sticks incorrectly (pic included).He clearly put no effort in putting my PC back together. Do you not take pride in your work? Completely sloppy. This kind of leaves a sour taste in my mouth, but again, not a big deal to me, so I bring it back home. When I get back home to inspect my PC closer, I noticed the reason he could not mount the front facing fan on the CPU cooler is because it was the incorrect fan. My CPU cooler (be QUIET! DARK ROCK PRO TR4) has 2 fans that need to be mounted onto its heatsink. I don't understand how he could have messed this up because the two fans are both different sizes and only one of them fits on the inside. Instead, it's clear he forcefully jammed the other fan into it as it is basically impossible for it slide it in otherwise. It is astonishing he did not try to look for the manual online, or bother to call me to confirm how to correctly put the CPU cooler back to together. This was not a AIO or custom loop liquid cooling system... This was a simple cooler with two fans. The only way I could pull out the fan was to break the rubber gasket on the heatsinks - thereby damaging both my fan and heatsink. I call him and address my complaints and was ultimately met with an attitude. He tells me I need to bring my computer back to the store so that he can remove the fan. I refuse as I am not going drive a third time back and told him there is no way to remove the fan without damaging the cooler. I am normally a easy to work with guy and I am usually empathic to certain situations. I didn't even ask for a full refund and was compensated a $20 dollar refund. That doesn't even begin to cover my $90 CPU cooler. To have my $7500+ dollar PC disrespected like this is completely unacceptable. Avoid this place.
