"John has been looking after my MacBook Pro computers for many years. His commitment to customer service is exceptional! He is always thinking about how he can save my business money with my Macbook Pros. Apple product servicing can be very expense and time consuming to fix at other repair shops but John always gives me great advice and prompt service."

"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 very knowledgeable and is incredibly helpful. I can highly recommend him. Please use him for all your computer needs!!!"

"I called John and had my computer fixed that day. Within 5 minutes he had it up and running. I previously took it to another place and they were unable to fix it or retrieve the data off of it. I am so thankful I was referred to John! I would never take my computer to anyone else."

"I am a teacher and my computer broke down the week my report cards are due and of the week of my school play with everything in my computer. It was a definite emergency and John came to my rescue!! He came in on a Sunday of Father's Day weekend to help me change out a new hard drive. He does not charge you unless he knows what's going on and how to fix it. I am so thankful for everything that John did for me. I definitely recommend!"

"Jon has helped me out more today than any other company has in the past 2 weeks after my laptop completely gave out. Most places I went to gave me no information and simply just wanted my money. Jon seems like he cares! He's easy to communicate to and seems 100 percent genuine. The type of person who will go out of their way to get you what you need. I'd suggest going to JTG computer repair if you want someone who wants to help and who can help!"

"John, repaired all of my computer's in my business, he was knowledgeable, and quick."

"John was quick to help and locate my 50,000 plus pictures that were on an old hard drive in a Memory Manager Program and transfer them ALL to my new(er) computer into the new version of (M.M.) called Historian. I am SO grateful. Fast, reliable, friendly service with a fair price. Thanks again John and staff!"

"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"

"John was recommended to me by my sister. She told me that he would be able to fix our computer and speed up our Mac so we could optimize its use for another several years. We have a 2009 Mac Book Pro. John took a look at it and immediately came up with a recommendation. John also understood that it would be difficult to be without our computer for a number of days so he had it back to us within 24 hours. John is extremely professional, knowledgeable and accessible. Also, his prices were very reasonable and affordable. All of which, I really appreciated it. I highly recommend JTG computers!"

"John was able to fix my liquid damaged laptop within an hour, and offered great service and affordable prices."

"Amazing service !! John is such a nice guy and very honest and will do his possible to repair your computer at the lowest price and quickest time he can. I’m really happy I found him ... I’ll never go anywhere else!"

"John is one with the computer. Most guys need to Google the fix. John has it all in his head."

"What a great repair shop, reliable, quick and cheap on pricing. Great customer service, 100% would recommend. Did a amazing job on my 2012 MacBook pro"

"John has been my webmaster and computer tech for the past 15 years. I'm delighted to give John a 5 out of 5 on his business sense, business manners and computer repair ability. I highly recommend John."

"brought my computer in today and was blown away by the pricing and quality of service. john gave me quote and stuck to it even though he ran into more than expected. i dropped my computer off at 3pm and was home back online by 6pm. id recommend him to anyone, 5 star plus rating"

""Go to JTG Systems." That is the first sentence that comes out of my mouth when someone in the Niagara Region asks me who to bring their computer to when they have a problem. After accidentally putting RAM in my computer the wrong way after trying to upgrade it, I went to JTG Systems and within ten minutes the problem was fixed and I was good to go. The service is incredibly fast, you can expect your unit to be fixed around a day or two on average. John is extremely knowledgeable about computers and an all around nice guy in general. If someone gave me a computer and said that everybody they went to couldn't figure it out, I would simply tell them that they haven't went to John. That's how much faith I have in him."

"Absolutely great service, good price and very quick repair, definitely recommend!!!"

"John helped me with my laptop, he installed an SSD and ensured that the warranty was upheld on after the fact service. I would recommend to friends and family."

"if i could give more than 5 stars i would!! John was a pleasure to work with in fixing my computer, negotiated a good price for the fix with the proper components i needed and all of it was done in less than an hour in the shop. honestly cant say enough about how convenient and easy it was as well as was just nice to have some good conversation in regards to information i needed to do with building a computer. would recommend to anyone needing to get their computers or laptops fixed or anyone looking to get a refurbished piece of equipment!!"

"Computer was slow and wouldn't load properly. JTG Systems had it diagnosed and up and running in about 30 minutes. Full diagnostic followed and haven't had a problem since."

"Took two laptops in for different issues. Computer one was completed and working perfectly on return. Computer two took another trip but they were very professional and second trip was free of charge and they helped find additional solutions. Thanks very much."

"Gave in my desktop computer and got it fixed quickly for a decent price. Also professional and easy going staff helped out. Best guy I've been to"

"Good and reliable service! Wouldn't recommend any other computer repair place!"
