EXCELLENT Based on 43 reviews Posted on Google Mike KolbTrustindex verifies that the original source of the review is Google. Working with David at XPU was a real blessing today. Been struggling to get an API connected for some applications we use and he was the ultimate professional. Highly recommend this team for all of your businesses IT needs!Posted on Google Susan OlivasTrustindex verifies that the original source of the review is Google. I'm incredibly grateful for our IT support team - specifically Aaron and Dhennis! Anytime I have a computer issue - big or small - they respond right away and always get it resolved quickly and efficiently. For example, I work between two properties and couldn't access a share drive I needed to finish a project that morning. I know IT support can get very busy supporting many of our offices; however, Aaron jumped right in, diagnosed the issue, and had everything up and running in no time. Another example is when Dhennis took the time to work on an ongoing Comcast issue with me. He stayed on the phone with Comcast several times and worked with the rep to troubleshoot the issue we were having. I highly recommend them because they consistently provide lightning fast response times, clear communication, and effective solutions. Their professionalism and reliability give our office(s) total peace of mind, knowing our systems are always in good hands. Many thanks!Posted on Google BirgitTrustindex verifies that the original source of the review is Google. The Xperts Unlimited team has been a tremendous support to our entire company for years.

I truly enjoy working with Dhennis and Aaron from Xperts Unlimited. They are consistently friendly, patient, and incredibly supportive—even on days when my questions might fall into the “I probably should’ve known that” category. While I can usually troubleshoot a few things on my own, on those extra challenging, head-scratching days, I know I can reach out and they’ll be ready to help without hesitation (and without judgment!). What really stands out is their professionalism, paired with a great sense of humor—they somehow manage to keep things light and positive, even toward the end of a long day. It definitely makes the whole support experience a lot less stressful and a lot more enjoyable.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
