"This is the second time John has updated and serviced my computer. I had trouble with my outdated printer (not supported by manufacturer) and with his computer expertise he got my printer up and running again. I highly recommend John, and also appreciate his patience with me due to my lack of computer knowledge. Thanks John :)"

"Met with John last week due to my wife MacBook 12" logic board failing. He took the time to look over it for many hours and determined the only repair was to replace it. He didn't charge me a single dollar for his time and if I decide to go through with the repair I will definitely be bringing it back to him. very knowledgeable and friendly!"

"Incredibly helpful with solving my computer problem! Answered all of my questions, and completed all the work that needed to be done in a timely manner. John gives great pricing, and actually repairs with good quality parts that won't break immediately."

"Wow, what can I say about the service I've received. Took my computer into them with a power issue that 3 different computer stores could not figure out and spent over $100 for basically no fix. JTG Systems took one look at the previous work done and found out the issue was the computer case! Had it fixed within a day. Fantastic service and friendly staff. Definitely going to be using JTG Systems for all future servicing! No questions about it!"

"Excellent service, simple seamless how it should be, I worked with John and he was very helpful. Would 100% go back there for any future computer issues I may have."

"Spoke with John at JTG systems. He is extremely professional and knowledgeable. He is a straight shooter and will tell you his honest opinion. I highly recommend this company for all your computer needs !"

"Brought in a team computer and got same day service - not only was my computer repaired and files backed up, the system was finely tuned to make it go faster than what it was before. These guys are definitely above the other shops in this area (Thorold, Welland, St. Catharines, Niagara Falls, St Davids, Pelham, Port Colborne)"

"John did an excellent job on my computer. I was so worried that I had lost all my files but he brought them back and installed a new hard drive. Thank you, Johanna"

"I called for Onsite Service, my computer was running like a snail, and there were things popping up all the time, hard to use. JTG Systems / John came to my house for a very reasonable price, fixed all of my issues and gave me a 90 day onsite warranty. highly recommend to friends and family. thanks so much."

"I was visiting my family for a few days but was flying out to Edmonton right after and needed 2 laptops and 1 portable harddrive to be faster and cleaned up JTG called me which the issues and told me the fix which was beyond reasonable and the price was unbeatable! Everything was ready to be picked up that same day! Amazing! Going to be using them again for sure! Thank you!"

"I HIGHLY recommend JTG Systems! John was extremely helpful in assuring me that my old Mac was an affordable, fairly simple fix. When another local computer repair business told me it was a lost cause, I almost gave up on it. He replaced my hard drive, added more RAM, updated it and explained everything he was doing in a way that I (a not so tech-savvy person) could understand. In just a couple hours, my computer was ready to be picked up and he even lent me a cable to connect my old hard drive to the computer, and move over old files. I'll definitely be calling JTG for any of my computer needs from now on. Thanks again, John !"

"Very helpful. Appreciated the extra effort and time it took to resolve my Mac laptop issues. Recommended!"

"So fast, so friendly, John went above and beyond with both service and support to make sure my laptops were running efficiently and to my specifications. And at a third of the price staples quoted me for a lesser service. Thank you!!! We won't go anywhere else."

"all in one works 5X faster thanks, also helped me get rid of malware infecting the computer and other security problems computer is way faster. and they fixed it the same day like the ad said. I dropped it off at noon and was called before 5 to pickup! wow."

"John is amazing at what he does! If you're in need of a computer repair company, website design, or SEO company you're in the right place. John has helped my company with all three services. My company website needed some design updates for the SEO service I hired him for. Not long later my PC wasn't working properly and I was so thankful to find out he could fix my computer as well. Great all in one computer services!! Thank you again John!"

"Brought in my desktop today after lunch. It was unresponsive and would not boot up. John and his friendly team were able to diagnose and repair the same day! Reasonable rates and very quick service."

"JTG systems, John Gallie is the most reliable honest computer guy you can get to fix your laptop or desktop! Who can beat same-day computer repair? And if you're not sure if you can trust leaving your personal information in someone else's hands you can 100% trust John! He has a police clearance, took police foundations in college, served in the military, and volunteers for crime stoppers. I highly highly recommend him! Two thumbs up! :-)"
