A Customer’s Computer, phone, iPad or printer issues are easily resolved by each of the employees, I have had the opportunity to work with. Just take it to them or call for instructions if you questing it could be a scam or simple fix. House calls are usually an option if needed. The employees are Knowledgable, interested in your issue, teach as they resolve it and skilled as computer techs. Alpha Omega is a great asset to our community. Please visit them when you need some friendly assistance. My computer was hacked also, It was cleared with safe guards added to prevent further issues in that regard. They are experts at what they do!

I've used their services for several years. They seem ti know what they're doing, don't pressure you to buy this and that. And they're friendly and patient with those who aren't terribly electronics-savvy. Will come to your place if you need them, too.

Alpha Omega computers did a fantastic job for me! I was building my own high end gaming PC when I ran into some problems with the wiring and such as it was my first build. I took my pc in and they were greeting and was happy to take on the job. My technician was Trevor and him and all the guys were great. They even gave me pointers and tip for the rest of my build and great advice. I will be going back to them again soon as they are hands down the best in this area. Thanks alpha Omega
