Tony Tejada of AT TECH SYSTEMS did the entire low voltage wiring, computer system and phone system for my office. Tony is very reliable, fast and trust worthy. He went the extra mile for me. He never hesitated to do a task even if it was not a part of his contract. I recommended Tony to my brother and some other colleagues of mine. I do recommend him to anyone who needs low voltage, audio + video.
I have been working with Tony of AT TECH SYSTEMS for last 12months and have found his services to be excellent. Very knowledgeable and dependable, always available to help out in timely manner. I would recommend him for your business IT needs.

Tony installed my phone and sound system. What I like about him is the extra service he did for me. I experienced some problems with the sound system and he did what he needed to do at a very reasonable time. My phone system control broke for some reason and he was there the very next day to fix it. I've worked with other IT and computer guys who are often times hard to reach after the work is done. Tony has always been helpful when I have any questions. I've already recommended a friend to him.

I was in the process on upgrading the computer systems for my Cosmetic Dental practice in Orange, California and was referred to Tony of AT TECH SYSTEMS by OC-1 Dental. It was the smartest decision I ever made! Tony met with me right away and gave a cost estimate far below industry standard and scheduled installation two weeks after to allow for the hardware to arrive. On the installation day, they arrived on time, worked efficiently, finished on time and did a fantastic job. All systems are working as promised and whenever you have a question for Tony, he answers his phone. You just don’t find this type of customer service in the business world today, but you will with AT TECH SYSTEMS. They are always available when you need them, do quality work and have unbeatable pricing. I couldn’t have made a better choice for my business IT needs.

After some research , I decided to hire Tony to install my computers and data for my new Dental Office. From the start, he impressed me with his efficient, professional manner which not only inspired confidence but generated the results I was looking for. I am a detail oriented person but the details of the job could be overwhelming and intimidating. Tony was not only patient but took the time and explained everything in ways I could understand and process. He is very knowledgeable and helpful. So much so that I also hired him to install my telephone, security camera and audio service. I appreciate his responsiveness, prioritizing issues that arise and dealing with them quickly and efficiently, as well as his follow-up and preventative maintenance. He has a real commitment to providing excellent technical services and incredibly great customer service.

I am delighted to provide the highest testimonial for the work of AT TECH SYSTEMS in my dental office. Tony has the best customer service of any professional I have worked with. The work is of the highest caliber, and he went above and beyond the call of duty with his service and troubleshooting. He did absolutely everything in order to get our computerized digital x-ray system running perfectly. Also, the multi-media applications are great for the patients. With Tony's experience and expertise, I would recommend AT TECH SYSTEMS very highly.
Tony is a knowledgeable and competent individual. He has been an IT for a long time. He is professional and polite. I would recommend him to anyone who is looking for a reliable service. I have been very happy with his networking service at my office.
