I was satisfied with TruAdvantage help with a workstation replacement for the company. They transferred all my necessary files to the new laptop. The transfer and setup for the laptop were completed in a timely manner. I am grateful that TruAdvantage was able to help with this project.

I have very good experience with TruAdvantage. I highly recommend them to anyone for their IT needs. I was very happy with my recent experience from Cherish Anarcon. She solved my issue quickly and professionally. Plus, she was very nice about it.

IT Support LA is a great IT company. They are extremely fast and efficient and respond to any questions in a flash regardless of the time. The technical support such as David and Suzanna are quick at resolving an immediate issue that occur. Andrew is also fast to respond to major projects, problems, or responding to advice. They provide additional services to on request and are reasonably good at providing updates on progress of said projects. I would definitely recommend.

Igor is very professional and very helpful. On a recent call he went above and beyond to assist me with my questions and concerns, explained everything thoroughly, answered my questions and provided solutions. I highly recommend Igor and IT Support LA for any business owner looking for IT and cyber security support.

The team at ITLA is fast, efficient, knowledgeable, courteous and very helpful. They understand the needs of our business and are ready to help when we need them, even on the weekends. ITLA has been our IT support for over 5 years, and we consider ourselves so lucky to have them as our IT partner. We can’t run our business with out them!

David Gonzalez from IT Support LA was incredibly helpful and patient in assisting our team with our new printer setup. He guided us step by step, answered all our questions, and made what could have been a stressful process smooth and easy. His professionalism, clear communication, and willingness to go the extra mile made a big difference. Highly recommend working with David!

IT LA took over our law firm’s IT needs a few years ago. This review is LONG overdue. I cannot understate how SMOOTH and EFFICIENT our IT services are at this point. Every problem is immediately addresed via email and Teams, and they are excellent at anticipating our needs. Andrew Schiff in particular has been absolutely amazing. I could not ask for better IT support.

I had the pleasure of working with Denny and Sam at Team Logic, and I can’t say enough about how wonderful they’ve been throughout the entire process. From the moment I reached out for help with my system issues, they both were incredibly patient, understanding, and committed to resolving every single one of my concerns. What truly stood out was their willingness to stay on the phone with me, guiding me step-by-step as I attempted to access my applications. They didn’t rush me at all and made sure everything was successful before hanging up, which gave me such peace of mind. Their patience and attentiveness were remarkable, and they consistently demonstrated a level of professionalism that was truly impressive. On top of their technical expertise, both Denny and Sam have such warm, approachable personalities. It made what could have been a stressful experience feel more like working with friends who genuinely cared about helping me. I highly recommend Denny, Sam, and Team Logic to anyone in need of IT support. Their dedication, expertise, and wonderful customer service made all the difference for me!

All the techs are so friendly and helpful. I recently was helped by Sam, and he was great!!! Great company! Great service!

⭐⭐⭐⭐⭐ **Exceptional IT Support and Outstanding Customer Service** As a Case Manager, I rely heavily on technology to effectively support my clients and complete my daily responsibilities.

Pepe set up my computer, desktop, and printer quickly and efficiently. He was patient throughout the process and took the time to show me how to operate everything. He explained each step clearly, making sure I understood how to use the equipment. I appreciate his professionalism, knowledge, and excellent customer service.

The IT team was very helpful, patient, and knowledgeable. They resolved my issue quickly and provided excellent customer service. Highly recommended!

The Crimson IT team provided excellent support during the recent Microsoft app reconnection issue. They responded quickly to this time-sensitive situation, communicated clearly, and resolved the problem efficiently. Their prompt action minimized disruption and is greatly appreciated.

Outstanding service. Everyone there is very friendly, patient, kind, and calm – which is just what you need when addressing IT issues and/or concerns. They know what they are doing, and very knowledgeable and quick to act. Their responsiveness is also untouchable.

Great, fast customer service. Greatly appreciate there assistance when I most need it. Thank you!

Very timely, kind, and patient! Sometimes dealing with IT can be a pain, but they made this process of onboarding simple and easy!

Relion is simply the best! They are always so reliable and helpful. Thank you so much Brian, Zach, Manny, Toby, Alex, Carlos, Kennan, Dave, and team!! I don’t know what I would do without your support.

Relion is my employer’s IT team and they are fabulous. Every time I need assistance, someone answers my call eager to help! They are very knowledgeable and reliable. I’m especially grateful for their patience when a simple «restart your computer» before calling would have helped. One day I’ll remember to do that 😉

The team at Relion has been amazing! They have managed to keep our office technology up to date and working smoothly. It gives us peace of mind to know at any moment we can reach out to them and get a live person to trouble shoot any issues we have with our office network. We just moved into our new office, and they had us all set up in one day which helped avoid any down time during our busy season. Glad we found them.

I turned to Relion to help me resolve a problem with my email storage folders. Toby Adea was assigned my ticket. He listened to my explanation of the issue, developed an approach to fix it and then proceeded to successfully implement his approach. There were challenges along the way but he hung in there with conviction and reassurance that a fix was well within reach. I would highly recommend him for anyone with computer issues.

