      ABSO came to our church’s school and remained flexible to deal with unexpected issues and set up several pieces of technology for us. They even came out afterwards when we were having some additional issues due to third-party equipment interfacing with what they set up. We are grateful for their attentive care for our campus to go above and beyond!

      They were able to troubleshoot the issue to the best of his ability, verify the company warranty policy and checked with me to set up a time that worked to coordinate a call with the manufacturer. He then only brought me into the call when I needed to be, saving me time and frustration. Overall, it was a super pleasant interaction with IT and we were able to get the computer fixed. They other times I've had to reach out they have been helpful as well.

      I've needed IT help a few times over the last few months, and the SugarShot team had all the answers and made quick work of resolving my issues each time — even with my bumbling, not-tech-savvy explanations. It's so nice to have a vendor that I feel confident and comfortable reaching out to for assistance. They're knowledgable and nice — real people doing great work. 10/10!

      When technology throws a wrench into your day, you hope someone like Maribel shows up. We had a few challenges with our office server and without even needing to know the ins and outs of our industry, Maribel from Empowered IT Solutions jumped right in and worked her magic. She was methodical, sharp, and incredibly easy to work with. Within a short time, what felt like a major disruption became a resolved issue, thanks to her calm confidence and technical skill. Highly recommended!!

      Fred Farmer's Review Sourced from Google

      I recently had the pleasure of working with Empowered IT Solutions to set up a new computer, and the experience was absolutely top-notch from start to finish. I want to especially recognize Aaron Hernandez, who assisted me throughout the process. Their knowledge, professionalism, and patience made all the difference. Setting up new technology can sometimes feel overwhelming, but Aaron walked me through every step with clear explanations and a calm, friendly demeanor. They took the time to understand my specific needs, answered all my questions thoroughly, and made sure everything was working perfectly before wrapping up. It’s rare to find someone so technically skilled who also genuinely cares about customer satisfaction. Empowered IT Solutions is lucky to have such a dedicated and capable team member. I’ll definitely be turning to them for future tech support and would recommend them without hesitation to anyone needing reliable, expert IT service.

In one case they hoped on a team meeting with me and helped me explain the tech we're using and how we keep our files secure. I can't say enough good things!!

Sources

DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
