"I was totally awestruck by Mike's professionalism, knowledge and honesty. He was able to reassure me that my used computer is in tip top shape and has more memory then I even imagined. He was able to remotely get into my computer to check it out since he is in Arizona and I am in Oklahoma. Normally I would not have allowed this-but thanks to Mikes many tremendous reviews and A Grade I trusted him and do not regret it. In my opinion he deserves an A++! It's been 20 years since I have owned a desktop computer and I'm obviously not tech savvy! Mike did not take advantage of that and was even kind enough to share some info with me free of charge. I have already opened a file (in my filing account with his name on it)! I am making a list of things for him to help me with and will definitely be back in touch with him. I highly recommend Mike's company to anyone looking for an honest, reputable computer repair person."

"My Geek-tech technician fixed a number of issues I was having with my computers, some of which I didn't even know I had. He also made some adjustments to make it easier for me to use my laptops. A big thank you to Albert Johnson for his help!"

"I first contact Goodberg Computer Services to take care of my laptop. At the end, he ended up fixing our internet at home, upgrading our modem, fixing the airport, and even dealing with Time Warner/Spectrum over the phone - which is always a pain, and he did it with no problems; even got us a better deal with them"

"Excellent service from Tech Hero Services! The technician was professional, knowledgeable, and friendly throughout the entire process. He took the time to troubleshoot the issue, explain everything clearly, and make sure everything was working properly before finishing. The service was efficient, thorough, and reasonably priced. It's refreshing to find someone who is honest, reliable, and genuinely cares about customer satisfaction. I highly recommend Tech Hero Services to anyone needing computer repairs or technical support. Definitely a five-star experience!"

Small jobs welcome

"Very knowledgeable. My OC crashed and my recovery key had not been attached to my microsoft account. He recovered my LocKey and restored my OS. He also upgraded my mechanical hard drive, which was old and causing the problems I was having, to a solid state drive. He also upgraded my ram to keep up with everything and cloned my old hard drive to my new one. While he was here he also reconnected my ring cameras. Yes he is Ring certified and diagnosed my problem with my outside camera systems to a bad monitor. I had an extra flat screen and he installed that also. One service call three jobs. Very versatile guy. Very personable. I will use him again and recommend him to my friends."