As a pediatric reconstructive surgeon, I needed to find an IT company with some expertise in certain aspects of healthcare IT. Though I rarely write reviews, this company is so truly exceptional that I feel compelled to explain why. We actually contacted them initially from a google search that led us to read their reviews, which were overwhelmingly positive. When we first met Brian, he was so knowledgeable and friendly and full of great suggestions for us. Coming off of terrible experiences with our two prior IT companies, Relion seemed very different and obviously excelled in customer service. In these past two years of working with them we have gotten to know most of their employees, who are all incredibly kind, resourceful and always helpful with a positive attitude. On the rare occasions that we have had urgent issues, Relion is so responsive and solves the issue very quickly. I can’t say enough good things about this company…I hope to work with them until the day I retire!

I cannot say enough good things about Relion. As a small business owner, I ran into an email issue that had me completely stuck — other IT providers took one look at my situation and turned their noses up. Not Relion. From the very first conversation, they got me. I’ll be the first to admit I’m a stubborn, set-in-my-ways kind of guy who has zero interest in changing how I do things. Instead of lecturing me or insisting I overhaul my entire setup, they rolled up their sleeves, assessed the situation on my terms, and found a creative workaround that solved the problem completely. That kind of client-first thinking is extraordinarily rare. They didn’t dismiss my problem because it was unconventional or because I wasn’t a Fortune 500 company. They showed up, listened, adapted, and delivered — and they did it with patience and professionalism that I didn’t even know I deserved. If you’re a business who feels like the big IT firms don’t provide the level of service commensurate with what you’re paying them, go to Relion. I’m deeply grateful for their help, and I wouldn’t hesitate for a second to recommend them to anyone.

The Relion team is the best! No matter the problem, big or small or as simple as restarting your computer, they will help you solve it. I’ve worked directly with each member of the team and every one of them is a delight. They are patient, kind, and really know their stuff. After nearly three years working with them, I highly recommend Relion for all of your IT needs. Update: Two months since leaving my initial review, I have worked with Manny countless times on everything from setting up new devices to adding employee access to our company drives. He is always a pleasure to work with and solves any problems quickly and efficiently. Thanks Manny! (And the entire Relion team!)

Our CPA firm has been with Diamond IT for over 14 years beginning with in house support and then transitioning to the Cloud in 2013. They have provided excellent technical & personalized service from day one. The entire staff continues to be professional, knowledgeable & responsive to our needs. We highly recommend their services!

Nick provided prompt support and sought another path for making contact when the primary method wasn’t available. Once the service call was started he was very efficient and courteous. He also clearly wanted to make sure all issues were resolved before ending the call. The Diamond IT remote interface also worked very well. —JD

We use Diamond on an unlimited plan. It’s a little pricey but in this day and age, having an IT pro on-demand is worth the expense. They’ve been pretty responsive every time I have an issue.

always a pleasure to do business with Diamond. From hardware orders to tech support I have seen this company grow as I have been a client for 14 years +…… Their customer service is awesome and I always feel like they truly care about our firm….

Tommy is amazing. I have had multiple visits and he has always provided excellent service. It’s normal for him to go above and beyond to make sure all is working well. Keep up the great service Tommy!

This company is wonderfully professional, quick to respond, and extremely knowledgeable. They took what was an incredibly frustrating problem for me, and made short work of it. I highly recommend Diamond IT for all IT needs

I have had very good experiences with them, they handle all of the IT problems that we cannot solve by ourselves. Tickets are normally solved within the same day.

Excellent service! My ticket was handled within 10 minutes of submission, despite my noting it was not urgent. Thank you, Kenny!

Edwin was very professional, knowledgeable, and showed great patience. My issue was resolved on the first contact.

The team at Advanced Networks is amazing. They have been providing us with IT service for years and their service is always the best. They are very quick to respond to any issues we have and are very knowledge and professional. They have also helped with our office move and the entire project was quick, efficient and seamless. We would not go with anyone else!

For the past 5 years, Advanced Networks has provided high-quality IT services to us, with professional courtesy, respect, and at a reasonable price–compared to other IT companies in the market. The team is super responsive—-and there has never been a 48-hour wait time, nor a 24-hour wait time for the team to respond to a request for service—which is priceless to us! They don’t mind going the extra mile to ensure that everything is always working properly, and they will even answer a call on a weekend to take care of an issue—again, priceless! We continue to be very happy with their high-quality IT expertise, services, products, suggestions/recommendations, and we look forward to our continued business relationship for many years to come. Thank you very much team! Roslyn C. Phillips, CEO ACEBSA – Los Angeles

I cannot say enough good things about Advanced Networks. We switched to them from a global IT company and the difference has been incredible. Issues that hadn’t been fixed for over a year with the prior company were top priority with Advanced Networks and they were resolved immediately. Any and every issue we ever call with seems to be at the top of their list, making it feel like we are their number one client, where in reality we are probably one of their smallest. I love calling and getting a live person. I love that there is a team that knows our setup and can help. Jonathan is my go to person and he’s been beyond amazing. He’s on top of any and every issue I ever bring him. I love how honest he is and responsive.

