Barry was great. I was having issues with my screens (3) not working. With a few adjustments I was back up and running. Will be using him again in a couple of weeks to help me set up my new system.

It’s hard to know even where to start describing the standard of Ramiro's attentive service. The IT world is broken beyond belief: lots of snake oil peddlers who don't listen and don't care, and who are only in it to bill as many hours as possible. Lots of them have no idea what they're doing in the first place: I had three separate other professionals come and look at my computer issue prior to Ramiro. All three went down rabbit holes that were completely off base: when Ramiro walked in, I explained to him their theories as to what was wrong, and in 30 seconds he had immediately identified that those were not the issues at all, and what the issue was. He came to my home in the late evening as soon as he saw my texts asking for help (my computer was needed badly for a time-sensitive affair at work): 9:30 p.m. he showed up and worked diligently and expertly on my issue. He took my computer and returned it good as new the next day. The cost was 1/3rd of what it easily could have been and 1/10th of what I would have happily paid for the service (raise your prices Ramiro, trust me).
For those of us who lack the time to become experts in computers ourselves, and so we need qualified help and sage counsel when these devices don't perform properly, Ramiro is like a lighthouse in the storm. Compared the other techs who didn't listen, guessed around, and missed the mark, he's in a completely different category of quality and service.
Ramiro didn't just repair my computer, he repaired my standard of expectations as to what IT assistance can and should be. Will never use anyone else as long he's still in the business.

Hey Tim,
Wow, I just read your review, and I’m honestly blown away by your kind words! Thank you so much for taking the time to share your experience. It really means a lot to me.
I’m super glad I could help you out with your computer troubles. I know how frustrating tech issues can be (I’ve been there!), so I always try to get things sorted as quickly and efficiently as possible. Hearing that I was able to turn your tech nightmare around and save the day (especially in the nick of time for your work thing) is just awesome.
Seriously though, it's clients like you that make my job so rewarding. Knowing that I’ve changed your expectations for IT support? That's the best compliment I could ever receive. And don't worry, I’m not going anywhere – I'll be here for any future tech headaches you might have.
Thanks again, Tim, for your trust and for such an awesome review. If you ever need anything, you know where to find me.
Best,
Ramiro

Ramrio was great. Showed up on time and listened to what the problem was. He then explained how he would fix and went to work. In a short time - all of my computers, printers, and network were talking again. Great work.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Our pricing is transparent and flexible depending on your needs. We offer flat rates for common services, hourly rates for more complex support, and project-based pricing for full-service IT or marketing work. We do not charge hidden fees, and you'll always get a clear estimate before we begin. Discounts may be available for first-time clients, bundled services, or recurring support plans.
What is your typical process for working with a new customer?
We start by listening—whether through a quick call, message, or form—to understand your needs. Once we’ve confirmed the scope, we provide an estimate and timeline. After approval, we schedule service or begin the project. We stay in communication throughout and follow up after to make sure everything meets your expectations. For ongoing clients, we also offer monthly check-ins and support.
What education and/or training do you have that relates to your work?
I hold an Associate Degree in Computer and Network Administration, and I’ve completed specialized training in IT support, network configuration, and cybersecurity. Beyond formal education, I’ve spent over two decades hands-on in the field—building secure networks, solving complex tech issues, and adapting to evolving systems and software.