We have been working with advanced networks for over a year now before that we were using another company for our IT needs but we were not happy with them. I couldn’t be more pleased with the performance of advanced networks. They supply full support, they’re very professional, attentive, and quick to resolve any technical issues that arise. They are a very knowledgeable and experienced team. I would highly recommend advanced networks.

Advanced Networks is really very good. Quite honestly, I was pleasantly surprised at how much our IT spend has normalized. And, on top of that, our company has seen a drastic reduction in the old, recurring IT problems that used to cause us big slowdowns and outright egregious losses in productivity. If you’re in charge of a business and you’re looking for a reliable managed IT services provider in Los Angeles, I strongly recommend contacting these guys and having a chat with them.

Our company has been working with TeamLogic for over three years, and they have been an incredible partner throughout our growth. As a small but rapidly expanding company, having a dependable IT team is critical, and TeamLogic has consistently exceeded our expectations. I want to give special recognition to Arti, Jorge, and Ricki. They are always quick to respond, incredibly knowledgeable, and genuinely invested in helping us succeed. Whether it’s troubleshooting an urgent issue, supporting new initiatives, or helping us scale our IT infrastructure, they approach every challenge with professionalism and expertise. What sets TeamLogic apart is that they don’t just fix problems—they take the time to understand our business and provide solutions that support our long-term goals. Their responsiveness, technical knowledge, and customer service have made a real difference for our team.

Finding a reliable partner for infrastructure and support can be a challenge, but it’s a pleasure to work with Team Logic IT. They provide quick responses that keep operations running smoothly and are incredibly easy to schedule projects with when we need to scale or upgrade. They have a very knowledgeable team that truly understands the complexities of modern IT management.

Our company utilizes Team Logic IT to assist with our day to day and major IT support and I love this team! They are extremely responsive and the partnership we have with them is priceless. We have put so many processes in place to allow for a seamless transaction between our two teams and they are always there for us ready to assist or pivot as needed.

TeamLogic IT has been an outstanding partner for AVANA. Ticket closing times have improved dramatically, and we’re seeing much faster turnaround across day-to-day requests. Just as importantly, their security posture gives us real peace of mind, their filtering blocks about 90% of phishing emails and malicious links, making it rare for any fraud to reach our users. We genuinely appreciate their effort, communication, and reliability, they’ve made it easier for us to work without constant security worries. Strongly recommend TeamLogic IT for responsive support and robust protection.

I appreciate the response of all that have worked with me. They demonstrate a remarkable amount of patience in dealing with us less than tech savvy users.

Super helpful and kind, and Alejandra even gave me steps to help resolve the issues on my own in the future if needed. Very appreciative!

I really appreciate the support from Alejandra and George. They’re always quick to respond, incredibly helpful, and approach everything with a calm and reassuring attitude. No matter how simple my question might be, they never make me feel uncomfortable for asking – it truly makes a difference. I’m so grateful for their expertise and the way they consistently show up for the team.

This morning Captain IT assisted in reconnecting to the VPN for Miller Architectural Corporation due to Firewall updates. The setup guidance was easy and Lucas guided me through the process. I requested through Lucas if we are allowed to have two VPN accounts / logins since i travel for the company and like to use the small laptop when travel by air. Josh immediately contacted Admin for approval. The attention given by Lucas was above expected. Thank you Captain IT for the continual great service.

Captain IT is a great partner! They consistently work with us in a way that matches our unique business processes and technology. Lucas and Kevin are superstars! I appreciate the direct access to knowledgeable staff who can quickly work collaboratively to fix issues rather than having to work my way up a hierarchy of support. Issues are resolved quickly and without the headaches we have had with previous vendors.

Our organization has partnered with Captain IT for several years, and their service has been consistently exceptional. Their team demonstrates a high level of technical expertise, professionalism, and reliability. Issues are addressed promptly, solutions are implemented efficiently, and their proactive approach has played a significant role in keeping our business secure and protected from technology-related risks. Captain IT’s commitment to client success is evident in every interaction. In particular, Lucas and Kevin have continually provided outstanding support. Their depth of knowledge, responsiveness, and dedication to resolving complex challenges have made them invaluable to our operations. We highly recommend Captain IT to any business seeking a dependable, knowledgeable, and security‑focused IT partner.

Our company has been working with with Captain IT for a couple of years now. Lucas is great with solving any issues I have had with my computer by remote viewing. When Lucas says he needs to return my call, he doesn’t forget! Captain IT has great customer service.

Lucas was amazing, fixed my issue with speed and courtesy, very professional, just very easy to work with. Made sure the issue was fixed before signing off. Greatly appreciate his help.
